Stormy seas ahead: Why confidence in the cruise industry has plummeted

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/jennifer-holland-969445">Jennifer Holland</a>, <a href="https://theconversation.com/institutions/university-of-suffolk-3830">University of Suffolk</a></em></p> <p>The cruise industry has weathered many storms, including fairly regular brushes with disease. Outbreaks of <a href="https://www.cdc.gov/nceh/vsp/pub/norovirus/norovirus.htm">norovirus</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3294517/">H1N1</a> and <a href="https://www.nytimes.com/2019/05/02/world/americas/measles-scientology-cruise-ship.html">measles</a> have all happened in the not too distant past. Despite this, a cruise has traditionally been regarded as a safe holiday – the kind where you don’t have to worry about a thing.</p> <p>COVID-19 has changed this. Cruise ships were a hotbed of transmission during the early stages of the pandemic, particularly the Diamond Princess, which was quarantined for six weeks in Japan in spring 2020. It had over <a href="https://www.bmj.com/content/369/bmj.m1632">700 confirmed cases</a>, and for a period was the world’s <a href="https://www.theguardian.com/world/live/2020/feb/20/coronavirus-live-updates-diamond-princess-cruise-ship-japan-deaths-latest-news-china-infections?page=with:block-5e4ea39f8f0811db2fafb3ec#block-5e4ea39f8f0811db2fafb3ec">leading COVID-19 hotspot</a> after China. Coverage of this and other ships’ outbreaks has taken its toll.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S259019822100035X">Research</a> that I conducted with colleagues in Australia shows that the pandemic has changed how people think of cruise holidays. We surveyed over 600 people in the UK and Australia, both cruisers and non-cruisers, to ask them about their willingness to cruise and future travel intentions, to explore how COVID-19 has affected perceptions of travel and cruise risks.</p> <p>Nearly 45% of interviewees had less belief than before the pandemic that cruise lines are transparent and honest about safety or health issues. Respondents were also fearful of going on a cruise, with 47% saying they don’t trust cruise lines to look after them if something goes wrong. This is staggering for an industry that depends on repeat customers.</p> <p>We further found that 67% of people are less willing to cruise as a result of the pandemic, while 69% said they feel less positive about cruising now. What’s most surprising is that even repeat cruisers said they feel nervous about cruising as a result of the pandemic, with this emotion coming up repeatedly in the survey’s open-ended questions. This is a gamechanger. Until now, loyal cruisers have always come back, with previous disease outbreaks having <a href="https://www.sciencedirect.com/science/article/abs/pii/S0261517716300309">little</a> <a href="http://ijbssnet.com/journals/Vol_4_No_7_July_2013/2.pdf">impact</a>.</p> <h2>What went wrong?</h2> <p>When the pandemic began, cruise ships immediately suffered high infection rates among passengers and crew. During the first wave, thousands were <a href="https://www.theguardian.com/world/2020/mar/27/stranded-at-sea-cruise-ships-around-the-world-are-adrift-as-ports-turn-them-away">stranded onboard</a> ships as they were held in quarantine or <a href="https://www.sciencedirect.com/science/article/abs/pii/S0160738320302103?via%3Dihub">refused entry to ports</a> as borders closed. By the end of April 2020, <a href="https://www.miamiherald.com/news/business/tourism-cruises/article241640166.html">over 50 cruise ships</a> had confirmed cases of COVID-19 and at least 65 deaths had occurred among passengers and crew.</p> <p>The story of one ship – the Ruby Princess – gained particular attention. Its passengers were allowed to disembark in Sydney in mid-March, with a number carrying the virus. The ship would go on to be linked to more than <a href="https://www.bbc.co.uk/news/world-australia-53802816">900 COVID-19 cases and 28 deaths</a>. The state of New South Wales later launched a <a href="https://www.dpc.nsw.gov.au/assets/dpc-nsw-gov-au/publications/The-Special-Commission-of-Inquiry-into-the-Ruby-Princess-Listing-1628/Report-of-the-Special-Commission-of-Inquiry-into-the-Ruby-Princess.pdf">public inquiry</a> into the ship’s outbreak and found that the state’s ministry of health made a number of serious errors in allowing passengers to get off.</p> <p>It didn’t take long for cruises to be depicted as <a href="https://www.bloomberg.com/news/articles/2020-03-24/virus-explosion-in-australia-exposes-cruise-ships-hidden-menace">places of danger and infection</a>, particularly in Australia. Lots of information about COVID-19 on cruise ships was published, especially about the <a href="https://cruiseradio.net/the-cruise-ship-story-mainstream-media-got-wrong/">Ruby Princess</a>, grabbing the <a href="https://trends.google.com/trends/explore?date=today%205-y&amp;q=Ruby%20Princess">public’s attention</a>. Undoubtedly, this amplified people’s perceptions of risk around cruise holidays. Our study found that the many stories on COVID-19 also reminded the public of previous illnesses and outbreaks onboard cruise ships.</p> <p>Given the high intensity of media interest in Australia, we weren’t surprised to find that perceived risks were higher there compared with the UK, with willingness to cruise lower. This suggests that there could be regional differences in how difficult it is for the industry to recover after the pandemic.</p> <h2>What happens next?</h2> <p>Most respondents in the study said they would wait until it was safe to cruise again – and there’s probably a long way to go on changing the current perception of cruise ships as giant incubators of disease. It’s doubtful pent-up demand from loyal cruisers will be enough to fill cruise ships to capacity – which is critical for <a href="https://link.springer.com/article/10.1057%2Fs41278-020-00158-3">long-term economic viability</a> – and so <a href="https://theconversation.com/can-the-cruise-industry-really-recover-from-coronavirus-144704">financial uncertainty</a> grows.</p> <p>The pandemic has been <a href="https://cruising.org/-/media/Facts-and-Resources/Cruise-Industry-COVID-19-FAQs_August-13-2020">catastrophic</a> for the industry so far, with financial losses of US$50 billion (£36 billion), 1.17 million job losses, 18 cruise ships sold or scrapped and at least <a href="https://www.maritime-executive.com/article/cmv-becomes-the-third-cruise-line-to-go-out-of-business-in-a-month">three cruise lines stopping trading</a>. Before the pandemic, a new cruise ship was built <a href="https://www.seatrade-cruise.com/news-headlines/golden-age-med-ports-need-prepare-new-generation-large-ships">every 47 days</a>, and off the back of the industry’s robust growth over the past two decades another <a href="https://cruising.org/en-gb/news-and-research/research/2020/december/state-of-the-cruise-industry-outlook-2021">19 ships</a> are due to enter operation in 2021, despite demand very likely to have fallen.</p> <p>To recover, the industry will need to address people’s perceptions of risk, which our research shows have heightened. Risk perception has a <a href="https://journals.sagepub.com/doi/10.1177/004728759803700209">significant influence</a> on holiday decision-making, and it will be even more critical post-COVID.</p> <p>In the wake of the pandemic, would-be cruisers will need to think about health protocols, outbreak prevention plans, onboard sanitation procedures, social distancing measures and health screenings. Also, they’ll need to consider the implications of potential outbreaks during the cruise. These could result in being quarantined in their cabin, needing to access healthcare, or even the cruise being terminated.</p> <p>All of this creates uncertainty, which adds to perceptions of risk. The industry will need to provide reassuring answers on all of these points to entice holidaymakers back onboard. Cruise companies will also need to convince customers that they are trustworthy and accountable, given the concerns about honesty and transparency raised by our research.</p> <p>Overall, the sector has been devastated by the pandemic. Possibly no other area of tourism has been as widely affected. A return to the robust growth enjoyed previously is unlikely for many years, if ever. But for there to be any chance of this happening, the industry must understand how the pandemic has affected people’s perceptions of cruises and address their concerns.<!-- Below is The Conversation's page counter tag.

These range from persistent respiratory symptoms, such as shortness of breath, to debilitating fatigue or brain fog that limits people’s ability to work, and conditions such as heart failure and diabetes, which are known to last a lifetime.</p> <p>I am a physician scientist, and I have been deeply immersed in studying long COVID since the early days of the pandemic. I have testified before the U.S. Senate as an <a href="https://www.help.senate.gov/imo/media/doc/baf4e4e7-b423-6bef-7cb4-1b272df66eb8/Al-Aly%20Testimony.pdf">expert witness on long COVID</a>, have <a href="https://scholar.google.com/citations?hl=en&amp;user=DtuRVcUAAAAJ">published extensively on it</a> and was named as one of <a href="https://time.com/6966812/ziyad-al-aly/">Time’s 100 most influential people in health in 2024</a> for my research in this area.</p> <p>Over the first half of 2024, a <a href="https://www.nationalacademies.org/our-work/long-term-health-effects-stemming-from-covid-19-and-implications-for-the-social-security-administration#sl-three-columns-afa91458-20e0-42ab-9bd6-55e3c8262ecc">flurry of reports</a> and <a href="https://doi.org/10.1056/NEJMoa2403211">scientific papers</a> on long COVID added clarity to this complex condition. These include, in particular, insights into how COVID-19 can still wreak havoc in many organs years after the initial viral infection, as well as emerging evidence on viral persistence and immune dysfunction that last for months or years after initial infection.</p> <h2>How long COVID affects the body</h2> <p>A new study that my colleagues and I published in the New England Journal of Medicine on July 17, 2024, shows that the <a href="https://doi.org/10.1056/NEJMoa2403211">risk of long COVID declined</a> over the course of the pandemic. In 2020, when the ancestral strain of SARS-CoV-2 was dominant and vaccines were not available, about 10.4% of adults who got COVID-19 developed long COVID. By early 2022, when the omicron family of variants predominated, that rate declined to 7.7% among unvaccinated adults and 3.5% of vaccinated adults. In other words, unvaccinated people were more than twice as likely to develop long COVID.</p> <p>While researchers like me do not yet have concrete numbers for the current rate in mid-2024 due to the time it takes for long COVID cases to be reflected in the data, the flow of new patients into long COVID clinics has been on par with 2022.</p> <p>We found that the decline was the result of two key drivers: availability of vaccines and changes in the characteristics of the virus – which made the virus less prone to cause severe acute infections and may have reduced its ability to persist in the human body long enough to cause chronic disease.</p> <p>Despite the decline in risk of developing long COVID, even a 3.5% risk is substantial. New and repeat COVID-19 infections translate into millions of new long COVID cases that add to an already staggering number of people suffering from this condition.</p> <p>Estimates for the first year of the pandemic suggests that at <a href="https://doi.org/10.1038/s41579-023-00896-0">least 65 million people</a> globally have had long COVID. Along with a group of other leading scientists, my team will soon publish updated estimates of the global burden of long COVID and its impact on the global economy through 2023.</p> <p>In addition, a major new report by the National Academies of Sciences Engineering and Medicine details all the <a href="https://nap.nationalacademies.org/catalog/27756/long-term-health-effects-of-covid-19-disability-and-function">health effects that constitute long COVID</a>. The report was commissioned by the Social Security Administration to understand the implications of long COVID on its disability benefits.</p> <p>It concludes that long COVID is a complex chronic condition that can result in more than 200 health effects across multiple body systems.

Importantly, <a href="https://doi.org/10.1126/science.adl0867">more than 90% of people with long COVID</a> had mild COVID-19 infections.</p> <p>The National Academies report also concluded that long COVID can result in the inability to return to work or school; poor quality of life; diminished ability to perform activities of daily living; and decreased physical and cognitive function for months or years after the initial infection.</p> <p>The report points out that many health effects of long COVID, such as post-exertional malaise and chronic fatigue, cognitive impairment and autonomic dysfunction, are not currently captured in the <a href="https://www.ssa.gov/disability/professionals/bluebook/AdultListings.htm">Social Security Administration’s Listing of Impairments</a>, yet may significantly affect an individual’s ability to participate in work or school.</p> <figure><iframe src="https://www.youtube.com/embed/9kJ5GWb2wzw?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Many people experience long COVID symptoms for years following initial infection.</span></figcaption></figure> <h2>A long road ahead</h2> <p>What’s more, health problems resulting from COVID-19 can last years after the initial infection.</p> <p>A large study published in early 2024 showed that even people who had a <a href="https://doi.org/10.1038/s41591-024-02987-8">mild SARS-CoV-2 infection still experienced new health problems</a> related to COVID-19 in the third year after the initial infection.</p> <p>Such findings parallel other research showing that the <a href="https://doi.org/10.1016/S1473-3099(24)00171-3">virus persists</a> in various organ systems for months or years after COVID-19 infection. And research is showing that immune responses to the infection are <a href="https://doi.org/10.1126/scitranslmed.adk3295">still evident two to three years</a> after a mild infection. Together, these studies may explain why a SARS-CoV-2 infection years ago could still cause new health problems long after the initial infection.</p> <p>Important progress is also being made in understanding the pathways by which long COVID wreaks havoc on the body. Two preliminary studies <a href="https://doi.org/10.1101/2024.06.18.24309100">from the U.S.</a> and <a href="https://doi.org/10.1101/2024.05.30.596590">the Netherlands</a> show that when researchers transfer auto-antibodies – antibodies generated by a person’s immune system that are directed at their own tissues and organs – from people with long COVID into healthy mice, the animals start to experience long COVID-like symptoms such as muscle weakness and poor balance.</p> <p>These studies suggest that an abnormal immune response thought to be responsible for the generation of these auto-antibodies may underlie long COVID and that <a href="https://doi.org/10.1126/science.zbzipqn">removing these auto-antibodies</a> may hold promise as potential treatments.</p> <h2>An ongoing threat</h2> <p>Despite overwhelming evidence of the wide-ranging risks of COVID-19, a great deal of messaging suggests that it is no longer a threat to the public. Although there is no empirical evidence to back this up, this misinformation has permeated the public narrative.</p> <p>The data, however, tells a different story.</p> <p><a href="https://covid.cdc.gov/covid-data-tracker/#datatracker-home">COVID-19 infections</a> continue to <a href="https://www.cdc.gov/flu/weekly/index.htm">outnumber flu cases</a> and lead to <a href="https://www.cdc.gov/resp-net/dashboard/index.html">more hospitalization</a> and <a href="https://doi.org/10.1001/jama.2024.7395">death</a> than the flu.

Joe Biden has COVID. Here’s what someone over 80 can expect

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>If US politics leading up to the 2024 presidential election was a Hollywood thriller, it would be a movie full of plot twists and surprises. The latest twist is President Joe Biden has <a href="https://edition.cnn.com/2024/07/17/politics/joe-biden-tests-positive-covid-19/index.html">COVID</a> and is isolating at home.</p> <p><a href="https://www.whitehouse.gov/briefing-room/statements-releases/2024/07/17/statement-from-press-secretary-karine-jean-pierre-3/">Biden’s doctor says</a> his symptoms are mild and include a runny nose, cough and generally feeling unwell. His temperature, oxygen levels and respiratory rate are said to be normal.</p> <p>Biden, who has <a href="https://www.bbc.com/news/articles/cv2gj8314nqo">been diagnosed</a> with COVID twice before, <a href="https://www.whitehouse.gov/briefing-room/statements-releases/2024/07/17/statement-from-press-secretary-karine-jean-pierre-3/">has received</a> his COVID vaccine and booster shots, and has taken the first dose of the antiviral drug Paxlovid.</p> <p>No doubt, Biden will be receiving the best of medical care. Yet, as much <a href="https://theconversation.com/is-joe-biden-experiencing-cognitive-decline-heres-why-we-shouldnt-speculate-234487">recent media coverage</a> reminds us, he is 81 years old.</p> <p>So let’s look at what it means for an 81-year-old man to have COVID in 2024. Of course, Biden is not just any man, but we’ll come to that later.</p> <h2>Luckily, it’s not 2020</h2> <p>If we were back in 2020, a COVID diagnosis at this age would have been a big deal.</p> <p>This was a time before COVID vaccines, before specific COVID treatments and before we knew as much about COVID as we do today. Back then, being over 80 and being infected with the SARS-CoV-2 virus (the virus that causes COVID) represented a significant threat to your health.</p> <p>It was very clear early in the pandemic that your chances of getting severe disease and dying <a href="https://theconversation.com/why-are-older-people-more-at-risk-of-coronavirus-133770">increased with age</a>. The early data suggested that if you were over 80 and infected, you had about a 15% likelihood of dying from the illness.</p> <p>Also, if you did develop severe disease, we didn’t have a lot in the toolkit to deal with your infection.</p> <p>Remember, former UK Prime Minister Boris Johnson <a href="https://theconversation.com/scott-morrison-has-covid-its-a-big-deal-but-not-how-you-think-178298">ended up in the ICU</a> with his COVID infection in <a href="https://www.theguardian.com/world/2020/apr/17/boris-johnson-and-coronavirus-inside-story-illness">April 2020</a>, despite being 55 at the time. That’s a much younger age than Biden is now.</p> <p>Former US President Donald Trump also had what was understood to be a <a href="https://www.theguardian.com/us-news/2021/feb/11/trump-coronavirus-ventilator-covid-illness">very severe case</a> of COVID in October 2020. He was 74 at the time.</p> <h2>How things have changed</h2> <p>So let’s wind the clock forward to 2024. A lot has happened in four years.</p> <p>COVID is still a disease that needs to be <a href="https://www.cdc.gov/ncird/whats-new/changing-threat-covid-19.html">taken seriously</a>. And for some people with other health conditions (for instance, people with heart disease or diabetes) it poses more of a threat. And of course we know more about the well-publicised <a href="https://theconversation.com/i-have-covid-how-likely-am-i-to-get-long-covid-218808">longer term effects</a> of COVID.</p> <p>But the threat COVID poses to an individual is far less now than it has ever been.</p> <h2>More of us have some immunity</h2> <p>First, <a href="https://www.theguardian.com/world/2022/dec/03/who-estimates-90-of-world-have-some-resistance-to-covid">most people</a> have some immunity to COVID now, whether this has come from vaccination or prior infection, and for many both.</p> <p>The fact that your immune system has had some exposure to the virus is transformative in how you respond to infection. Yes, there’s the ongoing problem of waning immunity over time and the virus mutating meaning you need to have regular booster vaccines. But as your immune system has “seen” the virus before it allows it to respond more effectively. This means the threat posed by infection has fallen drastically.</p> <p>We know Biden has received his booster shots. Boosters have been shown to offer <a href="https://theconversation.com/what-are-the-new-covid-booster-vaccines-can-i-get-one-do-they-work-are-they-safe-217804">substantial protection</a> against severe illness and death and are particularly important for older age groups.</p> <h2>Now we have antivirals</h2> <p>Second, we also have antiviral medicines, such as Paxlovid, which is effective in reducing the likelihood of severe illness from COVID if taken soon after developing symptoms.</p> <p>In <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2118542">one study</a>, if taken soon after infection, Paxlovid reduced the likelihood of severe illness or death by 89%. So it is <a href="https://www.covid19treatmentguidelines.nih.gov/therapies/antivirals-including-antibody-products/ritonavir-boosted-nirmatrelvir--paxlovid-/">highly recommended</a> for those at higher risk of severe illness. As we know, Biden is taking Paxlovid.</p> <p>Paxlovid has also been associated with rebound symptoms. This is when a person looks to have recovered from infection only to have symptoms reappear. Biden experienced this <a href="https://theconversation.com/why-do-some-people-who-take-paxlovid-for-covid-get-rebound-symptoms-or-test-positive-again-like-president-biden-188002">in 2022</a>.</p> <p>The good news is that even if this occurs in most instances the symptoms associated with the recurrence tend to be mild.</p> <h2>Biden would have the best care</h2> <p>The other factor of course is that Biden would have access to some of the world’s best medical care.</p> <p>If his symptoms were to become more severe or any complications were to develop, you can be assured he would get the best treatment.</p> <p>So is Biden’s diagnosis news? Well of course, given all the speculation about his health. But in terms of COVID being a major threat to Biden’s health, there are no indications it should be.<!-- Below is The Conversation's page counter tag.

Are you up to date with your COVID, flu and other shots? It might depend on who your GP is

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/peter-breadon-1348098">Peter Breadon</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> and <a href="https://theconversation.com/profiles/anika-stobart-1014358">Anika Stobart</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a></em></p> <p>Too many older Australians are <a href="https://grattan.edu.au/wp-content/uploads/2023/11/A-fair-shot-How-to-close-the-vaccination-gap-Grattan-Institute-Report.pdf">missing out</a> on recommended vaccinations for COVID, flu, shingles and pneumococcal that can protect them from serious illness, hospitalisation and even death.</p> <p>A new <a href="https://grattan.edu.au/">Grattan Institute report</a> shows vaccination rates vary widely from GP to GP, highlighting an important place to look for opportunities to boost vaccination.</p> <p>Many people get vaccinated at pharmacies, and those vaccinations are counted in our analysis. But we looked at GPs because they have a unique role overseeing someone’s health care, and an important role promoting vaccination.</p> <p>We found that for some GPs, nine in ten of their older patients were vaccinated for flu. For others, the rate was only four in ten. The differences for shingles and COVID were even bigger. For pneumococcal disease, there was a 13-fold difference in GPs’ patient vaccination rates.</p> <p>While some variation is inevitable, these differences are large, and they result in too many people missing out on recommended vaccines.</p> <h2>Some GPs treat more complex patients</h2> <p>A lot of these differences reflect the fact that GPs see different types of patients.</p> <p>Our research shows older people who aren’t proficient in English are up to 15% less likely to be vaccinated, even after other factors are taken into account. And the problem seems to be getting worse.</p> <p>COVID vaccination rates for people 75 years and older fell to just 36% in May 2024. But rates were even lower – a mere 11% – for people who don’t speak English proficiently, and 15% for those who speak a language other than English at home.</p> <p>Given these results, it’s no surprise that GPs with fewer patients who are vaccinated also have more patients who struggle with English. For GPs with the lowest vaccination rates, one-quarter of their patients aren’t proficient in English. For GPs with the highest vaccination rates, it is only 1%.</p> <p>GPs with fewer vaccinated patients also saw more people who live in rural areas, are poorer, didn’t go to university, and don’t have regular access to a GP, all of which reduce the likelihood of getting vaccinated.</p> <p>Many of these barriers to vaccination are difficult for GPs to overcome. They point to structural problems in our health system, and indeed our society, that go well beyond vaccination.</p> <p>But GPs are also a key part of the puzzle. A <a href="https://www.ijidonline.com/article/S1201-9712(14)01379-4/fulltext">strong</a> <a href="https://www.tandfonline.com/doi/full/10.1080/21645515.2020.1780848">recommendation</a> from a GP can make a big difference to whether a patient gets vaccinated. <a href="https://www.aihw.gov.au/reports/primary-health-care/general-practice-allied-health-primary-care">Nearly all</a> older Australians visit a GP every year. And some GPs have room for improvement.</p> <h2>But GPs seeing similar patients can have very different vaccination rates</h2> <p>We compared GPs whose patients had a similar likelihood of being vaccinated, based on a range of factors including their health, wealth and cultural background.</p> <p>Among the GPs whose patients were least likely to get a flu vaccination, some saw less than 40% of their patients vaccinated, while for others in that group, the rate was over 70%.</p> <p>Among GPs with patients who face few barriers to vaccination, the share of their patients who were vaccinated also varied widely.</p> <p>Even within neighbourhoods, GP patient vaccination rates vary a lot. For example, in Bankstown in Sydney, there was a seven-fold difference in COVID vaccination rates and an 18-fold difference for pneumococcal vaccination.</p> <p>Not everything about clinics and patients can be measured in data, and there will be good reasons for some of these differences.</p> <p>But the results do suggest that some GPs are beating the odds to overcome patient barriers to getting vaccinated, while other GPs could be doing more. That should trigger focused efforts to raise vaccination rates where they are low.</p> <h2>So what should governments do?</h2> <p>A comprehensive national reform agenda is <a href="https://grattan.edu.au/wp-content/uploads/2023/11/A-fair-shot-How-to-close-the-vaccination-gap-Grattan-Institute-Report.pdf">needed to increase adult vaccination</a>. That includes clearer guidance, national advertising campaigns, SMS reminders, and tailored local programs that reach out to communities with very low levels of vaccination.</p> <p>But based on the big differences in GPs’ patient vaccination rates, Australia also needs a three-pronged plan to help GPs lift older Australians’ vaccination rates.</p> <p>First, the way general practice is funded needs to be overhauled, providing more money for the GPs whose patients face higher barriers to vaccination. Today, clinics with patients who are poorer, sicker and who struggle with English tend to get less funding. They should get more, so they can spend more time with patients to explain and promote vaccination.</p> <p>Second, GPs need to be given data, so that they can easily see how their vaccination rates compare to GPs with similar patients.</p> <p>And third, Primary Health Networks – which are responsible for improving primary care in their area – should give clinics with low vaccination rates the help they need. That might include running vaccination sessions, sharing information about best practices that work in similar clinics with higher vaccination rates, or offering translation support.</p> <p>And because pharmacies also play an important role in promoting and providing vaccines, governments should give them data too, showing how their rates compare to other pharmacies in their area, and support to boost vaccination uptake.</p> <p>These measures would go a long way to better protect some of the most vulnerable in our society. Governments have better data than ever before on who is missing out on vaccinations – and other types of health care.</p> <p>They shouldn’t miss the opportunity to target support so that no matter where you live, what your background is, or which GP or pharmacy you go to, you will have the best chance of being protected against disease.<!-- Below is The Conversation's page counter tag.

We finally know why some people got COVID while others didn’t

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/marko-nikolic-1543289">Marko Nikolic</a>, <a href="https://theconversation.com/institutions/ucl-1885">UCL</a> and <a href="https://theconversation.com/profiles/kaylee-worlock-1543639">Kaylee Worlock</a>, <a href="https://theconversation.com/institutions/ucl-1885">UCL</a></em></p> <p>Throughout the pandemic, one of the key questions on everyone’s mind was why some people avoided getting COVID, while others caught the virus multiple times.</p> <p>Through a collaboration between University College London, the Wellcome Sanger Institute and Imperial College London in the UK, we set out to answer this question using the world’s first controlled <a href="https://www.nature.com/articles/s41591-022-01780-9">“challenge trial” for COVID</a> – where volunteers were deliberately exposed to SARS-CoV-2, the virus that causes COVID, so that it could be studied in great detail.</p> <p>Unvaccinated healthy volunteers with no prior history of COVID were exposed – via a nasal spray – to an extremely low dose of the original strain of SARS-CoV-2. The volunteers were then closely monitored in a quarantine unit, with regular tests and samples taken to study their response to the virus in a highly controlled and safe environment.</p> <p>For our <a href="https://www.nature.com/articles/s41586-024-07575-x">recent study</a>, published in Nature, we collected samples from tissue located midway between the nose and the throat as well as blood samples from 16 volunteers. These samples were taken before the participants were exposed to the virus, to give us a baseline measurement, and afterwards at regular intervals.</p> <p>The samples were then processed and analysed using single-cell sequencing technology, which allowed us to extract and sequence the genetic material of individual cells. Using this cutting-edge technology, we could track the evolution of the disease in unprecedented detail, from pre-infection to recovery.</p> <p>To our surprise, we found that, despite all the volunteers being carefully exposed to the exact same dose of the virus in the same manner, not everyone ended up testing positive for COVID.</p> <p>In fact, we were able to divide the volunteers into three distinct infection groups (see illustration). Six out of the 16 volunteers developed typical mild COVID, testing positive for several days with cold-like symptoms. We referred to this group as the “sustained infection group”.</p> <p>Out of the ten volunteers who did not develop a sustained infection, suggesting that they were able to fight off the virus early on, three went on to develop an “intermediate” infection with intermittent single positive viral tests and limited symptoms. We called them the “transient infection group”.</p> <p>The final seven volunteers remained negative on testing and did not develop any symptoms. This was the “abortive infection group”. This is the first confirmation of abortive infections, which were previously <a href="https://www.nature.com/articles/s41586-021-04186-8">unproven</a>. Despite differences in infection outcomes, participants in all groups shared some specific novel immune responses, including in those whose immune systems prevented the infection.</p> <p>When we compared the timings of the cellular response between the three infection groups, we saw distinct patterns. For example, in the transiently infected volunteers where the virus was only briefly detected, we saw a strong and immediate accumulation of immune cells in the nose one day after infection.</p> <p>This contrasted with the sustained infection group, where a more delayed response was seen, starting five days after infection and potentially enabling the virus to take hold in these volunteers.</p> <p>In these people, we were able to identify cells stimulated by a key antiviral defence response in both the nose and the blood. This response, called the “interferon” response, is one of the ways our bodies signal to our immune system to help fight off viruses and other infections. We were surprised to find that this response was detected in the blood before it was detected in the nose, suggesting that the immune response spreads from the nose very quickly.</p> <h2>Protective gene</h2> <p>Lastly, we identified a specific gene called HLA-DQA2, which was expressed (activated to produce a protein) at a much higher level in the volunteers who did not go on to develop a sustained infection and could hence be used as a marker of protection. Therefore, we might be able to use this information and identify those who are probably going to be protected from severe COVID.</p> <p>These findings help us fill in some gaps in our knowledge, painting a much more detailed picture regarding how our bodies react to a new virus, particularly in the first couple of days of an infection, which is crucial.</p> <p>We can use this information to compare our data to other data we are currently generating, specifically where we are “challenging” volunteers to other viruses and more recent strains of COVID. In contrast to our current study, these will mostly include volunteers who have been vaccinated or naturally infected – that is, people who already have immunity.</p> <p>Our study has significant implications for future treatments and vaccine development. By comparing our data to volunteers who have never been exposed to the virus with those who already have immunity, we may be able to identify new ways of inducing protection, while also helping the development of more effective vaccines for future pandemics. In essence, our research is a step towards better preparedness for the next pandemic.<!-- Below is The Conversation's page counter tag.

COVID vaccines saved millions of lives – linking them to excess deaths is a mistake

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/paul-hunter-991309">Paul Hunter</a>, <em><a href="https://theconversation.com/institutions/university-of-east-anglia-1268">University of East Anglia</a></em></p> <p>A recent <a href="https://bmjpublichealth.bmj.com/content/2/1/e000282">study</a> has sparked another <a href="https://nypost.com/2024/06/06/us-news/covid-vaccines-may-have-helped-fuel-rise-in-excess-deaths-since-pandemic-study/">round of</a> <a href="https://www.telegraph.co.uk/news/2024/06/04/covid-vaccines-may-have-helped-fuel-rise-in-excess-deaths/">headlines</a> <a href="https://www.gbnews.com/health/covid-vaccine-side-effects-deaths">claiming</a> that COVID vaccines caused excess deaths. This was accompanied by a predictable outpouring of <a href="https://x.com/DrAseemMalhotra/status/1797922073798717524">I-told-you-sos</a> on social media.</p> <p>Excess deaths are a measure of how many more deaths are being recorded in a country over what would have been expected based on historical trends. In the UK, and in many other countries, death rates have been higher during the years 2020 to 2023 than would have been expected based on historic trends from before the pandemic. But that has been known for some time. A couple of years ago I wrote an article for <a href="https://theconversation.com/summer-2022-saw-thousands-of-excess-deaths-in-england-and-wales-heres-why-that-might-be-189351">The Conversation</a> pointing this out and suggesting some reasons. But has anything changed?</p> <p>The authors of the new study, published in BMJ Public Health, used publicly available data from <a href="https://ourworldindata.org/COVID-vaccinations">Our World in Data</a> to determine which countries had “statistically significant” excess deaths – in other words, excess deaths that couldn’t be explained by mere random variation.</p> <p>They studied the years 2020 to 2022 and found that many, but not all, countries did indeed report excess deaths. The authors did not try to explain why these excess deaths occurred, but the suggestion that COVID vaccines could have played a role is clear from their text – and indeed widely interpreted as such by certain newspapers.</p> <p>There is no doubt that a few deaths were associated with <a href="https://journals.sagepub.com/doi/full/10.1177/25166026211053485">the COVID vaccines</a>, but could the vaccination programme explain the large number of excess deaths – 3 million in 47 countries – that have been reported?</p> <p>Based on <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths/articles/excessdeathsinenglandandwales/march2020todecember2021">death certificates</a>, during 2020 and 2021 there were more deaths from COVID than estimated excess deaths in the UK. So during the year 2021 when most vaccine doses were administered, there were actually fewer non-COVID deaths than would have been expected. It was only in 2022 that excess deaths <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths/articles/deathregistrationsummarystatisticsenglandandwales/2022">exceeded COVID deaths</a>.</p> <p>If the vaccination campaign was contributing to the excess deaths that we have seen in recent years, then we should expect to see more deaths in people who have been vaccinated than in those who have not. The most reliable analysis in this regard was done by the UK’s <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths/articles/excessdeathsinenglandandwales/march2020todecember2021">Office for National Statistics (ONS)</a>. In this analysis, the ONS matched death registrations with the vaccine histories of each death recorded. They then calculated “age-standardised death rates” to account for age differences between those vaccinated and those not.</p> <p>What the ONS found was that in all months from April 2021 to May 2023, the death rate <a href="https://www.ons.gov.uk/redir/eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpbmRleCI6MSwicGFnZVNpemUiOjEwLCJwYWdlIjoxLCJ1cmkiOiIvcGVvcGxlcG9wdWxhdGlvbmFuZGNvbW11bml0eS9iaXJ0aHNkZWF0aHNhbmRtYXJyaWFnZXMvZGVhdGhzL2RhdGFzZXRzL2V4Y2Vzc2RlYXRoc2luZW5nbGFuZGFuZHdhbGVzIiwibGlzdFR5cGUiOiJyZWxhdGVkZGF0YSJ9.Cot-XDe8Rr07paGllBNnVVz1nTqnXfVafn2woA3tk0c">from all causes was higher</a> in the unvaccinated than in people who had been vaccinated at least once.</p> <p>That deaths from all causes were lower in the vaccinated than the unvaccinated should come as no surprise given that COVID was a major cause of death in 2021 and 2022. And there is ample evidence of the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10492612/">protective effect of vaccines</a> against severe COVID and death. But what is even more convincing is that, even when known COVID deaths were excluded in the ONS report, the death rate in the unvaccinated was still higher, albeit not by very much in more recent months.</p> <p>Some COVID deaths would certainly not have been recognised as such. But, on the other hand, people with chronic conditions, such as diabetes, were a high priority for vaccination. And these people would have been at increased risk of death even before the pandemic.</p> <h2>Possible causes</h2> <p>If the vaccine is not the cause of the excess deaths, what was?</p> <p>The major cause of the excess deaths reported in the first two years of the BMJ Public Health study was deaths from COVID. But by 2022, excess deaths exceeded COVID deaths in many countries.</p> <p>Possible <a href="https://theconversation.com/summer-2022-saw-thousands-of-excess-deaths-in-england-and-wales-heres-why-that-might-be-189351">explanations</a> for these excess deaths include longer-term effects of earlier COVID infections, the return of infections such as influenza that had been suppressed during the COVID control measures, adverse effects of lockdowns on physical and mental health, and delays in the diagnosis of life-threatening infections as health services struggled to cope with the pandemic and its aftermath.</p> <p>We do need to look very carefully at how the pandemic was managed. There is still considerable debate about the effectiveness of different behavioural control measures, such as self-isolation and lockdowns. Even when such interventions were effective at reducing transmission of COVID, what were the harms and were the gains worth the harms? Nevertheless, we can be confident that the excess deaths seen in recent years were not a consequence of the vaccination campaign.<!-- Below is The Conversation's page counter tag.

AstraZeneca admits to Covid vaccine's deadly side effect

<p>AstraZeneca has admitted that their Covid vaccine carries a very rare but deadly side effect, as "dozens" of class-action lawsuits pile up. </p> <p>The UK pharmaceutical giant could be facing damages of up to $38 million, as lawyers representing complainants whose loved ones who were injured or killed from the jab called the vaccine "defective". </p> <p>Those who received the AstraZeneca Covid-19 vaccine could be susceptible to a rare and potentially blood clotting disorder called thrombosis with thrombocytopenia syndrome, or TTS, in which patients suffer from blood clots as well as a low blood platelet count. </p> <p>While the side effect is rare, recent research from RMIT University and Monash University found Australia’s Covid-19 vaccination rollout likely prevented the death of 17,760 people aged over 50 in New South Wales between August 2021 and July 2022, with some researchers suggesting that AstraZeneca alone helped saved as many as six million lives worldwide, according to the <a title="nypost.com" href="https://nypost.com/2024/04/29/world-news/astrazeneca-cops-to-rare-deadly-side-effect-of-covid-jab-as-lawsuits-mount/"><em>New York Post</em>.</a></p> <p>AstraZeneca, which is contesting the claims, acknowledged in a February legal document that its vaccine can “in very rare cases,” cause the clotting condition, while also acknowledging that the potential complication was listed as a side effect of the vaccine since its release.</p> <p>So far, 51 cases have been filed in London’s High Court, estimated to be worth around $190 million (GBP100 million) total, according to the UK newspaper<a title="www.telegraph.co.uk" href="https://www.telegraph.co.uk/news/2024/04/28/astrazeneca-admits-covid-vaccine-causes-rare-side-effect/"> <em>The Telegraph</em></a>.</p> <p>However, thanks to a deal struck between AstraZeneca and the UK government during the worst of the pandemic, the drugmaker has been pre-emptively indemnified against future lawsuits – which means any successful claims for payouts will be born by taxpayers.</p> <p>One of the claimants is father-of-two Jamie Scott, who was left with a permanent brain injury after suffering a clot following receiving the vaccine in April 2021. </p> <p>His wife, Kate, told <a title="www.telegraph.co.uk" href="https://www.telegraph.co.uk/news/2024/04/28/astrazeneca-admits-covid-vaccine-causes-rare-side-effect/"><em>The Telegraph</em> </a>she’s hopeful the company’s admission will accelerate the outcome of their case.</p> <p>“We need an apology, fair compensation for our family and other families who have been affected. We have the truth on our side, and we are not going to give up.”</p> <p><em>Image credits: Getty Images </em></p>

Christina Applegate details bout of Covid and Sapovirus amid MS battle

<p>Christina Applegate has detailed her latest health battle amid her multiple sclerosis (MS).</p> <p>Speaking on her <em>MesSy</em> podcast with co-host Jamie-Lynn Sigler, the actress revealed her rough experience after contracting Covid for the first time, which then turned into long Covid, and to make matters worse, she then contracted Sapovirus from contaminated food. </p> <p>Sapoviruses can cause acute gastroenteritis, and the actress candidly shared that she had been wearing diapers in recent weeks because of how often she has had to go to the bathroom. </p> <p>"I finally got the Covies.. someone real close to me dropped the ball and came home with the stuff and it spread all over the house," she began.</p> <p>"I had one day when I had a headache and chills and I thought I was making it through this."</p> <p>"It turned into long covid and it turned into a chest infection and then my heart was doing weird stuff, where it just speeds up... so I was like mother f--ker!"</p> <p>She then continued, saying that after contracting the virus she was "p---ing out of her a** for a few days".</p> <p>"I was so dizzy. I was so sick. I couldn't eat... Someone else's poop went into my mouth and I ate it."</p> <p>The actress recently revealed that she has 30 lesions on her brain from her MS,  a condition where the body's own immune system mistakenly attacks and damages the fatty material around the nerves, which can cause a range of symptoms. </p> <p>It is the most common acquired chronic neurological disease affecting young adults, according to MS Australia. </p> <p><em>Image: Getty</em></p>

Dad awarded compensation after developing heart issue from mandatory vaccine

<p>An Adelaide father is set to receive hefty compensation after a mandatory Covid jab left him with a debilitating health condition. </p> <p>In 2021 at the height of the Covid pandemic in Australia, 44-year-old Daniel Shepherd was required to receive tow Covid vaccinations, due to his hands on role at an aged care facility. </p> <p>After having two Pfizer vaccines, he suffered some adverse effects, but dismissed his symptoms as nothing serious. </p> <p>In the months after, Shepherd was required to have a booster shot when he began a new job with the Department of Child Protection in October of the same year. </p> <p>In January 2022, the father was told if we wanted to keep his job as a health and childcare worker, he needed to have the jab. </p> <p>After eventually agreeing to the booster, Shepherd has his third dose of Pfizer in late February 2022, but began suffering from chest pains just hours later. </p> <p>"It felt like someone had their knee right on my chest," he told <a href="https://www.9news.com.au/national/adelaide-news-covid-vaccine-man-to-get-government-compensation-after-developing-heart-condition/55cc0fbf-4631-4cf0-b395-8c8b6c71a43f" target="_blank" rel="noreferrer noopener"><em>9News</em>.</a></p> <p>The pain kept getting worse until he was rushed to hospital a few weeks later when he thought he was having a heart attack.</p> <p>There he was diagnosed with post-vaccine pericarditis: an inflammation of the membrane around the heart.</p> <p>His illness meant he was unable to work full time, and also meant he was unable to keep up with his young son.</p> <p>"Even today with just mild exertion [I get] chest pains and then it's followed by fatigue, like severe fatigue," Shepard said.</p> <p>"It's heartbreaking to have to say 'sorry buddy, daddy's tired'." </p> <p>Mr Shepherd decided to take legal action after he was unable to work, launching a workers compensation claim against the government.</p> <p>In a landmark ruling in mid-January, the South Australian Employment Tribunal agreed to pay weekly compensation and medical bills to Shepherd.</p> <p>Doctors were unanimous in his case that the vaccine was the cause of his inability to work, but the government argued emergency directions that were in place at the time trumped the laws around workplace injury.</p> <p>Pericarditis is meant to clear within a few months, but Shepherd's symptoms have plagued him for almost two years.</p> <p><em>Image credits: 9News</em></p>

How long does immunity last after a COVID infection?

<p><em><a href="https://theconversation.com/profiles/lara-herrero-1166059">Lara Herrero</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> and <a href="https://theconversation.com/profiles/dr-wesley-freppel-1408971">Dr Wesley Freppel</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p>Nearly four years into the pandemic, Australia, like many other countries, is still seeing large numbers of <a href="https://nindss.health.gov.au/pbi-dashboard/">COVID cases</a>. Some 860,221 infections were recorded around the country in 2023, while 30,283 cases have already been reported in 2024.</p> <p>This is likely to be a significant underestimate, with fewer people testing and reporting than earlier in the pandemic. But the signs suggest parts of Australia are experiencing yet <a href="https://www.abc.net.au/news/2024-01-23/covid-19-case-numbers-from-australia-states-and-territories/103374656">another COVID surge</a>.</p> <p>While some lucky people claim to have never had COVID, many are facing our second, third or even fourth infection, often despite having been vaccinated. You might be wondering, how long does immunity last after a previous infection or vaccination?</p> <p>Let’s take a look at what the evidence shows.</p> <h2>B cells and T cells</h2> <p>To answer this question, we need to understand a bit about how <a href="https://theconversation.com/what-happens-in-our-body-when-we-encounter-and-fight-off-a-virus-like-the-flu-sars-cov-2-or-rsv-207023">immunity</a> to SARS-CoV-2 (the virus that causes COVID) works.</p> <p>After being infected or vaccinated, the immune system develops specific antibodies that can neutralise SARS-CoV-2. B cells remember the virus for a period of time. In addition, the immune system produces memory T cells that can kill the virus, and remain in the blood for some months after the clearance of the infection or a vaccination.</p> <p>A <a href="https://www.science.org/doi/full/10.1126/science.abf4063?rfr_dat=cr_pub++0pubmed&amp;url_ver=Z39.88-2003&amp;rfr_id=ori%3Arid%3Acrossref.org">2021 study</a> found 98% of people had antibodies against SARS-CoV-2’s spike protein (a protein on the surface of the virus that allows it to attach to our cells) one month after symptom onset. Six to eight months afterwards, 90% of participants still had these neutralising antibodies in their blood.</p> <p>This means the immune system should have recognised and neutralised the same SARS-CoV-2 variant if challenged within six to eight months (if an infection occurred, it should have resulted in mild to no symptoms).</p> <h2>But what about when the virus mutates?</h2> <p>As we know, SARS-CoV-2 has mutated over time, leading to the emergence of new variants such as alpha, beta, delta and omicron. Each of these variants carries mutations that are new to the immune system, even if the person has been previously infected with an earlier variant.</p> <p>A new variant likely won’t be <a href="https://www.science.org/doi/10.1126/science.adj0070">perfectly recognised</a> – or even <a href="https://www.cell.com/cell/pdf/S0092-8674(21)01578-6.pdf">recognised at all</a> – by the already activated memory T or B cells from a previous SARS-CoV-2 infection. This could explain why people can be so readily reinfected with COVID.</p> <p>A recent <a href="https://www.thelancet.com/article/S0140-6736(22)02465-5/fulltext#seccestitle10">review of studies</a> published up to the end of September 2022 looked at the protection conferred by previous SARS-CoV-2 infections.</p> <p>The authors found a previous infection provided protective immunity against reinfection with the ancestral, alpha, beta and delta variants of 85.2% at four weeks. Protection against reinfection with these variants remained high (78.6%) at 40 weeks, or just over nine months, after the previous infection. This protection decreased to 55.5% at 80 weeks (18 months), but the authors noted there was a lack of data at this time point.</p> <p>Notably, an earlier infection provided only 36.1% protection against a reinfection with omicron BA.1 at 40 weeks. Omicron has been described as an <a href="https://www.nature.com/articles/s41564-022-01143-7">immune escape variant</a>.</p> <p>A prior infection showed a high level of protection against severe disease (above 88%) up to 40 weeks regardless of the variant a person was reinfected with.</p> <h2>What about immunity after vaccination?</h2> <p>So far almost 70 million COVID vaccines <a href="https://www.health.gov.au/topics/covid-19/reporting">have been administered</a> to more than <a href="https://www.health.gov.au/resources/publications/covid-19-vaccine-rollout-update-12-january-2023?language=en">22 million people</a> in Australia. Scientists estimated COVID vaccines prevented around <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(22)00320-6/fulltext">14.4 million deaths</a> in 185 countries in the first year after they became available.</p> <p>But we know COVID vaccine effectiveness wanes over time. A <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2804451?utm_source=For_The_Media&amp;utm_medium=referral&amp;utm_campaign=ftm_links&amp;utm_term=050323">2023 review</a> found the original vaccines were 79.6% and 49.7% effective at protecting against symptomatic delta infection at one and nine months after vaccination respectively. They were 60.4% and 13.3% effective against symptomatic omicron at the same time points.</p> <p>This is where booster doses come into the picture. They’re important to keep the immune system ready to fight off the virus, particularly for those who are more vulnerable to the effects of a COVID infection.</p> <p>Plus, regular booster doses can provide immunity against different variants. COVID vaccines are constantly being <a href="https://mvec.mcri.edu.au/references/covid-19/">reviewed and updated</a> to ensure optimal protection against <a href="https://www.who.int/activities/tracking-SARS-CoV-2-variants">current circulating strains</a>, with the latest shot available designed to target <a href="https://www.health.gov.au/ministers/the-hon-mark-butler-mp/media/new-covid-19-vaccines-available-to-target-current-variants">the omicron variant XBB 1.5</a>. This is similar to how we approach seasonal flu vaccines.</p> <p>A <a href="https://www.nature.com/articles/s41598-023-50335-6">recent study</a> showed a COVID vaccination provides longer protection against reinfection than natural protection alone. The median time from infection to reinfection in non-vaccinated people was only six months, compared with 14 months in people who had received one, two or three doses of vaccine after their first infection. This is called <a href="https://www.science.org/doi/10.1126/science.abj2258">hybrid immunity</a>, and other research has similarly found it provides better protection than natural infection alone.</p> <p>It also seems timing is important, as receiving a vaccine too soon after an infection (less than six months) appears to be <a href="https://www.nature.com/articles/s41598-023-50335-6">less effective</a> than getting vaccinated later.</p> <h2>What now?</h2> <p>Everyone’s immune system is slightly unique, and SARS-CoV-2 continues to mutate, so knowing exactly how long COVID immunity lasts is complicated.</p> <p>Evidence suggests immunity following infection should generally last six months in healthy adults, and can be prolonged with vaccination. But there are exceptions, and all of this assumes the virus has not mutated so much that it “escapes” our immune response.</p> <p>While many people feel the COVID pandemic is over, it’s important we don’t forget the lessons we have learned. Practices such as wearing a mask and staying home when unwell can reduce the spread of many viruses, not only <a href="https://www.bmj.com/content/375/bmj-2021-068302">COVID</a>.</p> <p>Vaccination is not mandatory, but for older adults eligible for a booster under the <a href="https://www.health.gov.au/news/atagi-update-on-the-covid-19-vaccination-program">current guidelines</a>, it’s a very good idea.<!-- Below is The Conversation's page counter tag.

It’s 4 years since the first COVID case in Australia. Here’s how our pandemic experiences have changed over time

<p><em><a href="https://theconversation.com/profiles/deborah-lupton-9359">Deborah Lupton</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>It might be hard to believe, but four years have now passed since the <a href="https://www.health.gov.au/topics/covid-19/about">first COVID case</a> was confirmed in Australia on January 25 2020. Five days later, the <a href="https://www.who.int/publications/m/item/covid-19-public-health-emergency-of-international-concern-(pheic)-global-research-and-innovation-forum">World Health Organization</a> (WHO) declared a “public health emergency of international concern”, as the novel coronavirus (later named SARS-CoV-2) began to spread worldwide.</p> <p>On March 11 the WHO would declare COVID a pandemic, while around the same time Australian federal and state governments hastily <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_departments/Parliamentary_Library/pubs/rp/rp2021/Chronologies/COVID-19StateTerritoryGovernmentAnnouncements">introduced measures</a> to “stop the spread” of the virus. These included shutting Australia’s international borders, closing non-essential businesses, schools and universities, and limiting people’s movements outside their homes.</p> <p>I began my project, <a href="https://www.frontiersin.org/articles/10.3389/fpubh.2023.1092322/full">Australians’ Experiences of COVID-19</a>, in May 2020. This research has continued each year to date, allowing me to track how Australians’ attitudes around COVID have changed over the course of the pandemic.</p> <h2>Evolving pandemic experiences</h2> <p>We recruited participants from across Australia, including people living in regional cities and towns. Participants range in age from early adulthood to people in their 80s.</p> <p>The first three stages of the project each involved 40 interviews with separate groups of participants (so 120 people in total). These interviews were done in May to July 2020 (stage 1), September to October 2021 (stage 2), and September 2022 (stage 3). Stage 4 was an online survey with 1,000 respondents, conducted in September 2023.</p> <p>Limitations of this project include the small sample sizes for the first three stages (as is common with qualitative interview-based research). This means the findings from those phases are not generalisable, but they do provide rich insights into the experiences of the interviewees. The quantitative stage 4 survey, however, is representative of the Australian population.</p> <p>The findings show that as the conditions of the pandemic and government management have changed across these years, so have Australians’ experiences.</p> <p>In the <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-021-10743-7">early months of the pandemic</a>, some people reported becoming confused, distressed and overwhelmed by the plethora of information sources and the fast-changing news environment. On the other hand, seeking out information provided reassurance and comfort in response to their anxiety and uncertainty about this new disease.</p> <p>Australians <a href="https://www.taylorfrancis.com/chapters/edit/10.4324/9781003280644-28/covid-19-crisis-communication-deborah-lupton">continued to rely heavily</a> on news reports and government announcements in the first two years of the pandemic. Regular briefings from premiers and <a href="https://theconversation.com/chief-health-officers-are-in-the-spotlight-like-never-before-heres-what-goes-on-behind-the-scenes-166828?utm_source=twitter&amp;utm_medium=bylinetwitterbutton">chief health officers in particular</a> were highly important for how they learned what was happening, as were updates in the media on case numbers, hospitalisations, deaths and progress towards vaccination targets.</p> <h2>Trust has eroded</h2> <p>Australians appear to have lost a lot of trust in COVID information sources such as news media reports, health agencies and government leaders. Early strong support of federal, state and territory governments’ pandemic management in <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-021-10743-7">2020</a> and <a href="https://www.tandfonline.com/doi/full/10.1080/14649365.2023.2240290">2021</a> has given way to much lower support more recently.</p> <p>My <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4626720">2023 survey</a> (this is published as a report, not peer-reviewed) found doctors were considered the most trustworthy sources of COVID information, but even they were trusted by only 60% of respondents.</p> <p>After doctors, participants trusted other experts in the field (53%), Australian government health agencies (52%), global health agencies (49%), scientists (45%) and community health organisations (35%). Australian government leaders were towards the lower end of the spectrum (31%).</p> <p>In <a href="https://academic.oup.com/heapro/article/38/1/daac192/7026242?login=false">2021</a>, Australians responded positively to the vaccine targets and “<a href="https://www.premier.vic.gov.au/victorias-roadmap-delivering-national-plan">road maps</a>” set by governments. These clear guidelines, and especially the promise that the initial doses would remove the need for lockdowns and border closures, were strong incentives to get vaccinated in 2021.</p> <p>Unfortunately, the prospect that vaccines would control COVID was shown to be largely unfounded. While COVID vaccines were and continue to be very effective at protecting against severe disease and death, they’re less effective at <a href="https://coronavirus.jhu.edu/vaccines/vaccines-faq">stopping people becoming infected</a>.</p> <p>Once very high numbers of eligible Australians became vaccinated against the delta variant, <a href="https://pubmed.ncbi.nlm.nih.gov/37068078/">omicron reached Australia</a>, resulting in Australia’s first big wave of infection. This led to disillusionment about vaccines’ value for many participants.</p> <p>In the <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4626720">2023 survey</a>, respondents reported a high uptake of the first three COVID shots. But when asked whether they planned to get another vaccine in the next 12 months, almost two-thirds said they did not, or they were unsure.</p> <h2>Enter complacency</h2> <p>Complacency now seems to have set in for many Australians. This can be linked to the progressive withdrawal of strong public health measures such as quarantine, mandatory isolation when infected, and testing and tracing regimens.</p> <p>Meanwhile, the media, government leaders and health agencies have played less of an active public role in conveying COVID information. This has led to uncertainty about the extent to which COVID is still a risk and lack of incentive to take protective actions such as mask wearing.</p> <p>In <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4626720">2023</a>, after mandates had ended, only 9% of respondents said they always wore a mask in indoor public places. Only a narrow majority of respondents even supported compulsory masking for workers in health-care facilities.</p> <p>The <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4626720">2023 survey</a> confirmed many Australians no longer feel at risk from COVID. Some 17% of respondents said COVID was definitely still posing a risk to Australians, while a further 42% saw COVID as somewhat of a risk. This left 28% who did not view COVID as much of a continuing risk, and 13% who thought it was not a risk at all.</p> <h2>COVID is still a risk</h2> <p>Whether or not people feel at continuing risk from COVID, the pandemic is still significantly affecting Australians. The <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4626720">2023 survey</a> found more than two-thirds of respondents (68%) reported having had at least one COVID infection to their knowledge, including 13% who had experienced three or more. Of those who’d had COVID, 40% said they experienced ongoing symptoms, or long COVID.</p> <p>If the pandemic loses visibility in public forums, people have no way of knowing the risk of infection continues, and are therefore unlikely to take steps to protect themselves and others.</p> <p>Updated case, hospitalisation, death and vaccination numbers should be communicated regularly, as <a href="https://theconversation.com/covid-is-surging-in-australia-and-only-1-in-5-older-adults-are-up-to-date-with-their-boosters-220839">used to be the case</a>. To combat confusion, complacency and misinformation, all health advice should be based on the latest robust science.</p> <p>Australians are operating in a vacuum of information from trusted sources. They need much better and more frequent public health campaigns and risk communication from their leaders.<!-- Below is The Conversation's page counter tag.

COVID is surging in Australia – and only 1 in 5 older adults are up to date with their boosters

<p><em><a href="https://theconversation.com/profiles/adrian-esterman-1022994">Adrian Esterman</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Do you have family members or friends sick with a respiratory infection? If so, there’s a good chance it’s COVID, caused by the JN.1 variant currently circulating in Australia.</p> <p>In particular, New South Wales is reportedly experiencing its <a href="https://www.abc.net.au/news/2024-01-09/nsw-sydney-covid-variant-virus-pandemic-hospitalisations/103298610">highest levels</a> of COVID infections in a year, while Victoria is said to be facing a “<a href="https://www.9news.com.au/national/victoria-in-midst-of-double-wave-of-covid19--as-jn1-triggers-infections-surge/4dada2cb-7d56-436a-9490-cad1d908a29a">double wave</a>” after a surge late last year.</p> <p>But nearly four years into the pandemic, data collection is less comprehensive than it was, and of course, fewer people are testing. So what do we know about the extent of this wave? And importantly, are we adequately protected?</p> <h2>Difficulties with data</h2> <p>Tracking COVID numbers was easier in the first half of last year, when each state and territory provided a weekly update, giving us data on case notifications, hospitalisations, ICU numbers and deaths.</p> <p>In the second half of the year some states and territories switched to less frequent reporting while others stopped their regular updates. As a result, different jurisdictions now report at different intervals and provide varying statistics.</p> <p>For example, <a href="https://www.health.vic.gov.au/infectious-diseases/victorian-covid-19-surveillance-report">Victoria</a> still provides weekly reports, while NSW publishes <a href="https://www.health.nsw.gov.au/Infectious/covid-19/Documents/respiratory-surveillance-20240106.pdf">fortnightly updates</a>.</p> <p>While each offer different metrics, we can gather – particularly from data on hospitalisations – that both states are experiencing a wave. We’re also seeing high levels of COVID <a href="https://www.health.vic.gov.au/infectious-diseases/victorian-covid-19-surveillance-report">in wastewater</a>.</p> <p>Meanwhile, <a href="https://health.nt.gov.au/covid-19/data">Northern Territory Health</a> simply tell you to go to the Australian government’s Department of Health website for COVID data. This houses the only national COVID <a href="https://www.health.gov.au/topics/covid-19/reporting?language=und">data collection</a>. Unfortunately, it’s not up to date, difficult to use, and, depending on the statistic, often provides no state and territory breakdowns.</p> <p>Actual case notifications are provided on a separate <a href="https://nindss.health.gov.au/pbi-dashboard/">website</a>, although given the lack of testing, these are likely to be highly inaccurate.</p> <p>The <a href="https://www.health.gov.au/topics/covid-19/reporting?language=und">Department of Health website</a> does provide some other data that gives us clues as to what’s happening. For example, as of one month ago, there were 317 active outbreaks of COVID in aged care homes. This figure has been generally rising since September.</p> <p>Monthly prescriptions for antivirals on the Pharmaceutical Benefits Scheme were increasing rapidly in November, but we are not given more recent data on this.</p> <p>It’s also difficult to obtain information about currently circulating strains. Data expert Mike Honey provides a regularly updated <a href="https://github.com/Mike-Honey/covid-19-genomes?tab=readme-ov-file#readme">snapshot</a> for Australia based on data from GISAID (the Global Initiative on Sharing All Influenza Data) that shows JN.1 rising in prevalence and accounting for about 40% of samples two weeks ago. The proportion is presumably higher now.</p> <h2>What’s happening elsewhere?</h2> <p>Many other countries are currently going through a COVID wave, probably driven to a large extent by JN.1. These include <a href="https://www.rnz.co.nz/news/national/506301/covid-19-complacency-waning-immunity-contribute-to-fifth-wave-epidemiologist">New Zealand</a>, <a href="https://www.independent.co.uk/news/world/europe/facemasks-mandatory-spain-hospitals-b2475563.html">Spain, Greece</a> and the United States.</p> <p>According to cardiologist and scientist Eric Topol, the US is currently experiencing its <a href="https://www.latimes.com/opinion/story/2024-01-04/covid-2024-flu-virus-vaccine">second biggest wave</a> since the start of the pandemic, linked to JN.1.</p> <h2>Are vaccines still effective?</h2> <p>It’s expected the current COVID vaccines, which target the omicron variant XBB.1.5, are still <a href="https://www.gavi.org/vaccineswork/seven-things-you-need-know-about-jn1-covid-19-variant">effective</a> at reducing hospitalisations and deaths from JN.1 (also an omicron offshoot).</p> <p>The Australian Technical Advisory Group on Immunisation (ATAGI) updated their <a href="https://www.health.gov.au/news/atagi-update-on-the-covid-19-vaccination-program">advice</a> on booster shots in September last year. They recommended adults aged over 75 should receive an additional COVID vaccine dose in 2023 if six months had passed since their last dose.</p> <p>They also suggest all adults aged 65 to 74 (plus adults of any age who are severely immunocompromised) should consider getting an updated booster. They say younger people or older adults who are not severely immunocompromised and have already had a dose in 2023 don’t need further doses.</p> <p>This advice is very confusing. For example, although ATAGI does not recommend additional booster shots for younger age groups, does this mean they’re not allowed to have one?</p> <p>In any case, as of <a href="https://www.health.gov.au/resources/publications/covid-19-vaccine-rollout-update-8-december-2023?language=en">December 6</a>, only 19% of people aged 65 and over had received a booster shot in the last six months. For those aged 75 and over, this figure is 23%. Where is the messaging to these at-risk groups explaining why updating their boosters is so important?</p> <h2>Should we be concerned by this wave?</h2> <p>That depends on who we mean by “we”. For those who are vulnerable, absolutely. Mainly because so few have received an updated booster shot and very few people, including the elderly, are wearing masks.</p> <p>For the majority of people, a COVID infection is unlikely to be serious. The biggest concern for younger people is the risk of long COVID, which research suggests <a href="https://www.nature.com/articles/s41591-022-02051-3">increases</a> with each reinfection.</p> <h2>What should we expect in 2024?</h2> <p>It’s highly likely we will see repeated waves of infections over the next 12 months and beyond, mainly caused by waning immunity from previous infection, vaccination or both, and new subvariants.</p> <p>Unless a new subvariant causes more severe disease (and at this stage, there’s no evidence JN.1 does), we should be able to manage quite well, without our hospitals becoming overwhelmed. However, we should be doing more to protect our vulnerable population. Having only one in five older people up to date with a booster and more than 300 outbreaks in aged care homes is not acceptable.</p> <p>For those who are vulnerable, the usual advice applies. Make sure you’re up to date with your booster shots, wear a P2/N95 mask when out and about, and if you do get infected, take antivirals as soon as possible.<!-- Below is The Conversation's page counter tag.

I have COVID. How likely am I to get long COVID?

Eris, along with other circulating strains, are descendants of Omicron.</p> <p>While these strains appear less severe than the original Alpha and Delta variants, the risk of long COVID remains.</p> <p>So what does the latest data say about the chance of long COVID? What symptoms should you look out for? And what can be done to support people with long COVID?</p> <h2>When COVID becomes ‘long COVID’</h2> <p>For most people, long COVID means not getting better after a COVID infection.</p> <p>The World Health Organization <a href="https://www.who.int/publications-detail-redirect/WHO-2019-nCoV-Post_COVID-19_condition-Clinical_case_definition-2021.1">defines long COVID</a> as continuing or new symptoms at least three months from the start of a COVID infection that last at least two months and cannot be explained by an alternative diagnosis.</p> <p>The most <a href="https://link.springer.com/article/10.1007/s10654-022-00962-6">common symptoms</a> include fatigue, brain fog, breathlessness, headaches and abdominal pain. But people with long COVID can experience <a href="https://www.sciencedirect.com/science/article/pii/S1684118222001864?via%3Dihub">a wide range</a> of problems including cardiovascular issues, mental health problems such as depression and anxiety, insomnia, muscle and joint pain, and gastrointestinal problems.</p> <h2>How common is long COVID?</h2> <p>Australian data on long COVID <a href="https://www.mja.com.au/journal/2023/218/10/long-covid-australia-achieving-equitable-access-supportive-health-care">remains limited</a> compared to <a href="https://www150.statcan.gc.ca/n1/pub/75-006-x/2023001/article/00015-eng.htm">international data</a>, and estimates of its prevalence have varied. A report from Australia’s parliamentary inquiry into long COVID, <a href="https://parlinfo.aph.gov.au/parlInfo/download/committees/reportrep/RB000006/toc_pdf/SickandtiredCastingalongshadow.pdf">published in April</a>, suggested 2%-20% of people may develop long COVID following an infection.</p> <p>A recent Australian study conducted when vaccines were widely available indicates earlier Omicron variants <a href="https://doi.org/10.3390/ijerph20186756">saw 10% of people</a> who caught COVID develop long COVID.</p> <p>Another recent study, yet to be peer-reviewed, found <a href="https://www.medrxiv.org/content/10.1101/2023.08.06.23293706v1">18.2%</a> of those infected went on to have long COVID. The wide-ranging estimates are likely to be because of different COVID variants, differences in vaccination, and different long COVID definitions and assessment methods.</p> <p>The risk is lower in children. One Australian study indicated persistent symptoms in <a href="https://www.thelancet.com/journals/lanchi/article/PIIS2352-4642(21)00124-3/fulltext">8% of children</a> who had COVID in 2020, while <a href="https://www.medrxiv.org/content/10.1101/2023.03.14.23287239v1">preliminary research</a> points to a slightly lower risk among children infected in 2021.</p> <p>But more research is needed, especially as the virus continues to evolve. This can be complicated because typical long COVID symptoms are common to many other health problems. As in other countries, more research is now underway <a href="https://www.apprise.org.au/broad-research-area/insights-into-long-covid/">in Australia</a> to determine the accurate prevalence of the condition using a definition and methods that carefully exclude other causes.</p> <p>Although research on long COVID risk factors with new variants is ongoing, we expect being female, having more severe initial disease and having other health conditions will <a href="https://doi.org/10.1001/jamainternmed.2023.0750">increase a person’s chance</a> of getting long COVID.</p> <h2>What’s different this time?</h2> <p>Research shows COVID vaccines offer <a href="https://www.mdpi.com/1660-4601/19/19/12422">protection</a> against long COVID. As well as vaccinations, immunity from previous COVID infections and antiviral treatments are contributing to less severe COVID and potentially <a href="https://theconversation.com/could-antivirals-reduce-your-risk-of-long-covid-where-the-research-is-up-to-on-prevention-and-treatment-216529">less long COVID</a> than we saw earlier in the pandemic.</p> <p>But while the Omicron waves may lead to <a href="https://www.smh.com.au/national/newer-virus-strains-less-likely-to-cause-long-covid-20231123-p5emag.html">fewer cases of long COVID</a> than the earlier Alpha and Delta variants, because so many Australians are contracting COVID, this will still result in a large number of people with long COVID. And each <a href="https://www150.statcan.gc.ca/n1/pub/75-006-x/2023001/article/00015-eng.htm">repeat infection</a> presents a new risk of prolonged symptoms.</p> <h2>Long COVID can affect all aspects of life</h2> <p>Long COVID can <a href="https://doi.org/10.1093/ije/dyad033">impact</a> a person’s life in many ways. Fatigue following exertion, brain fog and other symptoms can reduce capacity to perform tasks such as concentrating at a computer, manual labour, and even normal household tasks.</p> <p>Many people with long COVID submitted evidence to the recent <a href="https://www.aph.gov.au/Parliamentary_Business/Committees/House/Health_Aged_Care_and_Sport/LongandrepeatedCOVID/Report/Chapter_4_-_Lived_experiences_of_long_COVID">parliamentary inquiry</a> that they were unsupported, stigmatised, isolated, and not taken seriously by health professionals.</p> <p>Evidence suggests many symptoms <a href="https://www.thelancet.com/journals/lanepe/article/PIIS2666-77622200250-2/fulltext">will improve</a> in most people over <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(23)00138-4/fulltext">12 to 18 months</a>, although recovery time can differ between symptoms. Some, including gastrointestinal and respiratory symptoms, tend to <a href="https://www.nature.com/articles/s41579-022-00846-2">resolve sooner than others</a>, such as cognitive symptoms.</p> <h2>I think I have long COVID, what can I expect from my doctor?</h2> <p>Long COVID is the kind of challenge Australia’s <a href="https://dx.doi.org/10.5694/mja2.51950">health system finds most difficult</a>. GPs are stretched and the small number of specialist <a href="https://www.abc.net.au/news/2023-12-12/long-covid-clinics-are-closing-as-us-clinic-expands/103186272">long COVID clinics</a> are struggling to maintain funding.</p> <p>Australia has trailed behind the US, the UK and Europe in rolling out care for long COVID, and in collecting data on the condition.</p> <p>As a result, support for long COVID in Australia is <a href="https://doi.org/10.3389/phrs.2023.1606084">hard to access</a>, expensive and patchy.</p> <p>However, there is consensus on what constitutes good care. Clinicians seeing patients with possible long COVID should:</p> <ul> <li> <p>validate the person’s experience of symptoms and the impact their symptoms are having on their functioning, particularly when the cause is not clear</p> </li> <li> <p>diagnose and treat any other health conditions that are part of the picture</p> </li> <li> <p>support people to minimise the impairment their symptoms cause by pacing of physical and cognitive activities. Importantly, this doesn’t involve pushing through fatigue.</p> </li> </ul> <p>These steps are not a cure but they may improve a person’s ability to function in their day-to-day life, at work and to fulfil their caring responsibilities.</p> <h2>We still need to focus on reducing COVID transmission</h2> <p>The best way to prevent long COVID is to avoid contracting – and spreading – COVID. This means:</p> <ul> <li> <p>getting vaccinated or boosted, if you’re eligible</p> </li> <li> <p>staying home if you feel unwell</p> </li> <li> <p>wearing a mask to protect yourself and vulnerable community members</p> </li> <li> <p>testing for COVID if you have symptoms and if you test positive, taking antivirals (if eligible) and isolating until your symptoms resolve.</p> </li> </ul> <p>Long COVID is not going away, but we all have a role to play in preventing and responding to it.</p> <p><em>Ruby Biezen from the APPRISE Network and the University of Melbourne and Andrew Lloyd from the Kirby Institute at UNSW contributed to this article.</em><!-- Below is The Conversation's page counter tag.

COVID wave: what’s the latest on antiviral drugs, and who is eligible in Australia?

<p><em><a href="https://theconversation.com/profiles/jessica-pace-1401278">Jessica Pace</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Australia is experiencing a <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">fresh wave of COVID</a>, seeing increasing cases, more hospitalisations and a greater number of prescriptions for COVID antivirals dispensed over recent months.</p> <p>In the early days of the pandemic, the only medicines available were those that treated the symptoms of the virus. These included steroids and analgesics such as paracetamol and ibuprofen to treat pain and fever.</p> <p>We now have two drugs called <a href="https://www.health.wa.gov.au/%7E/media/Corp/Documents/Health-for/Infectious-disease/COVID19/Treatment/COVID19-PAXLOVID-Patient-information.pdf">Paxlovid</a> and <a href="https://www.sahealth.sa.gov.au/wps/wcm/connect/abefa4a4-ecaa-4c26-8713-d80c90388545/COVID-19+Treatment+Fact+Sheet+-+Molnupiravir+-+Prescribers+20220428.pdf?MOD=AJPERES&amp;CACHEID=ROOTWORKSPACE-abefa4a4-ecaa-4c26-8713-d80c90388545-oIRWpvB">Lagevrio</a> that treat the virus itself.</p> <p>But are these drugs effective against current variants? And who is eligible to receive them? Here’s what to know about COVID antivirals as we navigate this <a href="https://www.smh.com.au/national/a-slightly-more-dangerous-place-australia-is-in-its-eighth-covid-wave-20231030-p5eg5k.html">eighth COVID wave</a>.</p> <h2>What antivirals are available?</h2> <p><a href="https://www.tga.gov.au/resources/artg/389801">Paxlovid</a> is a combination of two different drug molecules, nirmatrelvir and ritonavir. The nirmatrelvir works by blocking an enzyme called a protease that the virus needs to replicate. The ritonavir is included in the medicine to protect the nirmatrelvir, stopping the body from breaking it down.</p> <p>Molnupiravir, marketed as <a href="https://www.tga.gov.au/resources/artg/372650">Lagevrio</a>, works by forcing errors into the RNA of SARS-CoV-2 (the virus that causes COVID) as it replicates. As these errors build up, the virus becomes less effective.</p> <p>This year in Australia, the <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">XBB COVID strains</a> have dominated, and acquired a couple of key mutations. When COVID mutates into new variants, it doesn’t affect the ability of either Paxlovid or Lagevrio to work because the parts of the virus that change from the mutations aren’t those targeted by these two drugs.</p> <p>This is different to the <a href="https://app.magicapp.org/#/guideline/L4Q5An/section/E8kMVn">monoclonal antibody-based medicines</a> that were developed against specific strains of the virus. These drugs are not thought to be effective for any variant of the virus <a href="https://www.who.int/activities/tracking-SARS-CoV-2-variants">from omicron XBB.1.5 onwards</a>, which includes the current wave. This is because these drugs recognise certain proteins expressed on the surface of SARS-CoV-2, which have changed over time.</p> <h2>What does the evidence say?</h2> <p>As Lagevrio and Paxlovid are relatively new medicines, we’re still learning how well they work and which patients should use them.</p> <p>The latest <a href="https://app.magicapp.org/#/guideline/L4Q5An/section/L0OPkj">evidence</a> suggests Paxlovid decreases the risk of hospitalisation if taken early by those at <a href="https://www.nsw.gov.au/covid-19/testing-managing/antivirals">highest risk of severe disease</a>.</p> <p>Results from <a href="https://www.nejm.org/doi/10.1056/NEJMoa2116044">a previous trial</a> suggested Lagevrio might reduce COVID deaths. But a more recent, <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4237902">larger trial</a> indicated Lagevrio doesn’t significantly reduce hospitalisations or deaths from the virus.</p> <p>However, few people at highest risk from COVID were included in this trial. So it could offer some benefit for patients in this group.</p> <p>In Australia, Lagevrio is not routinely <a href="https://app.magicapp.org/#/guideline/L4Q5An/section/L0OPkj">recommended</a> and Paxlovid is preferred. However, not all patients can take Paxlovid. For example, people with medical conditions such as <a href="https://www.paxlovidhcp.com/moderate-renal-impairment">severe kidney or liver impairment</a> shouldn’t take it because these issues can affect how well the body metabolises the medication, which increases the risk of side effects.</p> <p>Paxlovid also can’t be taken alongside some <a href="https://www.cec.health.nsw.gov.au/__data/assets/pdf_file/0020/702821/Information-for-patients-family-and-carers-nirmatrelvir-and-ritonavir.PDF">other medications</a> such as those for certain heart conditions, mental health conditions and cancers. For high-risk patients in these cases, Lagevrio can be considered.</p> <p>Some people who take COVID antivirals will experience side effects. Mostly these are not serious and will go away with time.</p> <p>Both <a href="https://www.cec.health.nsw.gov.au/__data/assets/pdf_file/0020/702821/Information-for-patients-family-and-carers-nirmatrelvir-and-ritonavir.PDF">Paxlovid</a> and <a href="https://www.cec.health.nsw.gov.au/__data/assets/pdf_file/0008/702818/Information-for-patients-family-and-carers-molnupiravir.PDF">Lagevrio</a> can cause diarrhoea, nausea and dizziness. Paxlovid can also cause side effects including muscle aches and weakness, changes in taste, loss of appetite and abdominal pain. If you experience any of these, you should contact your doctor.</p> <p>More serious side effects of both medicines are allergic reactions, such as shortness of breath, swelling of the face, lips or tongue and a severe rash, itching or hives. If you experience any of these, call 000 immediately or go straight to the nearest emergency department.</p> <h2>Be prepared</h2> <p>Most people will be able to manage COVID safely at home without needing antivirals. However, those at higher risk of severe COVID and therefore <a href="https://www.nsw.gov.au/covid-19/testing-managing/antivirals#:%7E:text=Both%20are%20available%20in%20NSW,Lagevrio%C2%AE%20(molnupiravir)launch.">eligible for antivirals</a> should seek them. This includes people aged 70 or older, people aged 50 or older or Aboriginal people aged 30 or older with one additional risk factor for severe illness, and people 18 or older who are immunocompromised.</p> <p>If you are in any of these groups, it’s important you <a href="https://www.health.nsw.gov.au/Infectious/covid-19/Documents/translated/plan-ahead-covid-flu-english.pdf">plan ahead</a>. Speak to your health-care team now so you know what to do if you get COVID symptoms.</p> <p>If needed, this will ensure you can start treatment as soon as possible. It’s important antivirals are started within <a href="https://www.nsw.gov.au/covid-19/testing-managing/antivirals#:%7E:text=Both%20are%20available%20in%20NSW,Lagevrio%C2%AE%20(molnupiravir)launch.">five days of symptom onset</a>.</p> <p>If you’re a high-risk patient and you test positive, contact your doctor straight away.

Should we still be using RATs to test for COVID? 4 key questions answered

<p><em><a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>We’re currently navigating <a href="https://www.thenewdaily.com.au/life/health/2023/11/15/covid-australia-eighth-wave">an eighth wave</a> of <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">COVID infections</a> in Australia. However the threat COVID poses to us is significantly less than it has ever been, thanks to immunity we’ve acquired through <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(22)00801-5/fulltext">a combination</a> of prior infection and vaccination.</p> <p>That said, COVID is by no means behind us. The threat of severe illness remains higher for many people, and we’re all potentially at risk of developing <a href="https://www.health.gov.au/topics/covid-19/long-covid">long COVID</a>.</p> <p>While many people appear to be doing fewer rapid antigen tests (RATs) than they used to – if any at all – with rising cases, and as we head towards the festive season, testing continues to be important.</p> <p>So what do you need to know about testing in this wave? Here are four key questions answered.</p> <h2>1. When should I do a RAT?</h2> <p>There are a few situations where determining your COVID status is important to inform your actions, particularly during an uptick in infections. With more circulating virus, your index of suspicion that you have COVID if you’re experiencing cold-like symptoms should be higher.</p> <p>RATs work best when they’re used to confirm whether you have COVID when you <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/how-testing-works-covid-19">have respiratory symptoms</a> and are infectious. So the primary use of RATs should be to determine your COVID status when you’re sick. A positive test should prompt you to isolate, and if you’re eligible, to seek antivirals.</p> <p>Testing might also be worthwhile if you’ve come into contact with someone with COVID but you haven’t developed symptoms. If you find you have in fact contracted the virus, you can take steps to avoid spreading it to other people (you can infect others even <a href="https://www.healthline.com/health/what-is-asymptomatic-covid#prevalence">when you’re asymptomatic</a>). This is especially important if you’re going to be socialising in large groups or in contact with people who are vulnerable.</p> <p>Another situation in which to consider testing, particularly at this time of year, is before attending large social gatherings. While the reliability of a RAT is never perfect, do the test as close to the event as possible, because your disease status <a href="https://www.businessinsider.com/omicron-rapid-test-hour-before-party-not-day-before-expert-2021-12">can change quickly</a>.</p> <h2>2. Should I test multiple times?</h2> <p>Yes. RATs are not as sensitive as PCR tests, which is the trade-off we make for being able to do this test at home and <a href="https://www.wsj.com/articles/public-health-officials-pursue-covid-19-tests-that-trade-precision-for-speed-11599562800">getting a rapid result</a>.</p> <p>This means that while if you test positive with a RAT you can be very confident you have COVID, if you test negative, you cannot be as confident that you don’t have COVID. That is, the test may give you a false negative result.</p> <p>Although RATs from different manufacturers have different accuracies, all RATs approved by Australia’s Therapeutic Goods Administration must have a sensitivity of <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia#:%7E:text=For%20rapid%20antigen%20tests%2C%20this,specificity%20of%20at%20least%2098%25.">at least 80%</a>.</p> <p>The way to increase your confidence in a negative result is to do multiple RATs serially – each negative test increases the confidence you can have that you don’t have COVID. If you have symptoms and have tested negative after your first RAT, <a href="https://www.fda.gov/medical-devices/safety-communications/home-covid-19-antigen-tests-take-steps-reduce-your-risk-false-negative-results-fda-safety">the advice</a> is to repeat the test after 48 hours, and potentially a third time after another 48 hours if the second test is also negative.</p> <h2>3. Do RATs detect the latest variants?</h2> <p>Since RATs <a href="https://www.healthdirect.gov.au/covid-19/testing#:%7E:text=Rapid%20antigen%20tests%2C%20or%20RATs,of%20proteins%20of%20the%20virus.">detect particular surface proteins</a> on SARS-CoV-2 (the virus that causes COVID), it’s theoretically possible that as the virus evolves, the reliability of these tests may be affected.</p> <p>However, RATs were designed to detect a part of the virus that is not as likely to mutate, so the hope is these tests <a href="https://www.health.com/do-covid-tests-work-new-variants-7967102">will continue to hold up</a> as SARS-CoV-2 evolves.</p> <p>The performance of RATs is continually being assessed by manufacturers. So far, there’s been no change reported in the ability of these tests to <a href="https://www.ama.com.au/articles/tga-updated-advice-rats-nearing-expiry-and-rats-efficacy-current-strains#:%7E:text=The%20TGA%20has%20received%20evidence,19%20RAT%20post%2Dmarket%20review.">detect the latest variants</a>.</p> <h2>4. Can I rely on expired RATs?</h2> <p>At this point in the pandemic, you might have a few expired tests at the back of your cupboard.</p> <p>Technically the most appropriate advice is to say you should never use a diagnostic test <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia">past its expiry date</a>. As a general principle the performance of a test cannot be guaranteed beyond this date. The risk is that over time the components of the RAT degrade and if you use a test that’s not working optimally, it’s more likely to indicate <a href="https://www.health.com/can-you-use-expired-covid-test-6827970">you don’t have COVID</a> when you actually do, which may have consequences.</p> <p>However, as for all things COVID, the answer is not so black and white. Since these tests were new when they were introduced earlier in the pandemic, manufacturers didn’t have specific data on their performance over time, and so the expiry dates given were necessarily conservative.</p> <p>It’s likely these tests will work beyond the expiry dates on the packet, but just how long and how well they work is a bit of an unknown, so we need to be cautious.</p> <p>The other thing to consider is ensuring you store RATs correctly. Storage instructions should be found on the packet, but the key issue is making sure they’re not exposed to extreme temperatures. In particular, <a href="https://7news.com.au/lifestyle/health-wellbeing/how-to-properly-store-your-at-home-covid-19-rapid-antigen-tests-c-5465412">high temperatures</a> may damage the chemicals in the test which may reduce its sensitivity.</p> <h2>The path from here</h2> <p>Regular upticks in COVID cases are something we’re going to have to get used to. At these times, we should all be a bit more cautious about looking after ourselves and others as we go about our lives. What this looks like will vary for different people depending on their personal circumstances.</p> <p>However, being up to date with <a href="https://theconversation.com/what-are-the-new-covid-booster-vaccines-can-i-get-one-do-they-work-are-they-safe-217804">booster vaccinations</a>, having a plan for <a href="https://www.health.gov.au/topics/covid-19/oral-treatments">accessing antivirals</a> if you’re eligible, <a href="https://theconversation.com/with-covid-surging-should-i-wear-a-mask-217902">wearing masks</a> in high-risk settings and testing all continue to play an important role in responding to COVID.<!-- Below is The Conversation's page counter tag.

With COVID surging, should I wear a mask?

<p><em><a href="https://theconversation.com/profiles/c-raina-macintyre-101935">C Raina MacIntyre</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>COVID is <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">on the rise again</a>, with a peak likely over the holiday season.</p> <p>Given this, health authorities in a number of Australian states have recommended people start <a href="https://www.thenewdaily.com.au/life/health/2023/11/15/covid-australia-eighth-wave">wearing masks again</a>. In <a href="https://www.abc.net.au/news/2023-11-17/wa-public-hospitals-mask-requirements-roger-cook-covid-19/103120580">Western Australia</a>, masks have been made mandatory in high-risk areas of public hospitals, while they’ve similarly been reintroduced in health-care settings in <a href="https://www.adelaidenow.com.au/coronavirus/mandatory-face-masks-introduced-in-lyell-mcewin-and-modbury-hospitals-as-covid-wave-hits-sa/news-story/b4bad98deb02a66dde4cf866f60b607a">other parts of the country</a>.</p> <p>Hospitals and aged care facilities are definitely the first places where masks need to be reinstated during an epidemic. But authorities are <a href="https://www.thenewdaily.com.au/life/health/2023/11/15/covid-australia-eighth-wave">differing in their recommendations</a> currently. Calls to mask up, particularly in the wider community, <a href="https://www.9news.com.au/national/queensland-covid-chief-health-officer-confirms-covid-wave/a3a92381-bd6f-4175-a366-3b8e0f627990">have not been unanimous</a>.</p> <p>So amid rising COVID cases, should you be wearing a mask?</p> <h2>COVID is still a threat</h2> <p>Unfortunately, SARS-CoV-2 (the virus that causes COVID) has not mutated into just a trivial cold.</p> <p>As well as causing symptoms in the initial phase – which can be especially serious for people who are vulnerable – the virus can lead to <a href="https://www.nature.com/articles/s41579-022-00846-2">chronic illness</a> in people of any age and health status due to its ability to affect blood vessels, <a href="https://academic.oup.com/eurheartjsupp/article/25/Supplement_A/A42/7036729">the heart</a>, lungs, brain and immune system.</p> <p>COVID and its ongoing effects are contributing to <a href="https://www.nature.com/articles/s41591-023-02521-2">substantial disability</a> in society. Loss of productivity due to long COVID is affecting <a href="https://www.mckinsey.com/industries/healthcare/our-insights/one-billion-days-lost-how-covid-19-is-hurting-the-us-workforce">workforce and economies</a>.</p> <p>While public messaging to “live with COVID” has seemingly encouraged us to move on from the pandemic, SARS-CoV-2 has other ideas. It has <a href="https://erictopol.substack.com/p/the-virus-is-learning-new-tricks">continued to mutate</a>, become <a href="https://www.ebgtz.org/resource/omicron-faqs/">more contagious</a>, and to evade the protection offered by vaccines.</p> <p>COVID is not endemic, but is <a href="https://www.cnbc.com/2022/02/02/covid-will-never-become-an-endemic-virus-scientist-warns.html">an epidemic virus</a> like influenza or measles, so we can expect waves to keep coming. With this in mind, it’s definitely worth protecting yourself – particularly when cases are rising.</p> <h2>What can we do to protect ourselves?</h2> <p>We know SARS-CoV-2 transmits <a href="https://www.thelancet.com/article/S0140-6736(21)00869-2/fulltext">through the air</a> we breathe. We also know a lot of the transmission risk is <a href="https://abcnews.go.com/Health/covid-transmission-asymptomatic/story?id=84599810">from people without symptoms</a>, so you can’t tell who around you is infectious. This provides a strong rationale for universal masking during periods of high transmission.</p> <p>The need is highest in hospitals where thousands of unsuspecting patients have caught COVID during the course of the pandemic and <a href="https://www.theage.com.au/national/victoria/a-death-sentence-more-than-600-people-die-after-catching-covid-in-hospital-20230621-p5di7x.html">hundreds have died</a> as a result in Victoria alone. Aged care facilities are similarly vulnerable.</p> <p>Masks <a href="https://theconversation.com/yes-masks-reduce-the-risk-of-spreading-covid-despite-a-review-saying-they-dont-198992">do work</a>. A Cochrane review suggesting they don’t was flawed and subject to <a href="https://www.thestar.com/news/canada/how-the-cochrane-review-went-wrong-report-questioning-covid-masks-blows-up-prompts-apology/article_80b67196-5872-5b1a-a208-b0a525f8de5b.html">an apology</a>.</p> <p>Masks work equally by protecting others and protecting you. By visualising human exhalations too tiny to see with the naked eye, my colleagues and I showed how masks <a href="https://theconversation.com/which-mask-works-best-we-filmed-people-coughing-and-sneezing-to-find-out-143173">prevent outward emissions</a> and how each layer of a mask improves this.</p> <p>The most protective kind of mask is <a href="https://theconversation.com/time-to-upgrade-from-cloth-and-surgical-masks-to-respirators-your-questions-answered-174877">a respirator or N95</a>, but any mask protects <a href="https://www.cdc.gov/mmwr/volumes/71/wr/mm7106e1.htm">more than no mask</a>.</p> <p>Wearing a mask when visiting health-care or aged-care facilities is important. Wearing a mask at the shops, on public transport and in other crowded indoor settings will improve your chances of having a COVID-free Christmas.</p> <h2>What about vaccines?</h2> <p>Although the virus’ evolution has challenged vaccines, they remain very important. Boosters will improve protection because vaccine immunity wanes and new mutations make older vaccines less effective.</p> <p>In May 2023 the <a href="https://www.who.int/news/item/18-05-2023-statement-on-the-antigen-composition-of-covid-19-vaccines">World Health Organization</a> outlined why <a href="https://erictopol.substack.com/p/the-ba286-variant-and-the-new-booster">monovalent boosters</a> matched to a single current circulating strain gives better protection than the old bivalent boosters (which target two strains). The XBB boosters are available <a href="https://www.sbs.com.au/news/article/the-covid-19-vaccines-australians-cant-get-yet/ueac5puue">in the United States</a>, and will be available in Australia <a href="https://www.health.gov.au/ministers/the-hon-mark-butler-mp/media/new-covid-19-vaccines-available-to-target-current-variants?language=en">from December 11</a>.</p> <p>Testing and treatment will also help. There are effective antivirals for COVID, but you cannot get them without a COVID test, and <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">testing rates</a> are very low. Having some RAT tests on hand means you can quickly isolate and get antivirals if indicated.</p> <p>Finally, safe indoor air is key. Remember that SARS-CoV-2 spreads silently, mainly by inhaling contaminated air. Opening a window or using an air purifier can significantly reduce your risk, especially in crowded indoor settings <a href="https://iopscience.iop.org/article/10.1088/2752-5309/ace5c9">like schools</a>. A <a href="https://ozsage.org/media_releases/">multi-layered strategy</a> of vaccines, masks, safe indoor air, testing and treatment will help us navigate this COVID wave.</p> <hr /> <p><em>Editor’s note: This article has been updated to reflect the announcement that monovalent XBB 1.5 vaccines will be deployed as part of Australia’s COVID vaccination program.<!-- Below is The Conversation's page counter tag.

A primary course is not recommended for children aged six months to five years <em>without</em> additional risk factors.</p> <h2>Monovalent, bivalent? What’s the difference?</h2> <p><strong>From monovalent</strong></p> <p>The initial COVID vaccines were “monovalent”. They had one target – the original viral strain.</p> <p>But as the virus mutated, we assigned new letters of the Greek alphabet to each variant. This brings us to Omicron. With this significant change, we saw “immune evasion”. The virus had changed so much the original vaccines didn’t provide sufficient immunity.</p> <p><strong>To bivalent</strong></p> <p>So vaccines were updated to target an early Omicron subvariant, BA.1, plus the original ancestral strain. With two targets, these were the first of the “bivalent” vaccines, which were approved in Australia <a href="https://theconversation.com/omicron-specific-vaccines-may-give-slightly-better-covid-protection-but-getting-boosted-promptly-is-the-best-bet-190736">in 2022</a>.</p> <p>Omicron continued to evolve, leading to more “immune escape”, contributing to repeated waves of transmission.</p> <p>The vaccines were updated again in <a href="https://theconversation.com/havent-had-covid-or-a-vaccine-dose-in-the-past-six-months-consider-getting-a-booster-199096">early 2023</a>. These newer bivalent vaccines target two strains – the ancestral strain plus the subvariants BA.4 and BA.5.</p> <p><strong>Back to monovalent</strong></p> <p>Further changes in the virus have meant our boosters needed to be updated again. This takes us to the recent announcement.</p> <p>This time the booster targets another subvariant of Omicron known as XBB.1.5 (sometimes known as <a href="https://theconversation.com/the-kraken-subvariant-xbb-1-5-sounds-scary-but-behind-the-headlines-are-clues-to-where-covids-heading-198158">Kraken</a>).</p> <p>This vaccine is monovalent once more, meaning it has only one target. The target against the original viral strain has been removed.</p> <p>According to advice given to the World Health Organization <a href="https://www.who.int/news/item/18-05-2023-statement-on-the-antigen-composition-of-covid-19-vaccines">in May</a>, this is largely because immunity to this original strain is no longer required (it’s no longer infecting humans). Raising immunity to the original strain may also hamper the immune response to the newer component, but we’re not sure if this is occurring or how important this is.</p> <p>The United States <a href="https://theconversation.com/cdc-greenlights-two-updated-covid-19-vaccines-but-how-will-they-fare-against-the-latest-variants-5-questions-answered-213341">approved</a> XBB.1.5-specific vaccines from Pfizer and Moderna in <a href="https://www.fda.gov/news-events/press-announcements/fda-takes-action-updated-mrna-covid-19-vaccines-better-protect-against-currently-circulating">mid-September</a>.

This variant is the one causing high numbers of cases around the world currently, including in Australia. It is very similar to the XBB version contained in the updated booster.</p> <p>The updated vaccines should also cover <a href="https://theconversation.com/how-evasive-and-transmissible-is-the-newest-omicron-offshoot-ba-2-86-that-causes-covid-19-4-questions-answered-212453">BA.2.86 or Pirola</a>, according to <a href="https://www.tga.gov.au/sites/default/files/2023-10/auspar-spikevax-xbb.1.5-231012.pdf">early results</a> from clinical trials and the US <a href="https://www.cdc.gov/respiratory-viruses/whats-new/covid-19-variant.html">Centers for Disease Control</a>.

So performance of these vaccines against new variants will continue to be closely monitored.</p> <h2>Are they safe?</h2> <p>The <a href="https://www.ebs.tga.gov.au/ebs/picmi/picmirepository.nsf/pdf?OpenAgent=&amp;id=CP-2023-PI-02409-1&amp;d=20231117172310101">safety</a> of the updated vaccines has also been shown to be similar to previous versions. Studies <a href="https://www.medrxiv.org/content/10.1101/2023.08.22.23293434v2">comparing them</a> found no significant difference in terms of the adverse events reported.</p> <p>Given the availability of the updated vaccines, some countries have removed their approval for earlier versions. This is because newer versions are a closer match to currently circulating strains, rather than any safety issue with the older vaccines.</p> <h2>What happens next?</h2> <p>The availability of updated vaccines is a welcome development, however this is not the end of the story. We need to make sure eligible people get vaccinated.</p> <p>We also need to acknowledge that vaccination should form part of a comprehensive strategy to limit the impact of COVID from now on. That includes measures such as mask wearing, social distancing, focusing on ventilation and air quality, and to a lesser degree hand hygiene. Rapidly accessing antivirals if eligible is also still important, as is keeping away from others if you are infected.<!-- Below is The Conversation's page counter tag.

Not all beer and pokies: what Australians did with their super when COVID struck

They withdrew <a href="https://www.apra.gov.au/covid-19-early-release-scheme-issue-36">$36 billion</a>.</p> <p>Most of those surveyed by the Institute of Family Studies said they used the money to cover <a href="https://aifs.gov.au/sites/default/files/publication-documents/2108_6_fias_superannuation_0.pdf">immediate expenses</a>. But definitions of “immediate” can vary.</p> <p>Real time transaction card data appeared to show early withdrawers boosted their spending by an average of <a href="https://www.illion.com.au/buy-now-pay-later-winner-of-stimulus/">$3,000</a> in the fortnight after they got the money.</p> <p><a href="https://www.stptax.com/emergency-super-withdrawal-spent-on-pokies-beer-and-uber-eats/">One interpretation</a> said they spent the money on “beer, wine, pokies, and takeaway food, rather than mortgages, bills, car debts, and clothes”.</p> <p>In order to get a more complete picture, we obtained access to millions of anonymised transaction records of customers of Australia’s largest bank, the <a href="https://www.sciencedirect.com/science/article/pii/S0313592622001060?via%3Dihub#bfn3">Commonwealth Bank</a>.</p> <p>The data included 1.54 million deposits likely to have been money withdrawn through the scheme including 1.04 million we are fairly confident did.</p> <h2>Who dipped into super?</h2> <p>The data provided by the bank allows us to compare circumstances of withdrawers and non-withdrawers including their age, time with the bank, and banking behaviour before COVID.</p> <p>We find withdrawers tended to be younger and in poorer financial circumstances than non-withdrawers before the pandemic. Six in ten of the withdrawers were under the age of 35, a finding consistent with data reported by the <a href="https://www.abc.net.au/news/2020-05-25/coronavirus-early-access-superannuation-young-people/12282546">Australian Taxation Office</a>.</p> <p>Withdrawers tended to earn less than non-withdrawers, even non-withdrawers of the same age. Only 17% of withdrawers for whom we could identify an income earned more than $60,000 compared with 26% of non-withdrawers. And withdrawers had lower median bank balances ($618 versus $986).</p> <p>For those with credit cards and home loans, withdrawers were about twice as likely to be behind on repayments as non-withdrawers (9.7% versus 5.8% for credit cards, and 8.2% versus 3.4% for home loans).</p> <p>These characteristics suggest that, despite concerns of the scheme being exploited due to the application process <a href="https://www.abc.net.au/news/2020-09-03/-are-people-being-allowed-to-access-their-super-without-scrutiny/12618002">not requiring any documentation</a>, most of those using the scheme genuinely needed the money.</p> <h2>Where did the money go?</h2> <p>Compared to non-withdrawers, those who withdrew increased their spending (on both essential and discretionary items), paid back high-interest debts, boosted their savings, and became less likely to miss debt payments.</p> <p>Withdrawers spent an average of $331 more per month on debit cards in the three months after withdrawal, and $126 per month in the following three months.</p> <p>They spent an extra $117 per month on credit cards during the first three months, which shrank to an extra $13 per month in the following three months.</p> <p>The average withdrawer spent 7% more per month on groceries than the average age and income matched non-withdrawer, 12% more on utilities such as gas and electricity, 16% more on discretionary shopping, and 20% more on “entertainment,” a Commonwealth Bank category that includes gambling.</p> <h2>Less debt, less falling behind</h2> <p>In the three months that followed withdrawing, withdrawers also averaged $437 less credit card debt and $431 less personal loan debt than age and income matched non-withdrawers, differences that shrank to $301 and $351 in the following three months.</p> <p>They also became less likely to fall behind on credit card and personal loan payments, a difference that vanished after three months.</p> <p>Our interpretation is that the scheme achieved its intended purpose: it provided many Australians in need with a financial lifeline and helped buoy them during uncertain and turbulent times.</p> <h2>Lessons learned</h2> <p>At the same time, our <a href="https://www.sciencedirect.com/science/article/pii/S0313592622001060?via%3Dihub#bfn3">findings</a> identify areas of concern. The fact that most withdrawals were for the permitted maximum of $10,000 highlights the need to carefully consider the withdrawal limit.</p> <p>While these sums might simply reflect the true amount of money individuals needed to sustain themselves, it might be that many withdrawers were unsure of how much to <a href="https://cepar.edu.au/sites/default/files/Determinants%20of%20Early%20Access%20to%20Retirement%20Savings_Lessons%20from%20the%20COVID19%20Pandemic_BatemanDobrescuLiuNewellThorp_July21.pdf">withdraw</a> – not knowing how long the pandemic would continue.</p> <p>Another consideration is how to best support withdrawers after they have taken out the money. More than half were under the age of 35, and might find themselves with a good deal less super than they would have in retirement.</p> <p>The government has already introduced <a href="https://www.ato.gov.au/super/apra-regulated-funds/in-detail/apra-resources/re-contribution-of-covid-19-early-release-super-amounts/">tax concessions</a> for withdrawers who contribute funds back into their retirement savings accounts. Super funds might also be able to help, by sending targeted messages to those who have withdrawn.<!-- Below is The Conversation's page counter tag.

Qantas found guilty of firing health worker during pandemic

<p>Qantas has been found guilty of firing a health and safety officer during the early days of the pandemic, a NSW district court judge has found.</p> <p>The airline dismissed Theo Seremetidis in early 2020 after he expressed concerns about safety protocol for flights arriving from China in the first months of the Covid-19 pandemic. </p> <p>According to SafeWork NSW, Qantas breached part 6 of the Work Health and Safety Act and discriminated against Mr Seremetidis when he was stood down. </p> <p>On Thursday, the court heard elements of the matter brought by SafeWork NSW were established beyond reasonable doubt and Qantas Ground Services is “guilty of the offence charged”.</p> <p>They specifically related to standing down Mr Seremetidis “to his detriment” and the main reason for his dismissal was a prohibited reason, because he had exercised a power as a health and safety representative by directing workers to cease unsafe work.</p> <p>The prosecution was brought about after Mr Seremetidis launched a complaint about his former workplace with the Transport Workers Union (TWU), who took the complaint to SafeWork NSW. </p> <p>Judge David Russell said he accepted SafeWork NSW’s submissions that Qantas Ground Services “actively sidelined” Mr Seremetidis and ignored his concerns. </p> <div>“Firstly … by cutting him off from other staff who were seeking his help,” he said.</p> <p>“And secondly, by standing him down and requiring him to leave the airport forthwith.</p> <p>“I formed the view that he attempted to carry out his duties as a health and safety representative conscientiously and carefully,” he said. </p> <p>TWU President and NSW/Qld Secretary Richard Olsen welcomed the verdict on SafeWork NSW’s primary charge. </p> <p>“This is a fantastic result. Theo is a workplace hero and today he has been vindicated. When the TWU urged SafeWork NSW to prosecute this case, Theo courageously took on one of Australia’s biggest corporate bullies and won,” he said.</p> <p><em>Image credits: TWU</em></p> </div>

We probably all remember the high-profile COVID outbreaks that occurred on cruise ships in 2020.</p> <p>So what is it about cruise ships that can make them such hotspots for infection?</p> <h2>First, what causes these outbreaks?</h2> <p>Respiratory infectious outbreaks on cruise ships may be caused by <a href="https://wwwnc.cdc.gov/travel/yellowbook/2024/air-land-sea/cruise-ship-travel">a range of pathogens</a> including SARS-CoV-2 (the virus that causes COVID) and influenza viruses. These can be spread by <a href="https://www.pnas.org/doi/10.1073/pnas.2015482118">respiratory droplets and aerosols</a> released when people breathe, talk, laugh, cough and sneeze.</p> <p>Historically, <a href="https://jmvh.org/article/the-navy-and-the-1918-19-influenza-pandemic/">troop transport ships</a> also helped to spread the lethal 1918 flu virus between continents.</p> <p>Gastro outbreaks on cruise ships are similarly well documented. More than 90% of cruise ship gastro outbreaks are caused by <a href="https://wwwnc.cdc.gov/travel/yellowbook/2024/air-land-sea/cruise-ship-travel#infectious">norovirus</a>, which is spread from person to person, and through contaminated objects or contaminated food or water.</p> <p>Gastro can also be caused by other pathogens such as <a href="https://wwwnc.cdc.gov/travel/yellowbook/2024/air-land-sea/cruise-ship-travel">bacteria in contaminated food or water</a>.</p> <h2>What is the risk?</h2> <p>In 2020, around 19% of <a href="https://www.bmj.com/content/369/bmj.m1632">Diamond Princess</a> passengers and crew docked in Japan tested positive to COVID. Ultimately, nearly one in four <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8739343/">Ruby Princess</a> passengers and crew docked in Sydney tested positive.</p> <p>However, COVID generally presents a lesser risk nowadays, with most people having some level of immunity from vaccination or previous infection. The outbreak on the Grand Princess appears to have been much smaller in scale.</p> <p>A <a href="https://www.sciencedirect.com/science/article/abs/pii/S1477893916300680">three-year study</a> before COVID of influenza-like illness (which includes fever), acute respiratory illness (which <a href="https://www.cdc.gov/flu/about/glossary.htm">doesn’t require fever</a> to be present) and gastro on cruise ships found these were diagnosed in 32.7%, 15.9% and 17% of ill passengers, and 10.9%, 80% and 0.2% of ill crew, respectively.</p> <p>An <a href="https://www.cdc.gov/mmwr/volumes/70/ss/ss7006a1.htm">analysis</a> of data from 252 cruise ships entering American ports showed the overall incidence of acute gastro halved between 2006 and 2019. Passenger cases decreased from 32.5 per 100,000 travel days to 16.9, and crew cases from 13.5 per 100,000 travel days to 5.2. This decline may be due to a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6382806/">combination</a> of improved hygiene and sanitation standards.</p> <p>The risk of getting sick with gastro was significantly higher on <a href="https://www.cdc.gov/mmwr/volumes/70/ss/ss7006a1.htm">bigger ships and longer voyages</a>. This is because the longer you are in close contact with others, the greater the chance of exposure to an infectious dose of viruses or bacteria.</p> <h2>Why are cruise ships infection hotspots?</h2> <p>On cruise ships, people tend to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8739343/">crowd together</a> in confined spaces for extended periods. These include dining halls, and during social activities in casinos, bars and theatres.</p> <p>The risk goes up when the environment is noisy, as more droplets and aerosols are shed when people are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6382806/">laughing, shouting or talking loudly</a>.</p> <p>Passengers may come from <a href="https://www.sciencedirect.com/science/article/abs/pii/S1477893916300680?via%3Dihub">multiple countries</a>, potentially bringing variants from different parts of the world. Influenza, which is usually seasonal (late autumn to early spring) onshore, can occur at any time <a href="https://academic.oup.com/cid/article/31/2/433/295546">on a cruise ship</a> if it has international passengers or is calling at international ports.</p> <p>Human behaviour also contributes to the risk. Some passengers <a href="https://academic.oup.com/jtm/article/15/3/172/1821220">surveyed</a> following cruise ship gastro outbreaks indicated they were ill when they boarded the ship, or they became ill but didn’t disclose this because they didn’t want to pay for a doctor or be made to isolate, or they thought it wasn’t serious.</p> <p>Those who became ill were more likely than those who did not to think that hand hygiene and isolation were not effective in preventing infection transmission, and were less likely to wash their hands after using the toilet. Given <a href="https://www.health.nsw.gov.au/Infectious/factsheets/Pages/norovirus.aspx">faecal contamination</a> is a major source of norovirus transmission, this is concerning.</p> <p>While there are usually a la carte dining options on board, many people will choose a buffet option. From personal experience, food tongs are handled by multiple people, some of whom may not have cleaned their hands.</p> <h2>What can help?</h2> <p>The <a href="https://www.health.gov.au/news/ahppc-statement-advice-to-support-safe-cruising">Department of Health and Aged Care</a> recommends cruise companies encourage crew and passengers to be up-to-date with flu and COVID vaccinations, and encourage anyone who becomes ill to stay in their cabin, or at least avoid crowded spaces and wear a mask in public.</p> <p>They also recommend cruise ships have a plan to identify and contain any outbreaks, including testing and treatment capacity, and communicate to passengers and crew how they can reduce their transmission risk.</p> <p>All passengers and crew should report any signs of infectious illness, and practice good hand hygiene and <a href="https://www.cdc.gov/oralhealth/infectioncontrol/faqs/respiratory-hygiene.html">respiratory etiquette</a>, such as covering their mouth if coughing or sneezing, disposing of used tissues, and washing or sanitising hands after touching their mouth or nose.</p> <p>South Australia’s chief health officer has <a href="https://www.abc.net.au/news/2023-11-13/grand-princess-ship-covid-gastro-docks-in-adelaide/103096836">commended</a> the Grand Princess crew for their infection protection and control practices, and for getting the outbreak under control.<!-- Below is The Conversation's page counter tag.
