Eight key questions about lab-grown meat

<div class="copy"> <p>It’s been around for a decade now — but <a href="https://cosmosmagazine.com/podcast/lab-grown-meat/" target="_blank" rel="noreferrer noopener">cultured meat</a> still faces some huge hurdles.</p> <p>On 5 August, it will be ten years since the world was introduced to <a href="https://www.bbc.com/news/science-environment-23576143" target="_blank" rel="noreferrer noopener">the first lab-grown burger</a>.</p> <p>A decade after its arrival, biotechnologist Professor Paul Wood answers eight key questions about cultured meat.</p> <h2>What is lab-grown meat?</h2> <p>Cultured meat, also colloquially referred to as lab-grown meat, is <a href="https://academic.oup.com/af/article/13/2/68/7123477" target="_blank" rel="noreferrer noopener">the concept</a> of taking a biopsy from a living animal, selecting an individual cell type and growing these cells in large scale <a href="https://journals.physiology.org/doi/abs/10.1152/ajpcell.00408.2022" target="_blank" rel="noreferrer noopener">bioreactors</a>.</p> <p>Technically, it’s a viable alternative to growing an animal to maturity before harvesting meat from its carcass.</p> <p>Multiple cell types can be used from animals, such as muscle, fat or <a href="https://www.genome.gov/genetics-glossary/Fibroblast" target="_blank" rel="noreferrer noopener">fibroblasts</a>.</p> <p>The initial stage of cell selection requires the <a href="https://www.sciencedirect.com/science/article/pii/B9780123745538002537" target="_blank" rel="noreferrer noopener">creation of a cell line</a> which will grow continuously in a selective culture medium.</p> <h2>How long has it been around?</h2> <p>The technology for the culture of cells in laboratories has been used for many decades to produce drugs like <a href="https://www.cancer.gov/about-cancer/treatment/types/immunotherapy/monoclonal-antibodies" target="_blank" rel="noreferrer noopener">monoclonal antibodies</a> or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7161866/" target="_blank" rel="noreferrer noopener">viral vaccines</a>.</p> <p>The difference with cultured meat is the cells themselves are used to produce edible products rather than used as production systems for monoclonals or viral antigens.</p> <p>Cultured meat was first introduced back in 2013 with <a href="https://www.bbc.com/news/science-environment-23576143" target="_blank" rel="noreferrer noopener">the unveiling of the world’s first lab-grown burger</a>, which cost a whopping USD$330,000 to produce.</p> <p>The first commercial cultured meat product was <a href="https://www.bbc.com/news/business-55155741" target="_blank" rel="noreferrer noopener">a chicken nugget licensed in Singapore</a> in 2020.</p> <p><a href="https://www.scientificamerican.com/article/lab-grown-meat-approved-for-sale-what-you-need-to-know/" target="_blank" rel="noreferrer noopener">In June 2023</a>, the US Department of Agriculture granted two companies — Upside Foods and Good Meat — licences to sell chicken-based products.</p> <p>Significant excitement ensued in the food industry with <a href="https://www.liebertpub.com/doi/abs/10.1089/ind.2021.29240.ctu?journalCode=ind" target="_blank" rel="noreferrer noopener">predictions</a> that cultured meat will transform the meat industry by 2030.</p> <h2>Is lab-grown meat commercially viable?</h2> <p>Currently <a href="https://gfi.org/resource/cultivated-meat-eggs-and-dairy-state-of-the-industry-report/" target="_blank" rel="noreferrer noopener">around USD$3 billion</a> has been invested in over 150 companies working on beef, chicken, pork, lamb and exotic cell-based products. <a

<p>Upside Foods has launched its <a href="https://edition.cnn.com/2023/07/01/business/lab-grown-chicken-san-francisco/index.html" target="_blank" rel="noreferrer noopener">new cell-based chicken product in a Michelin star restaurant</a>, but it is only available one night a month and the price has not been disclosed.</p> <p>Commercial success will require significant scaling in production, <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/bit.27848" target="_blank" rel="noreferrer noopener">cost reductions</a> and consumer acceptance, or these products will be confined to niche markets for wealthy consumers.</p> <p>Cultured meat is unlikely to be the solution for the <a href="https://www.mdpi.com/2304-8158/6/7/53" target="_blank" rel="noreferrer noopener">increasing protein needs of developing nations</a>.</p> <p>The <a href="https://academic.oup.com/af/article/13/2/68/7123477" target="_blank" rel="noreferrer noopener">technical challenges</a> involve scaling up cell growth in over 10,000 litre fermentation vessels, while significantly reducing the cost of cell-culture media, the capital cost of equipment and the operating cost of high-quality sterile biocontainment facilities.</p> <p>It has been estimated that the cost of production of cultured meat <a href="https://cedelft.eu/publications/tea-of-cultivated-meat/" target="_blank" rel="noreferrer noopener">must be reduced by over 1,000-fold</a> to match that of conventional meat production.</p> <p>Proponents of cultured meat like to quote the concept of <a href="https://ourworldindata.org/moores-law" target="_blank" rel="noreferrer noopener">Moore’s law</a> that predicts that the cost of all new technology will be significantly reduced with time. However this law has never been applied to a biological system that has innate growth limits.</p> <h2>Is it good for you — and does it taste okay?</h2> <p>Currently <a href="https://www.nature.com/articles/s41467-020-20061-y" target="_blank" rel="noreferrer noopener">all cultured meats are hybrid or blended products</a>, in which the harvested cell paste — the meat component — is combined with plant-based materials, plus vitamins and minerals to produce burgers, meatballs, sausages and dumplings.</p> <p>Yes, you have to add the vitamins in, and no, you can’t make a steak with it yet.</p> <p>From a commercial perspective this is important, as cultured meat products will compete in the commodity meat market.</p> <p>Cultured meat does not produce a three-dimensional steak with multiple cell types and complex taste and texture.</p> <p>However, <a href="https://www.forbes.com/sites/lanabandoim/2021/02/12/worlds-first-3d-bioprinted-and-cultivated-ribeye-steak-is-revealed/?sh=4b6baf0a4781" target="_blank" rel="noreferrer noopener">there are companies</a> aiming to develop whole cuts of meat using 3D printing and bioengineering technology.</p> <h2>What is the motivation to produce cell-cultured meat?</h2> <p>The drivers for cultured meat are that <a href="https://www.abc.net.au/news/rural/2018-05-06/vegan-alternative-plant-based-meat-grown-in-lab/9726436" target="_blank" rel="noreferrer noopener">animals are not slaughtered</a>, there can be less land and water usage and less greenhouse gases are produced than conventional meat production, particularly from ruminants like cattle and sheep.</p> <p>A lower manufacturing footprint is a terrific plus. And not killing animals is something a lot of people advocate for, but until cultured meat has been scaled significantly, it won’t be known if it’s really better for the planet or for humans.</p> <p>The <a href="https://www.foodnavigator-usa.com/Article/2022/04/21/cultivated-meat-upside-foods-closes-400m-series-c-round-to-support-commercial-scale-plant-with-production-capacity-of-tens-of-millions-of-pounds" target="_blank" rel="noreferrer noopener">largest facility built so far</a> is a pilot plant in the USA that aims to produce around 1,000 pounds (approximately 450 kilograms) of product per week, which is equivalent to the dressed weight of three carcasses — what a single suburban butcher processes in one day.</p> <h2>Will it be expensive to buy?</h2> <p>The taste and texture of food is critical to consumers — but so is value for money. So, it’s not surprising <a href="https://www.visualcapitalist.com/cp/mapped-meat-consumption-by-country-and-type/" target="_blank" rel="noreferrer noopener">chicken is the dominant choice of meat</a> currently.</p> <p>With high-end lab-grown meat products, both taste and texture can most likely be matched, and with supplementation with vitamins like B12 it should be possible to make cultured meat nutritionally equivalent to its traditional counterpart too.</p> <p>However, cost will be a major challenge and sales data indicated that <a href="https://www.freshplaza.com/oceania/article/9535792/consumers-are-not-willing-to-pay-more-for-sustainability/" target="_blank" rel="noreferrer noopener">consumers will not pay any significant premium for slaughter-free or more sustainable products</a>.</p> <h2>Who wants to eat meat grown in a factory?</h2> <p>There are also questions around who the consumers will be for cultured meat.</p> <p>Vegans avoid animal products, vegetarians often reject the taste of meat and this new group of <a href="https://www.sciencedirect.com/science/article/pii/S0924224421003952" target="_blank" rel="noreferrer noopener">flexitarians</a>, while interested in trying new products, are seldom converted to <a href="https://www.foodnavigator.com/Article/2021/11/16/What-do-flexitarian-consumers-want-Plant-based-innovation-opportunities-revealed" target="_blank" rel="noreferrer noopener">regular customers</a>.</p> <p>In the US at least, this is one of the reasons that the many plant-based meat products have only captured <a href="https://gfi.org/marketresearch/#plant-based-meat" target="_blank" rel="noreferrer noopener">1.3 percent of the meat market</a>.</p> <p>It is also likely that plant-based products will be a <a href="https://www.mckinsey.com/industries/agriculture/our-insights/alternative-proteins-the-race-for-market-share-is-on" target="_blank" rel="noreferrer noopener">major competitor</a> to these new cultured meat products.</p> <h2>Who will be next to approve cell-cultured meat?</h2> <p>While the first cultured meat products have been licensed in Singapore and the US, it is expected more will follow from other regions.</p> <p>Even though <a href="https://www.fao.org/food-safety/scientific-advice/crosscutting-and-emerging-issues/cell-based-food/en/" target="_blank" rel="noreferrer noopener">a recent FAO report</a> identified over 50 potential health risks with cultured meat, it concluded that the overall risk was not greater than that seen with conventional meat products.</p> <p>There could be delays in Europe due to the conservative regulatory approach taken in the EU. In Australia, products are <a href="https://www.abc.net.au/news/rural/2023-06-27/cultured-lab-meat-to-sell-in-australia-to-rival-plant-based-meat/102527330" target="_blank" rel="noreferrer noopener">expected to be approved in 2024</a>.</p> <p>For now though? Well, the message to Aussie meat producers is … don’t sell the farm.</p> <p><em>Image credits: Getty Images</em></p> </div> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/health/nutrition/explainer-lab-grown-meat/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="null">Cosmos</a>. </em></p> </div>

Astonishing report identifies Covid’s alleged “patient zero”

<p>A bombshell report has claimed the infamous Covid-19 "patient zero” was a Wuhan scientist carrying out experiments on souped-up coronaviruses.</p> <p>The scientist in question, Ben Hu, was conducting risky tests at the Wuhan Institute of Virology with two colleagues, Ping You and Yan Zhu, the report states.</p> <p>It is understood that all three suffered Covid-like symptoms and required hospital care weeks before China broke the news of the virus outbreak to the rest of the world.</p> <p><em>The Sun</em> reported that the name of “patient zero" has never been disclosed until now.</p> <p>Many US government officials have now identified the three scientists in a shocking report by journalists Michael Shellenberger and Matt Taibbi.</p> <p>Writing in the Substack newsletter <em>Public</em>, the pair alleged the scientists were experimenting with coronaviruses when they fell ill in 2019.</p> <p>Several experts and intelligence officials have long suspected scientists at the lab accidentally spread the virus during so-called “gain of function” experiments on bat coronaviruses.</p> <p>The naming of “patient zero” could prove to be the smoking gun, only adding to mounting circumstantial evidence of a lab leak.</p> <p>It is unclear who in the US government had the intelligence about the sick lab workers, how long they had it, and why it was not shared with the public.</p> <p><em>The Australian</em> journalist and <em>Sky News</em> host Sharri Markson spoke to <em>The Sun</em> about the lab leak theory in 2021 and dubbed it an “explosive development”.</p> <p>Jamie Metzl, a former member of the World Health Organisation advisory committee on human genome editing, described it as a possible “game changer”.</p> <p>“It’s a game changer if it can be proven that Hu got sick with Covid before anyone else,” he said.</p> <p>“That would be the ‘smoking gun’. Hu was the lead hands-on researcher in (virologist Shi Zhengli’s) lab.”</p> <p>DRASTIC, an international team of scientists and sleuths attempting to piece together Covid-19’s origins, researched the three scientists in 2021.</p> <p>The Wuhan Institute of Virology’s website lists Hu’s biography showing he was working as an assistant researcher.</p> <p>He was said to be the “star pupil” of virologist Shi Zhengli — the virologist at the lab who became known as “batwoman” for her research on bat coronaviruses.</p> <p>Markson, the author of <em>What Really Happened in Wuhan</em>, said that Hu was running a state-funded project in 2019 to test if new coronaviruses could infect humans.</p> <p>The study involved souping up the viruses and experimenting with them on humanised mice.</p> <p>However, the results were never published and the study’s existence was erased from the internet as Covid-19 was spreading around the globe, which raised suspicion of a possible lab leak.</p> <p>A source told <em>The Sun</em> that footage from 2017 that was aired by Chinese state-run TV showed Hu working in the lab without protective gear.</p> <p>The same video shows scientists from the Wuhan lab searching for bat viruses with inadequate protective gear.</p> <p>Alina Chan, a molecular biologist at MIT and Harvard, told <em>Public</em>, “Ben Hu is essentially the next Shi Zhengli.</p> <p>“He was her star pupil. He had been making chimeric SARS-like viruses and testing these in humanised mice.</p> <p>“If I had to guess who would be doing this risky virus research and most at risk of getting accidentally infected, it would be him.”</p> <p>She noted, “If this info had been made public in May of 2020, I doubt that many in the scientific community and the media would have spent the last three years raving about a raccoon dog or pangolin in a wet market.”</p> <p>US scientist Dr Steven Quay, “He was always my first choice for one of the infected Wuhan Institute of Virology workers but it seemed too simple.”</p> <p>A bill signed by US President Joe Biden in 2023 called for the release of the names of the sick scientists, their symptoms, and whether they had been involved with or exposed to coronavirus research.</p> <p>The US is currently preparing to release previously classified material, which could include the names of the three Wuhan scientists.</p> <p>Earlier in 2023, FBI director Christopher Wray said, “the FBI has for quite some time now assessed that the origins of the pandemic are most likely a potential lab incident in Wuhan”.</p> <p>China has long been accused of attempting to cover up or distort its involvement with Covid-19, but they continue to deny claims.</p> <p>In March 2023, China’s former government scientist confessed the Wuhan lab leak theory shouldn’t be ruled out, sparking uproar in Beijing.</p> <p>Professor George Gao, the former chief of China’s Centre for Disease Control, played a key role in the efforts to trace the origins of Covid-19, insisting scientists should “suspect anything”.</p> <p>Speaking to the BBC Radio 4 podcast <em>Fever: The Hunt for Covid’s Origin</em>, Professor Gao said, “You can always suspect anything. That’s science.</p> <p>“Don’t rule out anything.”</p> <p>Professor Gao retired from the CDC in 2022 after playing a key role in the pandemic response and efforts to find the mysterious origin of the virus.</p> <p>He would have had access to highly classified government information on the outbreak of Covid-19.</p> <p>According to Professor Gao, a formal investigation into the Wuhan Institute of Virology was carried out by a government department.</p> <p>The government scientist claimed the “lab was double-checked by the experts in the field”.</p> <p>Investigators believe scientists were working with the Chinese military to develop a mutant virus and pursue bioweapons just as the pandemic began.</p> <p>The findings followed a team of US investigators who combed through top-secret intercepted communications and research.</p> <p>In 2016, researchers discovered a new fatal type of coronavirus in a mineshaft in Mojiang, Yunnan province.</p> <p>However, they kept it under wraps, with the sample then transported to the Wuhan lab and dubbed as classified work.</p> <p>The virus is the only known immediate relative of Covid-19 known to exist prior to the pandemic.</p> <p>Speaking to<em> The Times</em>, one US investigator said, “The trail of papers starts to go dark.</p> <p>“That’s exactly when the classified program kicked off.</p> <p>“My view is that the reason it was covered up was due to military secrecy related to the army’s pursuit of dual-use capabilities in virological biological weapons and vaccines.”</p> <p>The findings came after a scientist who worked closely with the Wuhan lab claimed the virus was genetically engineered and leaked from the facility.</p> <p><em>Image credit: Getty</em></p>

Covid’s origin found

<p dir="ltr">Amid accusations of it being made in a lab or purposefully made more infectious and fracturing faith in science, scientists say they have finally determined the origin of COVID-19.</p> <p dir="ltr">A team of scientists who have been investigating the virus’ origin have published their findings in two separate articles in <em>Science </em>(available to read <a href="https://www.science.org/doi/10.1126/science.abp8715" target="_blank" rel="noopener">here</a> and <a href="https://www.science.org/doi/10.1126/science.abp8337" target="_blank" rel="noopener">here</a>) and said they are at the end of their search.</p> <p dir="ltr">COVID-19 almost-certainly jumped from animals to humans in Wuhan’s Huanan Seafood Wholesale Market, with the researchers even pinpointing the most likely section of the market where it occurred.</p> <p dir="ltr">“The siren has definitely sounded on the lab leak theory,” Professor Edward Holmes, a world-leading expert on virus evolution and co-author of both papers, told the <em>Sydney Morning Herald</em>.</p> <p dir="ltr">“In terms of what we can reasonably do, with the available science and the science we’ll get in the foreseeable future, I think we’re at the end of the road frankly. There’s not a lot more to mine.”</p> <p dir="ltr">Professor Dwyer, the director of public health pathology in NSW and a member of the World Health Organisation (WHO) team who travelled to Wuhan to investigate Covid’s origins, agrees with the findings.</p> <p dir="ltr">“That’s what we thought originally back when we did the first report,” he said.</p> <p><span id="docs-internal-guid-de65d200-7fff-e4d3-3c8b-fb40bc3f2502"></span></p> <p dir="ltr">“This is yet another brick added to the wall of information around zoonotic infection.”</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Analysis of spatial distributions of early <a href="https://twitter.com/hashtag/COVID19?src=hash&amp;ref_src=twsrc%5Etfw">#COVID19</a> cases and environmental samples from the Huanan market point to the market as the epicenter of <a href="https://twitter.com/hashtag/SARSCoV2?src=hash&amp;ref_src=twsrc%5Etfw">#SARSCoV2</a> emergence, from activities associated with wildlife trade. <a href="https://t.co/tykjmEOGxW">https://t.co/tykjmEOGxW</a> <a href="https://twitter.com/MichaelWorobey?ref_src=twsrc%5Etfw">@MichaelWorobey</a> <a href="https://twitter.com/K_G_Andersen?ref_src=twsrc%5Etfw">@K_G_Andersen</a> <a href="https://t.co/THYDkLualC">pic.twitter.com/THYDkLualC</a></p> <p>— Science Magazine (@ScienceMagazine) <a href="https://twitter.com/ScienceMagazine/status/1551931253179514880?ref_src=twsrc%5Etfw">July 26, 2022</a></p></blockquote> <p dir="ltr">Using Chinese and WHO data, as well as public online maps, photos, business registries, and official reports, the scientists reconstructed a map of the market, including human cases and Covid-postive environmental samples from late 2019.</p> <p dir="ltr">The market wildlife section was found to have COVID-19 all over it, with eight of the earliest human cases working nearby.</p> <p dir="ltr">A stall where COVID-19 was found on a metal cage, a machine used to remove hair and feathers from animals, two carts used for moving animal cages, and a nearby water drain, was also visited by Professor Holmes on a trip to Wuhan in 2014 - where he snapped a photo of caged racoon dogs stacked on top of caged birds.</p> <p dir="ltr">“We can’t prove it is this exact stall but the data is very suggestive,” he said.</p> <p dir="ltr">Racoon dogs, along with badgers, hares, rats and foxes are among several species of animals that Covid moves easily among, all of which were being sold in the market in 2019.</p> <p dir="ltr"><span id="docs-internal-guid-fad47587-7fff-0e06-efe8-1cddecca3178"></span></p> <p dir="ltr">The racoon dogs supplied to the market came from farms in western Hubei, the <em>Science </em>papers note, which is an area known for extensive networks of caves filled with Rhinolophus bats that carry coronaviruses similar to the one that causes COVID-19.</p> <p dir="ltr"><img src="https://oversixtydev.blob.core.windows.net/media/2022/08/wuhan-racoon-dogs.jpg" alt="" width="601" height="533" /></p> <p dir="ltr"><em>Professor Edward Holmes photographed racoon dogs being sold in the Huanan Wildlife Market in 2014. Image: Edward Holmes</em></p> <p dir="ltr">“Raccoon dogs are a suspect,” Professor Holmes added.</p> <p dir="ltr">“I think, strongly, there are a whole bunch of animals out there who have viruses like this that we have not sampled yet.”</p> <p dir="ltr">In their second paper, the team even determined the two viral lineages that were detected a week apart in December 2019, and which one was the most likely one to have been transmitted from animals to humans.</p> <p dir="ltr">Using computers to simulate the most likely sequence of events that would produce the two strains, which differ by two small changes in their genetic codes, they found it exceedingly unlikely that the virus would jump into humans and then split into two strains.</p> <p dir="ltr">Instead, they found that it would be far more likely that multiple strains of Covid had already been circulating in animals, with two strains separately jumping to humans.</p> <p dir="ltr">As for the theory that Covid originated in a lab, you would expect it to be introduced into humans just once - rather than as two distinct lineages - with samples taken from the Huanan market also containing both strains.</p> <p dir="ltr">“That, I think, is pretty good evidence,” Professor Dwyer said.</p> <p dir="ltr">Though supporters of the lab leak theory argue that the market is a perfect super-spreader site, introduced by scientists from the Wuhan Institute of Virology, the scientists found that it isn’t the perfect spreader site that people may think it is.</p> <p dir="ltr">The scientists found that 155 cases in December 2019 were strongly clustered in the suburbs around the market, but that it is a small and rather obscure shopping spot and was among the least-visited of 430 identified possible super-spreader sites in Wuhan.</p> <p dir="ltr">“It’s like going to Coles in Bendigo on a wet Wednesday afternoon. It’s not a thriving mass of humanity,” Professor Holmes said.</p> <p dir="ltr">No-one has proved COVID-19 - or even a twin strain - has been at the Wuhan Institute of Virology either, with no epidemiological evidence showing the virus spreading near the institute.</p> <p dir="ltr">“There’s no emails. There’s no evidence in any of the science. There’s absolutely nothing,” Professor Holmes said.</p> <p dir="ltr">On top of that, Covid wasn’t detected in any of the tens of thousands of blood donations in Wuhan between September and December 2019, nor in thousands of samples taken from patients hospitalised with flu-like symptoms between October and December.</p> <p dir="ltr">“What are the odds that two lineages escape from the lab and both make their way into the market and both cause superspreader events?” Professor Holmes said.</p> <p dir="ltr"><span id="docs-internal-guid-d9a32911-7fff-345d-3948-858a5f899ba8"></span></p> <p dir="ltr">“It’s ridiculous.

Chinese defector has new theory on COVID origins

<p>A Chinese defector has suggested the COVID-19 pandemic began after the virus was potentially leaked amongst participants of the military games in Wuhan in October 2019, months before the deadly outbreak was confirmed by China.</p> <p>Defector and democracy campaigner Wei Jingsheng was speaking with Sky News journalist Sharri Markson for her new book <em>What Really Happened in Wuhan</em>.</p> <p>He said thousands of athletes from around the world came to Wuhan for the Military World Games in October and this was likely the first superspreader event.</p> <p>Jingsheng said: “I thought that the Chinese government would take this opportunity to spread the virus during the Military Games, as many foreigners would show up there,” he said.</p> <p>He claims he was aware of Chinese authorities experimenting with "strange biological weapons", a tip off from a government source, and tried to warn the US but was unsuccessful.</p> <p><strong>Many athletes from different countries reported sickness</strong></p> <p><img style="width: 0px;

Delta variant more infectious than Wuhan strain, study finds

<p><span style="font-weight: 400;">A new study from the UK has found that the Delta strain of COVID-19 is eight times less sensitive to vaccine antibodies than the original Wuhan strain.</span></p> <p><span style="font-weight: 400;">The study also found that changes to the spike protein in the Delta variant improved its ability to replicate and enter cells, in comparison to the Kappa variant.</span></p> <p><span style="font-weight: 400;">The authors say this might explain how the Delta strain has become the most dominant variation of the disease.</span></p> <p><span style="font-weight: 400;">The study, published in the journal </span><em><a rel="noopener" href="https://www.nature.com/articles/s41586-021-03944-y" target="_blank"><span style="font-weight: 400;">Nature</span></a></em><span style="font-weight: 400;">, compared the mutated Delta variant against the mutated Wuhan-1 variant which was used to develop the vaccines.</span></p> <p><span style="font-weight: 400;">The team, led by Ravindra Gupta, a professor of clinical microbiology at the Cambridge Institute of Therapeutic Immunology and Infectious Disease, also analysed infections of 130 healthcare workers across three hospitals in Delhi, India, over six weeks.</span></p> <p><span style="font-weight: 400;">Though each of the workers studied had received both doses of the AstraZeneca vaccine, the researchers found that the vaccine was less effective against the Delta variant than other variants.</span></p> <p><span style="font-weight: 400;">“By combining lab-based experiments and epidemiology of vaccine breakthrough infections, we’ve shown that the Delta variant is better at replicating and spreading than other commonly-observed variants,” Professor Gupta </span><a rel="noopener" href="https://www.cam.ac.uk/research/news/spread-of-delta-sars-cov-2-variant-driven-by-combination-of-immune-escape-and-increased-infectivity" target="_blank"><span style="font-weight: 400;">said</span></a><span style="font-weight: 400;">.</span></p> <p><span style="font-weight: 400;">Joint senior author Dr Patha Rakshit from the National Centre for Disease Control, Delhi, India, said: “The Delta variant has spread so widely to become the dominant variants worldwide because it is faster to spread and better at infecting individuals than most other variants we’ve seen.</span></p> <p><span style="font-weight: 400;">“It is also better at getting around existing immunity - either through previous exposure to the virus or vaccination - though the risk of moderate to severe disease is reduced in such cases.”</span></p> <p><span style="font-weight: 400;">Professor Anurag Agrawal from the CSIR Institute of Genomics and Integrative Biology, Delhi, India and joint senior author said the infection of healthcare workers with the Delta variant could have severe consequences.</span></p> <p><span style="font-weight: 400;">“Although they themselves may only exhibit mild COVID, they risk infecting individuals who have suboptimal immune responses to vaccination due to underlying health conditions - and these patients could then be at risk of severe disease,” Professor Agrawal said.</span></p> <p><span style="font-weight: 400;">With their findings, Gupta and his colleagues say we will need to develop strategies for boosting the effectiveness of vaccines against variants of COVID-19.</span></p> <p><span style="font-weight: 400;">“We urgently need to consider ways of boosting vaccine responses against variants among healthcare workers,” Professor Agrawal added.</span></p> <p><span style="font-weight: 400;">“[This research] also suggests infection control measures will need to continue in the post-vaccine era.”</span></p>

Chance of COVID emerging naturally is “one in a million”

<p><span style="font-weight: 400;">As COVID-19 vaccinations continue to be administered and the number of coronavirus cases remains low in Australia (or New Zealand), scientists are looking to answer one remaining question: where did the virus come from?</span></p> <p><strong>The lab leak theory</strong></p> <p><span style="font-weight: 400;">Dr Steven Quay, the chief executive of biopharmaceutical company Atossa Technologies and former faculty member at Stanford University’s School of Medicine, said the probability of SARS-CoV-2 emerging naturally was “literally one in a million”.</span></p> <p><span style="font-weight: 400;">Presenting at a conference organised by the Hudson Institute in Washington DC alongside astrophysicist Professor Richard Muller, the pair accused Chinese scientists of concealing the origins as a manufactured virus.</span></p> <p><span style="font-weight: 400;">The increased interest in the origin of the virus comes after the US government ordered its intelligence agencies to investigate the origins of COVID-19.</span></p> <p><span style="font-weight: 400;">Dr Quay said the </span><a href="https://www.who.int/publications/i/item/who-convened-global-study-of-origins-of-sars-cov-2-china-part"><span style="font-weight: 400;">report conducted by the World Health Organisation</span></a><span style="font-weight: 400;">, tabled in March, had “censored” the earliest cases of COVID-19 outside of the Wuhan wet market.</span></p> <p><span style="font-weight: 400;">“This is not science, this is obfuscation,” he added.</span></p> <p><span style="font-weight: 400;">Professor Muller said there were concerns scientists who pursued the “lab leak” theory would be “blacklisted and labelled an enemy of China”.</span></p> <p><strong>An alternative theory</strong></p> <p><span style="font-weight: 400;">Others theorise that the Wuhan Institute of Virology had been performing “gain of function” experiments - where a virus is manipulated to make it more infectious.</span></p> <p><span style="font-weight: 400;">This kind of research has been conducted at labs around the world, according to Professor Dwyer.</span></p> <p><span style="font-weight: 400;">“The institute haven’t published anything significant on gain-of-function studies. I’m not an expert in that area, but my understanding is they weren’t doing gain-of-function work that has been obviously traceable.”</span></p> <p><strong>Flaws in the theory</strong></p> <p><span style="font-weight: 400;">Though some have labelled the WHO report as inconclusive, the 17 international experts who produced the report concluded the most likely origin of the pandemic came from the virus jumping between species - possibly from bats to pangolins - and then to humans.</span></p> <p><span style="font-weight: 400;">Professor Dwyer, director of public health pathology in NSW and one of the experts who contributed to the report, said the key flaw in the lab leak theory was there was no evidence the Wuhan Institute of Virology had the virus before the pandemic.</span></p> <p><span style="font-weight: 400;">“The laboratory leak, for that to be the origin … meant they must have had the virus to begin with, and we don’t have evidence of that,” he said.</span></p> <p><span style="font-weight: 400;">“The lab leak sits there, but you need some sort of evidence to take it further.”</span></p> <p><span style="font-weight: 400;">The institute had been working to find and publish papers on new bat coronaviruses, including a virus that is the closest known match to COVID-19 so far, and Professor Dwyer said it was unlikely the institute would have had SARS-CoV-2 and not published anything about it.</span></p> <p><span style="font-weight: 400;">“They are a pretty prominent research institute. They publish a lot of very good papers and have collaborations with people around the world. If they had it, there was no reason to hide it from a scientific or intellectual point of view.”</span></p> <p><span style="font-weight: 400;">Additionally, some have argued that the lack of an identified intermediate host for the coronavirus supports the lab leak theory, with science journalist Nicholas Wade claiming the SARS intermediate was found within four months of that outbreak.</span></p> <p><span style="font-weight: 400;">But, Professor Dwyer said it actually took 15 years to find the animal source of SARS.</span></p> <p><span style="font-weight: 400;">“These things can take time,” he said.</span></p> <p><span style="font-weight: 400;">“We felt transmission from bat to some sort of intermediate animal to humans was the most likely because it has occurred before - and not just once before, but several times.</span></p> <p><span style="font-weight: 400;">“Based on history, based on things like what markets are like in Wuhan and other neighbouring countries … that seems to be the most likely scenario for it to develop.”</span></p>

Australia's only scientist on Wuhan team delivers COVID-19 origin update

<p>Australian scientist Professor Dominic Dwyer believes that COVID-19 started in China and had been circulating around the community much earlier than December 2019.</p> <p>Dwyer is involved in the inquiry into the origins of COVID-19 and his views have been challenged by the Chinese scientists in the World Health Organisation joint investigation who believe the disease might've been brought into China on frozen food packets.</p> <p>Dwyer, a microbiologist and infectious disease expert with NSW Health Pathology said that the evidence is "very limited" for an origin outside of China.</p> <p>He was the only Australian in a 14-strong team working for the World Health Organisation.</p> <p>WHO experts said last night that COVID-19 most likely appeared in humans after jumping from an animal, dismissing claims that the virus leaked from a Chinese lab.</p> <p>"I think it started in China, I think the evidence for it starting elsewhere in the world is actually very limited," Professor Dwyer told<span> </span><a rel="noopener" href="https://www.9news.com.au/" target="_blank">9News</a><span> </span>from hotel quarantine in Sydney.</p> <p>"There is some evidence but it's not really very good.</p> <p>"I think it's most likely that it came from a bat.

Wuhan doctors admit they were told to lie about severity of COVID-19

<p><span>Chinese doctors in Wuhan have been secretly filmed admitting to knowing how serious coronavirus was at the start of the outbreak, but were ordered to lie by authorities.</span><br /><br /><span>There is growing evidence the Chinese Communist Party misled the global community in the early stages of the pandemic, a new documentary by UK broadcaster ITV called Outbreak: <em>The Virus That Shook The World,</em> has claimed.</span><br /><br /><span>China informed the World Health Organisation (WHO) of the first 27 cases of COVID-19 on December 31, 2019.</span><br /><br /><span>However they did not report any deaths until mid-January.</span><br /><br /><span>But senior doctors in Wuhan were secretly filmed by a citizen journalist, and said they knew about the deaths as early as December.</span><br /><br /><span>“We all felt there shouldn’t have been any doubt about human-to-human transmission,” one doctor said in the footage.</span></p> <p><img style="width: 500px; height: 281.25px;" src="https://oversixtydev.blob.core.windows.net/media/7839576/wuhan-covid-1.jpg" alt="" data-udi="umb://media/839cf6b95524475189c53af0e096ed0a" /><br /><br /><span>“Actually, at the end of December or beginning of January, the relative of someone I know died of this virus. Many of those living with him were also infected including people I know.”</span><br /><br /><span>Another doctor said: “We knew the virus transmitted from human to human, but when we attended a hospital meeting we were told not to speak out. Provincial government leaders told the hospitals not to tell the truth.”</span><br /><br /><span>The doctors claimed that authorities knew the January Lunar New Year celebrations would accelerate the spread of the virus.</span><br /><br /><span>However they allowed the festivities to go ahead anyway in order to “present a harmonious and prosperous society”.</span><br /><br /><span>“They shouldn’t have allowed any gatherings,” one said.</span><br /><br /><span>“The provincial and local governments knew the threat but they continued to allow crowds.”</span><br /><br /><span>WHO infamously tweeted on January 14 about the virus: “Preliminary investigations conducted by the Chinese authorities have found no clear evidence of human-to-human transmission.”</span><br /><br /><span>Taiwanese experts interviewed by the program backed up the Wuhan doctors’ testimony.</span><br /><br /><span>Dr Yin-Ching Chuang from the country’s Infectious Diseases Prevention and Treatment Network said his team struggled to get an answer on whether the virus was spread through hand-to-hand transmission.</span><br /><br /><span>After they were granted permission to travel to China, the truth finally emerged in a meeting.</span><br /><br /><span>“We asked a lot of questions, very unwillingly they finally came out and said limited human-to-human transmission can’t be ruled out,” he said.</span><br /><br /><span>“What was the scale of infection?

China bans WHO access to Wuhan

<p>China has prevented the World Health Organisation investigators from entering Wuhan, the Chinese province largely believed to be the epicentre of the coronavirus.</p> <p>According to reports, Beijing is avoiding the independent WHO probe, which was expected to take four to five weeks in efforts to avoid being held accountable for the coronavirus pandemic.</p> <p>“Today, we learned that Chinese officials have not yet finalised the necessary permissions for the team’s arrival in China,” WHO Director-General Tedros Adhanom Ghebreyesus told reporters yesterday at a press conference in Geneva.</p> <p>“I’m very disappointed with this news, given that two members had already begun their journeys and others were not able to travel at the last minute.</p> <p>“I have been in contact with senior Chinese officials and I have once again made it clear the mission is a priority for WHO and the international team.”</p> <p>The WHO's Dr Michael Ryan said that the officials on the ground have not been given visa clearances, with one being sent back home and another staying in a different country until they have been given access to Wuhan.</p> <p>“We trust and we hope that this is just a logistic and bureaucratic issue (and) will be resolved quickly,” Dr Ryan said.</p> <p>“This is frustrating and as the Director-General has said this is disappointing. We trust in good faith we can solve these issues in coming hours and recommence the deployment of the team as urgently as possible.”</p> <p>The independent probe comes after the Chinese prvince of Hebei has plunged into "wartime mode" after an outbreak of 59 cases in the last three days.</p> <p>Officials have launched mass testing for the 11 million residents, schools have shut and the infections are thought to have been spread through social events such as gatherings and weddings.</p> <p><em>The Global Times</em><span> </span>published a story just days ago saying that Wuhan is hosting "more gatherings" in the New Year and that the "west" should "get used to it".</p> <p>“More big gatherings like the New Year celebrations, sports events and live concerts will be staged in Wuhan, which was the hardest-hit city in China by COVID-19, during 2021, and the world had better get used to it, Wuhan residents said, calling on some Westerners to save their fellow countrymen following Chinese experiences rather than attacking Wuhan’s gatherings with prejudice and hostility,” the article read.</p> <p>“When large crowds of Wuhan residents took to streets and launched balloons to celebrate the arrival of 2021 on New Year’s Eve, in sharp contrast with what Western media called a ghost town like Times Square with roads closed but no live audience, some Westerners with jealous eyes were sarcastic about Wuhan.”</p>

Chinese whistleblower claims she has proof COVID-19 came from Wuhan lab

<p>A Chinese virologist has made claims that COVID-19 was manufactured in a laboratory and did not come from “nature” like the Chinese government is claiming.</p> <p>Doctor Li-Meng Yan, a scientist who conducted some of the earliest research on COVID-19, joined the British talk show <em>Loose Women </em>to share her claims.</p> <p>She says that reports the virus came from a wet market are a “smokescreen”.</p> <p>“It comes from the lab, the lab in Wuhan and the lab is controlled by China’s government,” she said.</p> <p>She says her source are “local doctors”.</p> <p>“The first thing is the market in Wuhan ... is a smokescreen.</p> <p>“This virus is not from nature.”</p> <p>Yan earlier claimed she was told to keep a secret about the possibility of human-to-human transmission of COVID-19 back in December.</p> <p>She went on to say that former supervisors at the Hong Kong School of Public Health silenced her when she tried to sound the alarm.</p> <p>She fled Hong Kong for America in April.</p> <p>Dr Yan’s next plan is to release genomic sequencing that she says will trace the virus back to a lab.</p> <p>“The genome sequence is like a human fingerprint,” she said.</p> <p>“So based on this you can identify these things. I use the evidence … to tell people why this has come from the lab in China, why they are the only ones who made it.”</p> <p>China has repeatedly said that COVID-19 may not have originated in Asia at all.</p> <p>In July, the country pointed its finger at Spain, claiming that wastewater testing there found traces of the virus in March 2019.</p>

COVID-19 epicentre Wuhan records new cluster of cases after relaxing lockdown

<p>The Chinese city of Wuhan has reported six new cases of COVID-19 over the last few days which marks the first officially documented re-emergence of the virus in over a month.</p> <p>Wuhan is the city where the coronavirus first broke out last December and had not recorded a new case since April 3rd. The city had since eased lockdowns and reopened schools.</p> <p>The first new Wuhan case was previously asymptomatic, and the 89-year-old man had not left his residential compound since the Lunar New Year in late January.</p> <p>His wife also tested positive for the virus despite showing no symptoms, the Wuhan municipal health commission said.</p> <p>The residential compound has had 20 confirmed cases and experts say that the new round of infections was mainly due to previous community infections.</p> <p>The new cases highlight the potential for new clusters of infections due to carriers who do not look ill or have a fever.</p> <p>On Sunday, authorities also reported new coronavirus cases in northeast China, with one city in Jilin province being reclassified as high-risk, the top of a three-tier zoning system.</p> <p>The city of Shulan was raised from medium to high after raising it from low to medium the day before after a woman tested positive on May 7th.</p> <p>The new cases spike the overall number of confirmed new cases in mainland China to 14, which is the highest reported number since April 28.</p> <p>In Wuhan, more than 20,000 people will be tested in the area where the cluster of new cases was found.</p> <p>Almost 4,000 people have died across the city according to the official tally.</p> <p>There is speculation that the figure could be higher as China faces questions from other countries about the accuracy of its reporting on COVID-19 cases.</p>

“We’ll hold those responsible accountable”: US claims virus came from Wuhan lab

<p>The US Secretary of State Mike Pompeo has claimed there was “enormous evidence” the new coronavirus originated in a Chinese laboratory, but did not provide any of the alleged evidence.</p> <p>Pompeo, a former director of the Central Intelligence Agency, said on Sunday there was “enormous” and “significant” evidence that the coronavirus outbreak began in a laboratory in Wuhan, China.</p> <p>“I think the whole world can see now, remember, China has a history of infecting the world and running substandard laboratories,” Pompeo told ABC’s <em>This Week</em>.</p> <p>“President Trump is very clear: we’ll hold those responsible accountable.”</p> <p>At first, Pompeo said he believed “the best experts so far seem to think it was man-made”.</p> <p>But he later said he agreed with the “wide scientific consensus” from the US intelligence community that “the COVID-19 virus was not man-made or genetically modified”.</p> <p>Pompeo’s statement indicated an escalation in rhetoric amid the country’s tensions with China.</p> <p>US President Donald Trump made a similar unsupported claim on Thursday, saying that <a href="https://www.theguardian.com/us-news/2020/apr/30/donald-trump-coronavirus-chinese-lab-claim">he had proof the pandemic started in a Chinese laboratory</a>.</p> <p>On the same day, Pompeo said in an interview: “We don’t know if it came from the Wuhan Institute of Virology.

“It’s unfathomable”: Scott Morrison responds to WHO decision

<p>Australian Prime Minister Scott Morrison has torn into the World Health Organisation for the “unfathomable” decision as WHO supports the reopening of China’s wet markets.</p> <p>As experts believe that the new coronavirus originated at a wet market in the Chinese city of Wuhan, closure of the wet markets would be ideal. However, WHO says that it does not support the closure of the markets as “they are a source of livelihood and food security to many people”.</p> <p>Morrison has rejected this idea wholeheartedly as he spoke to<span> </span>Nine’s<em> <a rel="noopener noreferrer" href="https://7news.com.au/lifestyle/health-wellbeing/pm-puzzled-by-unfathomable-animal-markets-c-973992" target="_blank">Today</a>.</em></p> <p>“It’s unfathomable, frankly,” Mr Morrison explained.</p> <p>“We need to protect the world against potential sources of outbreaks of these types of viruses. It’s happened too many times. I’m totally puzzled by this decision. We don’t have them here in Australia. I am just puzzled by that decision.”</p> <p>Health Minister Greg Hunt is also baffled by China’s plans to reopen the markets.</p> <p>"There is a very real likelihood that this disease arose from a wet market in Wuhan – it's clear that these are dangerous vectors," Mr Hunt told the ABC.</p> <p>"So we might disagree on this issue with some of the international authorities, but our job is to protect Australians, and I would imagine that around the world, the vast majority of people would have a similar view."</p> <p>University of Melbourne Chinese Studies lecturer Delia Lin said that there is a “genuine linguistic misunderstanding” of what wet markets actually are.</p> <p>“The term has been politically charged in the west and has been associated with coronavirus cover-ups and wildlife trading,” Dr Lin told<span> </span><em><a rel="noopener noreferrer" href="https://www.sbs.com.au/news/morrison-chides-who-as-wet-markets-reopen-in-china-s-coronavirus-epicentre" target="_blank">SBS News</a>.</em></p> <p>“In China people would think that is absurd. Wet markets in China are more like a farmers' market in Australia.”</p> <p>However, Dr Lin agrees that China has vast improvements to make in terms of animal welfare.</p> <p>“Wildlife trading markets have been banned but China does need to do a lot more to protect animals,” she said.</p> <p>“For example, the annual dog meat festival still goes on and it should be banned.”</p> <p>The World Health Organisation said that although wet markets in China are able to go forward, it is necessary to regulate them.</p> <p>“But it is necessary to regulate them and introduce measures to decrease the risk of transmission of diseases at them,” the WHO told SBS News in a statement.</p> <p>“With adequate facilities, proper regulation and good hygiene practices it is possible to have safe food sold in wet markets.”</p> <p>“It is WHO’s understanding that these laws continue to be enforced through provincial and municipal authorities under central government oversight,” the statement said.</p>

Coronavirus in Wuhan: Residents shout ‘stay strong’ from windows

<p>In Wuhan, China, the epicentre of the coronavirus outbreak, <a href="https://youtu.be/bqXfnN76S-I">residents have been shouting</a> “Wuhan <em>jiāyóu</em>” meaning, “Wuhan, stay strong” out of their windows, from apartment building to apartment building, to <a href="https://www.bbc.com/news/world-asia-china-51276496">send words of encouragement</a> to fellow citizens, doctors and medical staff at the front lines of the battle.</p> <p>When facing a crisis, <a href="https://doi.org/10.1080/03057240.2011.541774">humans historically seek solidarity</a>.

As fears grew, some felt the need to boost morale and create a sense of community solidarity.</p> <p>Soon, social media posts circulated asking residents in Wuhan to go to their windows and shout out “<em>jiāyóu</em>” starting at 8 p.m. local time. The posts were widely shared, leading to the phenomenon that took place.</p> <p><em>Jiāyóu</em> (加油) directly translates to “<a href="https://www.bbc.com/news/av/world-asia-45897668/add-oil-the-new-expression-coming-your-way">add oil</a>” in a way that might mean “add gasoline to your car” so you can continue to push hard and do what you need to do. In a general sense, the sentiment is “stay strong” or “keep going.” <em>Jiāyóu</em> is a common phrase used to encourage someone if they are facing a challenge.</p> <p>As the city of Wuhan faces the life and death challenge of the coronavirus, <em>jiāyóu</em> works as a phrase that resonates with residents of a city struggling to survive.</p> <p>“Wuhan <em>jiāyóu</em>” (武汉! 加油!) is now the motto of Wuhan to keep spirits high in the face of this spreading pandemic.</p> <p style="text-align: center;"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://images.theconversation.com/files/312746/original/file-20200130-41485-17ocjao.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /> <span class="caption">A comment left on ‘The Guardian’s’ Youtube video of the ‘jiāyóu’ chants.</span> <span class="attribution"><span class="source">YouTube/The Guardian</span></span></p> <p>In addition to raising morale and giving a strong sign of life to a city that has been rendered a ghost town, the <em>jiāyóu</em> chants have also served another purpose: for the global media audience, it has helped to humanize the citizens of Wuhan.</p> <p><strong>Apocalyptic fear</strong></p> <p>Even with the exceptional stories like the reporting of “Wuhan <em>jiayou</em>” by <a href="https://www.bbc.com/news/world-asia-china-51276496">the BBC </a> and the <a href="https://www.theguardian.com/world/2020/jan/28/indoor-fishing-and-chanting-battles-how-chinas-quarantined-millions-are-keeping-busy"><em>Guardian</em></a>, western media <a href="https://drive.google.com/file/d/1i4fvH-EFDU_xzP-gt3OxZR0RGAvLqU5J/view">has been shown to</a> inevitably contribute to reducing the people at the core of these stories into numbers and statistics.</p> <p>So far, it seems, with a few exceptions, western mainstream media has focused on medical and scientific stories. The images and videos shared of Wuhan <a href="https://www.theguardian.com/science/2020/jan/27/china-coronavirus-who-to-hold-special-meeting-in-beijing-as-death-toll-jumps">are of a ravaged</a> and scary ghost town.

Many social media posters have engaged in <a href="https://twitter.com/SimuLiu/status/1222459446799921153?s=20">fear mongering</a>.

There is a risk that acts of solidarity like “Wuhan <em>jiāyóu</em>” could be co-opted by government bodies to shift attention or responsibility away from authorities.</p> <p>This type of co-option was observed in <a href="https://odihpn.org/blog/bayanihan-after-typhoon-haiyan-are-we-romanticising-an-indigenous-coping-strategy/">the exaggerated use of “resilience” and “survival” narratives</a> after Typhoon Haiyan in the Philippines to paint a picture of a rapidly recovering community doing well by being resourceful and helping each other.</p> <p>These narratives of community resilience pushed forth by official government messages can act to shift responsibility away from the state and international humanitarian organizations that have formal responsibilities in disaster risk reduction and recovery.</p> <p>Thus, Premier Li Keqiang was able to use the peoples’ chant, “Wuhan <em>jiāyóu</em>” to rally support in the grocery store. But he did not create a space for questions about accountability and government action. This is often the double-edged sword of community solidarity: it is powerful, but it can also be misused by the powerful. <!-- Below is The Conversation's page counter tag.

Newborn tested positive for coronavirus 30 hours after birth

<p>A 30-hour-old infant born in a Wuhan hospital has become the youngest person to catch the new coronavirus.</p> <p>The newborn’s mother was found to have contracted the virus before giving birth on February 2 at Wuhan Children Hospital. The baby’s case suggested that the new virus could be passed on to unborn children, scientists said.</p> <p>“This reminds us to pay attention to mother-to-child being a possible route of coronavirus transmission,” said Zeng Lingkong, the chief physician at the hospital’s neonatal department.</p> <p>The infected infant has no fever or cough but experienced shortness of breath, according to <em>CCTV</em>.</p> <blockquote class="twitter-tweet"> <p dir="ltr">An infant in <a href="https://twitter.com/hashtag/Wuhan?src=hash&amp;ref_src=twsrc%5Etfw">#Wuhan</a> has tested positive for the novel <a href="https://twitter.com/hashtag/coronavirus?src=hash&amp;ref_src=twsrc%5Etfw">#coronavirus</a> just 30 hours after birth, said the city's children's hospital, raising concerns that infection could be contracted in the womb <a href="https://t.co/j8FIdqKgAS">pic.twitter.com/j8FIdqKgAS</a></p> — People's Daily, China (@PDChina) <a href="https://twitter.com/PDChina/status/1225042136980230144?ref_src=twsrc%5Etfw">February 5, 2020</a></blockquote> <p>The hospital also confirmed a second case of a newborn showing symptoms 16 days after their birth. The baby’s mother and nanny were <a href="https://www.msn.com/en-au/news/world/newborn-infected-with-coronavirus-raising-fears-illness-can-be-transmitted-from-mother-to-unborn-baby/ar-BBZGdIh?li=AAgfYrC">found to be infected</a> in the days following the birth on 13 January. The infant is not in a critical condition, doctors said.</p> <p>“Whether it was the baby’s nanny who passed to the virus to the mother who passed it to the baby, we cannot be sure at the moment,” Zeng said.</p> <p>“But we can confirm that the baby was in close contact with patients infected with the new coronavirus, which says newborns can also be infected.”</p> <p>However, Stephen Morse, an epidemiologist at the Mailman School of Public Health at Columbia University, told <em><a href="https://www.businessinsider.com.au/wuhan-coronavirus-in-infant-born-from-infected-mother-2020-2?r=US&amp;IR=T">Business Insider</a></em> that an in-utero transmission was unlikely.</p> <p>“It’s more likely that the baby contracted the virus from the hospital environment, the same way healthcare workers get infected by the patients they treat,” Morse said.</p> <p>“It’s quite possible that the baby picked it up very conventionally – by inhaling virus droplets that came from the mother coughing.”</p> <p>More than 24,500 people around the world have now contracted the virus, with the death toll approaching 500.</p>

How does the Wuhan coronavirus cause serious illness?

<p>We usually think of viral respiratory infections, like the common cold, as mild nuisances that pass in a few days. But the Wuhan coronavirus has proven to be different. Of those infected, <a href="https://flutrackers.com/forum/forum/-2019-ncov-new-coronavirus/823378-2019-ncov-confirmed-case-list-by-country-w-links-to-sources-total-cases-17-382-total-deaths-362-as-of-11-25-pm-et-february-2-2020-disclaimer-we-do-not-endorse-any-of-these-numbers">around 2%</a> are reported to have died but the true mortality is unknown.</p> <p>There’s much we’re yet to learn about this new virus, but we know it often causes <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/pneumonia">pneumonia</a>, an infection of the lungs which produces pus and fluid and reduces the lungs’ ability to absorb oxygen.</p> <p>Of the first <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30211-7/fulltext">99 people with severe infection</a>, three-quarters had pneumonia involving both lungs. Around 14% appeared to have lung damage caused by the immune system, while 11% suffered from multi-organ system failure, or sepsis.</p> <p>Others are at risk of complications from being treated in hospitals, such as acquiring other infections.</p> <p>At this stage, we know some people develop only a mild infection, while others become critically ill, but the exact proportion of each is not yet clear.</p> <p>Overall, there are four key ways the Wuhan coronavirus can cause severe disease – and some can occur at the same time.</p> <p><strong>1. Direct viral damage</strong></p> <p>For the SARS (severe acute respiratory syndrome) coronavirus, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1829448/">direct viral damage</a> was probably the most common way the infection caused disease. This is likely the case with the Wuhan coronavirus.</p> <p>Early <a href="https://www.biorxiv.org/content/biorxiv/early/2020/01/26/2020.01.26.919985.full.pdf">studies</a> have found the Wuhan coronavirus attaches to a particular receptor found in lung tissue. This is like a lock and key mechanism allowing the virus to enter the cell, and is the same receptor the SARS coronavirus used.</p> <p>Viruses “hijack” the host cell’s mechanisms to make more copies of itself. Damage results from either viruses taking over the cell completely and causing it to die, or immune cells recognising the viral infection and mounting a defence, triggering cell death.</p> <p>If large numbers of cells die, then the affected organ can’t function effectively.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1829448/">Studies</a> from patients who died from SARS coronavirus showed the virus caused damage to not only the lungs, but also other organs in the body. <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30211-7/fulltext">Early research</a> suggests the Wuhan coronavirus can also damage other organs, including the kidneys.</p> <p><strong>2. Pneumonia</strong></p> <p>While we’re still piecing together the relationship between the Wuhan coronavirus and pneumonia, there’s much we can learn from influenza.</p> <p>Influenza is a virus but it commonly <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5481322/">leads to bacterial pneumonia</a> – this is what’s known as a secondary infection.</p> <p>It’s thought the influenza virus weakens the usual protective mechanisms of the lung, allowing bacteria to establish and multiply. This is especially true in children, older people and those with compromised immune systems.</p> <p>Secondary bacterial pneumonia is <a href="https://www1.health.gov.au/internet/main/publishing.nsf/Content/75F30C0D2C126CAECA2583940015EDE3/%24File/influenza_epidemiology_in_patients_admitted_to_sentinel_australian_hospitals_in_2017.pdf">more severe</a> than influenza alone – in hospitalised patients, around 10% of those with influenza and pneumonia die, compared to around 2% of those who don’t have pneumonia.</p> <p>The Wuhan coronavirus appears to cause pneumonia in two ways: when the virus takes hold in the lungs, and through secondary bacterial infections, however, the first way appears to be more common.</p> <p><strong>3. Sepsis</strong></p> <p><a href="https://jamanetwork.com/journals/jama/fullarticle/2492881">Sepsis</a> is a serious condition that can be caused by many infections.</p> <p>When we get an infection, we need to mount an immune response to fight off the pathogen. But an excessive immune response can cause damage and organ failure. This is what happens in the case of sepsis.</p> <p>Although it can be difficult to determine whether organ damage from the Wuhan coronavirus is a result of direct viral infection or indirect “collateral damage” from the immune system, <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30211-7/fulltext">initial reports suggested</a> around 11% of people severely ill with the Wuhan coronavirus experienced sepsis with multi-organ failure.</p> <p>So far no drugs or interventions have <a href="https://www.ncbi.nlm.nih.gov/m/pubmed/24581450/">been able to dampen this immune response</a>. Although several treatments have been proposed for Wuhan coronavirus, none have yet been shown to work.</p> <p><strong>4. Complications of hospital care</strong></p> <p>Finally, patients who require hospital care may have complications. These include infections from intravenous lines (for drips/medication) or urinary catheters (flexible tubes inserted into the bladder to empty it of urine), pneumonia, or non-infectious complications such as falls or pressure sores.</p> <p><a href="https://aricjournal.biomedcentral.com/articles/10.1186/s13756-019-0570-y">Studies</a> have found 10% of patients in hospital have some sort of health care-acquired infection, and around 5% have a pressure sore.</p> <p>Hospitals work hard to try to prevent these complications, by making sure health care workers disinfect their hands and other equipment. However, complications still occur, particularly in patients who are debilitated from long hospital stays.</p> <p>While most respiratory viral infections are mild, some can trigger serious complications, either directly or indirectly. It’s too early to tell how often this occurs with the Wuhan coronavirus. While we have initial data on those who were severely affected, many others may not have required medical care.<!-- Below is The Conversation's page counter tag.

Australian student shares update from inside Wuhan amid coronavirus outbreak

<p>A university student has shared what life under lockdown in Wuhan was like amidst the coronavirus outbreak.</p> <p>Australian National University student Helen Chen has been unable to leave the city of 11 million people after she travelled in to celebrate Chinese New Year with her family.</p> <p>Speaking in a video distributed by Reuters, Chen said she has not left her parents’ apartment since around a week ago.</p> <p>“There is literally no one outside. It’s pretty scary,” she said.</p> <p>“The last time I went out was probably a week ago, I think.</p> <p>“I wore a mask, most people were wearing masks and when my parents went out this morning to do groceries they wore masks as well.</p> <p>“I made sure that they brought hand sanitiser and they wore gloves just to be extra careful.”</p> <p>Chen said she was keeping busy by doing her university assignments while her father watched the Australian Open on TV.</p> <p>She also noted the ways people had responded to the outbreak.</p> <p>“Times like this sometimes bring out the worst in people as I have seen a lot of comments online but there are also good people around,” she said.</p> <p>“A lot of people are donating food and people are volunteering to drive doctors and nurses around … Sometimes we forget that there are just wonderful people out there who are willing to put themselves at risk of infection, and possibly even death, to help others.”</p> <p>In a <a rel="noopener" href="https://www.facebook.com/helecx/posts/3198588340156167" target="_blank">Facebook post</a> shared on Tuesday, Chen shared another update on life in the city.</p> <p>“We have enough fresh produce at home for a couple days since my parents went out again yesterday morning on a grocery run,” she wrote.</p> <p>“Most smaller neighbourhood supermarkets are closed but bigger designated supermarkets are open and the apparently the [government] is making sure they get multiple deliveries every day and prices are kept as per normal.</p> <p>“We’re more or less living our life like how we normally would, apart from the anxieties of infection and not being able to go out. But it’s all pretty mild stuff compared to what people directly involved are feeling. I do acknowledge I am speaking from a place of privilege, and my personal experience might not be the perfect reflection of the situation in Wuhan.”</p> <p>Chen also addressed the seemingly racist comments on social media which laid the blame on Chinese people for forgoing health and safety concerns. “I’ve seen reports of incidents where selfish individuals have knowingly put others in danger,” she wrote.</p> <p>“But again, it’s unfair to insist that they are an accurate reflection of Chinese people in general. Most of us are doing our part by respecting the quarantine, staying home, wearing masks when we really do have to go out, and donating in any way we are able to.”</p> <p>The coronavirus has so far taken more than 120 lives and infected more than 5,900 people in China.</p>

How contagious is the Wuhan coronavirus and can you spread it before symptoms start?

<p>Cases of the Wuhan coronavirus have increased dramatically over the past week, prompting concerns about how contagious the virus is and how it spreads.</p> <p>According to the <a href="https://www.who.int/emergencies/diseases/novel-coronavirus-2019/situation-reports">World Health Organisation</a>, 16-21% of people with the virus in China became severely ill and 2-3% of those infected have died.</p> <p>A key factor that influences transmission is whether the virus can spread in the absence of symptoms – either during the incubation period (the days before people become visibly ill) or in people who never get sick.</p> <p>On Sunday, <a href="https://www.bbc.com/news/world-asia-china-51254523">Chinese officials said</a> transmission had occurred during the incubation period.</p> <p>So what does the evidence tell us so far?</p> <p><strong>Can you transmit it before you get symptoms?</strong></p> <p>Influenza is the <a href="https://www.infectiousdiseaseadvisor.com/home/topics/respiratory/influenza/transfluas-study-asymptomatic-influenza-transmission-in-acute-health-care/">classic example</a> of a virus that can spread when people have no symptoms at all.</p> <p>In contrast, people with <a href="https://www.nhs.uk/conditions/sars/">SARS</a> (severe acute respiratory syndrome) only spread the virus when they had symptoms.</p> <p>No published scientific data are available to support China’s claim transmission of the Wuhan coronavirus occurred during the incubation period.</p> <p>However, <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30154-9/fulltext">one study published in the Lancet medical journal showed</a> children may be shedding (or transmitting) the virus while asymptomatic. The researchers found one child in an infected family had no symptoms but a chest CT scan revealed he had pneumonia and his test for the virus came back positive.</p> <p>This is different to transmission in the incubation period, as the child never got ill, but it suggests it’s possible for children and young people to be infectious without having any symptoms.</p> <p>This is a concern because if someone gets sick, you want to be able to identify them and track their contacts. If someone transmits the virus but never gets sick, they may not be on the radar at all.</p> <p>It also makes airport screening less useful because people who are infectious but don’t have symptoms would not be detected.</p> <p><strong>How infectious is it?</strong></p> <p>The Wuhan coronavirus epidemic began when people exposed to an <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30183-5/fulltext">unknown source at a seafood market</a> in Wuhan began falling ill in early December.</p> <p>Cases remained below 50 to 60 in total until around January 20, when numbers surged. There have now been <a href="https://flutrackers.com/forum/forum/-2019-ncov-new-coronavirus/823378-2019-ncov-confirmed-case-list-by-country-w-links-to-sources-total-cases-4-576-total-deaths-106-as-of-9-40-et-january-27-2020-disclaimer-we-do-not-endorse-any-of-these-numbers">more than 4,500 cases – mostly in China – and 106 deaths</a>.</p> <p>Researchers and public health officials determine how contagious a virus is by calculating a reproduction number, or R0. The R0 is the average number of other people that one infected person will infect, in a completely non-immune population.</p> <p>Different experts have <a href="https://www.imperial.ac.uk/mrc-global-infectious-disease-analysis/news--wuhan-coronavirus/">estimated</a> the R0 of the Wuhan coronavirus is anywhere from 1.4 to over five, however the <a href="https://www.bmj.com/content/bmj/368/bmj.m308.full.pdf">World Health Organisation believes</a> the RO is between 1.4 and 2.5.</p> <p>If the R0 was higher than 2-3, we should have seen more cases globally by mid January, given Wuhan is a travel and trade hub of 11 million people.</p> <p><strong>How is it transmitted?</strong></p> <p>Of the person-to-person modes of transmission, we fear respiratory transmission the most, because infections spread most rapidly this way.</p> <p>Two kinds of respiratory transmission are through large droplets, which is thought to be short-range, and airborne transmission on much smaller particles over longer distances. Airborne transmission is the most difficult to control.</p> <p>SARS was considered to be transmitted by contact and over short distances by droplets but can also be transmitted through smaller aerosols over long distances. In Hong Kong, <a href="https://academic.oup.com/cid/article/58/5/683/365793">infection was transmitted</a> from one floor of a building to the next.</p> <p>Initially, most cases of the Wuhan coronavirus were assumed to be from an animal source, localised to the seafood market in Wuhan.</p> <p>We <a href="https://jglobalbiosecurity.com/articles/51/">now know</a> it can spread from person to person in some cases. The Chinese government announced it can be spread by touching and contact. We don’t know how much transmission is person to person, but we have some clues.</p> <p>Coronaviruses are respiratory viruses, so they can be found in the nose, throat and lungs.</p> <p>The amount of Wuhan coronavirus appears to be <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30183-5/fulltext">higher in the lungs</a> than in the nose or throat. If the virus in the lungs is expelled, it could possibly be spread via fine, airborne particles, which are inhaled into the lungs of the recipient.</p> <p><strong>How did the virus spread so rapidly?</strong></p> <p>The continuing surge of cases in China since January 18 – despite the lockdowns, extended holidays, travel bans and banning of the wildlife trade – could be explained by several factors, or a combination of:</p> <ol> <li> <p>increased travel for New Year, resulting in the spread of cases around China and globally. Travel is a major factor in the spread of infections</p> </li> <li> <p>asymptomatic transmissions through children and young people. Such transmissions would not be detected by contact tracing because health authorities can only identify contacts of people who are visibly ill</p> </li> <li> <p>increased detection, testing and reporting of cases. There has been increased capacity for this by doctors and nurses coming in from all over China to help with the response in Wuhan</p> </li> <li> <p>substantial person-to-person transmission</p> </li> <li> <p>continued environmental or animal exposure to a source of infection.</p> </li> </ol> <p>However, with an incubation period as short as <a href="https://www.who.int/docs/default-source/coronaviruse/situation-reports/20200127-sitrep-7-2019--ncov.pdf?sfvrsn=98ef79f5_2">one to two days</a>, if the Wuhan coronavirus was highly contagious, we would expect to already have seen widespread transmission or outbreaks in other countries.</p> <p>Rather, the increase in transmission is likely due to a combination of the factors above, to different degrees. The situation is changing daily, and we need to analyse the transmission data as it becomes available.<!-- Below is The Conversation's page counter tag.

Banana Boat disgrace as 50+ sunscreens fail new lab tests

<p><span>A new lab test has found that seven Banana Boat sunscreens have failed to meet the advertised SPF 50+ claims.</span></p> <p><span>The tests were conducted by Eurofins Dermatest according to international standards and each sunscreen spray was tested 10 times. The results of the tests could lead to a potential filing of a class action lawsuit by an Australian mother and her five children.</span></p> <p><span>Bannister Law is taking registrations against Edgewell Personal Care Australia, the manufacturer of Banana Boat, after laboratory tests found its sunscreen sprays average ratings were SPF20 or less instead of the advertised SPF50+.</span></p> <p><span>"All seven aerosol varieties we tested fell well short of the marketed SPF 50+," said Charles Bannister, founder and principle of Bannister Law.</span></p> <p><span>"To claim SPF 50+, products need to test greater that 60+."</span></p> <p><span>The best performing sunscreen, Banana Boat Kids Clear Sunscreen Spray SPF 50+, achieved an average SPF rating of 20.2. The worst performing sunscreen, Banana Boat SunComfort Clear Sunscreen Spray SPF 50+, achieved an SPF rating of 10.7</span></p> <p style="text-align: center;"><span><img width="500" height="274" src="https://oversixtydev.blob.core.windows.net/media/7264633/1_500x274.jpg" alt="1 (47)"/><br /></span></p> <p><span>Leading the class action is a mother and her five children who claim to have been repeatedly burned despite using Banana Boat products, Ultra Clear Sunscreen Spray SPF 50+ and Kids Clear Sunscreen Spray SPF 50+.</span></p> <p><span>All of her five children are believed to be under the age of 10.</span></p> <p><span>Edgewell Personal Care rejected the test results and described them as “anomalous”.</span></p> <p><span>"All Banana Boat products meet the SPF claim as labelled on the pack," a company spokesperson tells CHOICE.</span></p> <p><span>"These results are entirely inconsistent with the testing we have conducted at Edgewell's reputable labs, in accordance with the Australian mandatory standard as regulated by the TGA."</span></p> <p><span>The Therapeutic Goods Administration (TGA), the Department of Health body responsible for regulating sunscreens, said in May they started investigating aerosol sunscreen following public concerns.</span></p> <p><span>"TGA undertook preliminary testing to investigate their delivery rates," a spokesperson tells us. "We found the amount of sunscreen delivered per second differed between brands.</span></p> <p><span>"It is important consumers ... 'apply liberally' to ensure proper coverage of the sunscreen."</span></p> <p><span>The class action lawsuit is in early stages, but Charles Bannister said it will most likely go ahead.</span></p> <p><span>"I don't see any reason why this class action won't proceed," he told CHOICE. "I would encourage the makers of Banana Boat to resolve any issues."</span></p> <p><span>Sunscreen SPF claims and regulation were called into question last summer as photos of people who were burned despite applying sunscreen went viral.</span></p> <p><span>Since 2015, the category has come under scrutiny after a CHOICE investigation found four out of six sunscreens did not meet advertised SPF 50+ claims. </span></p> <p><span>Do you own or have you used any of these Banana Boat products and still suffered from sunburn? Tell us in the comments below. </span></p>
