He is vaccinated and boosted and he is experiencing mild symptoms. He will be returning to Delaware where he will self-isolate and will continue to carry out all of his duties fully during that time," Press Secretary Karine Jean-Pierre said in a statement provided to Business Insider. "The White House will provide regular updates on the President's status as he continues to carry out the full duties of the office while in isolation."The White House also provided a note from Biden's doctor that said the president tested after having a runny nose, cough, and general malaise. The note said Biden was experiencing mild symptoms and that his respiratory rate, temperature, and blood oxygen levels were normal. It also said he had received a first dose of Paxlovid.Biden, 81, has been in Nevada since Monday night and was set to speak at a conference for UnidosUS in Las Vegas on Wednesday.Janet Murguía, CEO of UnidosUS, told conference attendees that Biden tested positive for COVID-19 after the president was an hour and a half late to his planned speaking event, according to <a target="_blank" class="" href="https://www.cnn.com/2024/07/17/politics/joe-biden-tests-positive-covid-19/index.html">CNN</a>."I was just on the phone with President Biden. And he shared his deep disappointment at not being able to join us this afternoon. The president has been at many events, as we all know, and he just tested positive for COVID," Murguía said at the conference.Biden departed Nevada, a key battleground state for the election in November, on Air Force One on Wednesday, telling reporters at the scene, "I feel good," according to the <a target="_blank" class="" href="https://apnews.com/article/biden-covid-las-vegas-ff29bb071f18b993d20dedccbe2c8fbf">Associated Press</a>.

Biden tests positive for COVID-19

A recent study suggests that lingering <keyword id="23667455" type="General" weightage="20" keywordseo="SARS-CoV-2-proteins" source="keywords">SARS-CoV-2 proteins</keyword> in the blood of <keyword id="20537242" type="General" weightage="100" keywordseo="long-COVID" source="keywords">long COVID</keyword> sufferers could be a key factor in their ongoing symptoms. This discovery offers new insights into the complex nature of long COVID and potentially points towards new treatment strategies. Researchers at Harvard-affiliated <keyword id="23667458" type="General" weightage="20" keywordseo="Brigham-and-Womens-Hospital" source="keywords" meta.keywordsubtype="org" meta.entityname="Brigham and Women’s Hospital" meta.hostid="261" meta.entityid="Brigham and Women’s Hospital">Brigham and Women’s Hospital</keyword> analysed blood samples from 706 individuals who had previously tested positive for COVID-19. They found that those experiencing a wide range of long COVID symptoms were twice as likely to have traces of SARS-CoV-2 proteins in their blood compared to those without symptoms. The study, published in the journal <keyword id="23667460" type="General" weightage="20" keywordseo="clinical-microbiology" source="keywords">Clinical Microbiology</keyword> and Infection, focused on individuals with long COVID symptoms affecting three major body systems: cardiopulmonary, musculoskeletal, and neurologic. A staggering 43% of these patients tested positive for viral proteins within 1 to 14 months of their initial COVID infection. These findings suggest that a persistent viral infection may be contributing to long COVID symptoms in some patients. If this is the case, <keyword id="23667457" type="General" weightage="20" keywordseo="antiviral-treatments" source="keywords">antiviral treatments</keyword> could potentially alleviate their suffering. The study’s lead author, Zoe Swank, emphasised the importance of identifying patients who may benefit from such interventions. However, the researchers also noted that persistent viral proteins were not detected in all long COVID patients. This suggests that other factors, such as <keyword id="21736950" type="General" weightage="20" keywordseo="immune-system-dysfunction" source="keywords">immune system dysfunction</keyword>, may also play a role in the development of long COVID symptoms. To better understand the mechanisms underlying long COVID, researchers are conducting further studies to analyse blood samples and symptom data from larger groups of patients. These efforts aim to identify specific factors that may predispose individuals to persistent viral infections and long COVID symptoms. The discovery of a potential <keyword id="23667459" type="General" weightage="20" keywordseo="viral-reservoir" source="keywords">viral reservoir</keyword> in long COVID patients offers hope for the development of targeted treatments. By addressing the underlying cause of symptoms, antiviral medications could provide relief for many individuals suffering from this debilitating condition. As research continues, a clearer picture of long COVID and its potential treatments is emerging, offering hope for a future where this persistent illness can be effectively managed. <div type="Article" hostid="261" msid="105896840" title="Covid virus can persist in lungs for up to two years: Study" mstype="2" mssubtype="0"></div>

SARS-CoV-2 proteins have been found hiding in blood of long COVID patients. Can this explain the persistent infection?

After years of intensified focus on <keyword id="19897423" type="General" weightage="20" keywordseo="COVID-19" source="keywords">COVID-19</keyword>, <keyword id="19992404" type="General" weightage="100" keywordseo="Tuberculosis" source="keywords">tuberculosis</keyword> (TB) has once again emerged as the leading <keyword id="20564668" type="General" weightage="20" keywordseo="infectious-disease" source="keywords">infectious disease</keyword> killer worldwide. This resurgence is a sobering reminder that despite our pandemic response, TB has continued to claim lives, especially in low- and middle-income countries (LMICs), where resources are often stretched thin. According to the latest <keyword id="19896311" type="General" weightage="20" keywordseo="World-Health-Organization" source="keywords" meta.keywordsubtype="org" meta.entityname="World Health Organization" meta.hostid="261" meta.entityid="World Health Organization">World Health Organization</keyword> (<keyword id="19895006" type="General" weightage="20" keywordseo="WHO" source="keywords">WHO</keyword>) report, approximately 8.2 million people were diagnosed with TB in 2023, marking the highest number of cases recorded since global monitoring began in 1995. <h2><keyword id="19895063" type="General" weightage="20" keywordseo="India" source="keywords">India</keyword> and Indonesia</h2>The recent spike in TB cases is largely driven by increases in two countries — India and Indonesia. Together, they accounted for 45% of the global rebound in TB diagnoses between 2021 and 2023, underscoring their critical role in the worldwide fight against TB. Three other countries, the Philippines, Nigeria, and Pakistan, also made significant contributions, collectively accounting for another 32% of the increase. This means that more than three-quarters of the global resurgence in TB can be traced to these five countries alone. One key reason for these increases is the “backlog” effect created by COVID-19 disruptions. During the pandemic, healthcare systems in many countries, including India and Indonesia, had to shift focus to COVID-19, which delayed TB diagnosis and treatment. In 2023, as these countries ramped up recovery efforts, many previously undetected TB cases surfaced, creating an apparent spike in reported numbers. This trend highlights the importance of sustainable healthcare infrastructure capable of handling simultaneous health crises. <h2>Gaps in TB case detection</h2>Despite the daunting increase in TB cases, some countries have made notable progress in <keyword id="23741990" type="General" weightage="20" keywordseo="treatment-coverage" source="keywords">treatment coverage</keyword>. Among the 30 high-burden TB countries, those with the highest levels of treatment coverage in 2023 included Brazil, India, Mozambique, Papua New Guinea, Sierra Leone, Uganda, and Zambia, with coverage rates surpassing 80%. India’s <keyword id="21052657" type="General" weightage="20" keywordseo="national-tuberculosis-elimination-program" source="keywords">National Tuberculosis Elimination Program</keyword> (NTEP) has undoubtedly played a pivotal role in this, aiming to eradicate TB by 2025 — five years ahead of the global target. By focusing on expanded testing, improved diagnostic tools, and more accessible treatment options, India has achieved high treatment coverage levels despite the challenges. <div type="Article" hostid="261" msid="114732986" title="Air Quality Alert: Nearly 30% of asthma cases tied to fine particulate matter exposure from bad air" mstype="2" mssubtype="0"></div>However, a significant treatment gap remains. The difference between estimated TB incidence and actual diagnoses still affects millions, especially in countries with large populations like India, Indonesia, Pakistan, China, and Myanmar. These five nations together account for about 50% of the global gap in reported TB cases, with India alone responsible for 16% of the discrepancy. <h2>India’s unique position in the global TB fight</h2>As the nation with the largest share of global TB cases, India has a unique and critical responsibility in addressing the disease. The high TB burden in India is tied to several factors, including undernutrition, poverty, and limited access to healthcare in rural areas. Moreover, with 26% of all TB cases globally, India’s battle against TB will significantly impact the global fight. The government’s financial support for TB-affected households also aims to reduce the economic burden of treatment. However, challenges remain, especially with <keyword id="22004277" type="General" weightage="20" keywordseo="multidrug-resistant-TB" source="keywords">multidrug-resistant TB</keyword> (MDR/RR-TB). While treatment success rates for MDR/RR-TB have reached 68%, diagnosing and treating all drug-resistant cases is an ongoing challenge. In 2023, India’s coverage of preventive treatment for TB among people living with HIV and close contacts of TB patients also saw improvements, but underfunding continues to limit the full scope of TB elimination efforts. <h2>Global funding gaps</h2>Global funding shortages for <keyword id="21039793" type="General" weightage="20" keywordseo="TB-prevention" source="keywords">TB prevention</keyword> and treatment are a significant hindrance to progress. Only $5.7 billion of the targeted $22 billion in funding was met in 2023, and for LMICs — where nearly all of the TB burden lies — the available funding falls well short of their needs. The United States remains the largest bilateral donor, and contributions from the Global Fund to Fight AIDS, Tuberculosis, and Malaria are crucial. However, these funds are not enough to meet essential TB service requirements, leaving healthcare systems under-resourced. <div type="Article" hostid="261" msid="114646545" title="Doctors struggle to treat long Covid patients in India; researchers point to inadequate studies" mstype="2" mssubtype="0"></div>Even in 2022, only one-fifth of the $5 billion target for research funding was achieved, as per the report. This underfunding hampers the development of improved diagnostics, drugs, and vaccines, which are crucial to TB prevention and treatment. Moreover, many of the drivers of TB are related to social factors, such as undernutrition, smoking, alcohol use, and diabetes, making it imperative to address these root causes. For instance, almost half of the TB-affected households globally face what the WHO calls "catastrophic costs" in seeking treatment. This burden is particularly severe in India, where low-income families often forgo treatment due to financial constraints. As WHO’s Director-General Dr Tedros Adhanom Ghebreyesus puts it, "The fact that TB still kills and sickens so many people is an outrage, when we have the tools to prevent it, detect it, and treat it.” The WHO’s Global tuberculosis report 2024 can be accessed <a href="https://www.who.int/teams/global-tuberculosis-programme/tb-reports/global-tuberculosis-report-2024">here</a>.

Tuberculosis dethrones COVID-19 as world’s top infectious killer again; Half of all new cases from India, Indonesia

With hundreds of finger-licking preparations, India loves chicken in a way that may be indescribable to a non-resident. However, with the way things are progressing in the avian world, we could soon see a surge in disdain for the delectable meat, and in perhaps the same way the masses denounced bats during the COVID-19 pandemic. In a surprising and alarming twist, <a href="http://dx.doi.org/10.1038/s41586-024-07849-4">new research</a> has found that <keyword id="20633083" type="General" weightage="20" keywordseo="avian-influenza" source="keywords">avian influenza</keyword>, or <keyword id="20396857" type="General" weightage="20" keywordseo="bird-flu" source="keywords">bird flu</keyword>, has jumped from birds to dairy cattle across many parts of the United States. Initially detected in wild birds, the <keyword id="21348322" type="General" weightage="20" keywordseo="H5N1" source="keywords">H5N1</keyword> had led to symptoms like reduced appetite, respiratory distress, and a significant drop in milk production. "This is one of the first times that we are seeing evidence of efficient and sustained mammalian-to-mammalian transmission of highly pathogenic avian influenza H5N1," said Diego Diel, a virology expert who has written extensively about the topic. As per the new report, significant amounts of the virus has now been identified in the mammary glands of infected cows, meaning their milk itself has the ability to infect others. Researchers have even documented cases where cats and a raccoon became infected, likely from consuming the raw milk from infected cows. Although pasteurisation has shown the ability to kill the virus, the newfound ability to jump from cows to other mammals remains particularly troubling, especially considering how reliant we are on cow products such as beef and milk. <h2>Human cases and <keyword id="22448349" type="General" weightage="20" keywordseo="pandemic-potential" source="keywords">pandemic potential</keyword></h2>If you’re feeling comfortable in the thought that the virus has some ways to go before humans need to be concerned, you might want to think again. So far, 11 human cases have already been reported in the US, primarily linked to cattle and <keyword id="20524711" type="General" weightage="20" keywordseo="poultry-farms" source="keywords">poultry farms</keyword>. While these cases have resulted in mild symptoms, experts worry that the virus could mutate, enhancing its transmissibility among humans. This possibility is a significant concern for scientists and health authorities. <div type="Article" hostid="261" msid="109054967" title="Scientists warn of bird flu pandemic that could be &amp;#39;100 times worse&amp;#39; than COVID after rare human case found in US" mstype="2" mssubtype="0"></div>Further, as viruses do, H5N1 is already evolving at a rapid pace. A <a href="https://dx.doi.org/10.1101/2024.07.14.603367">separate study </a>led by researchers at UNC Charlotte found that the latest variants of H5N1 are getting better at evading antibodies, including those in humans. According to the researchers, these mutations could potentially lead the virus towards pandemic status if it continues to adapt and spread among mammals. <h2>Will developing nations be able to cope?</h2>Given these developments, continuous monitoring of the virus in both animals and humans is critical. The US Department of Agriculture has funded H5N1 testing programs to detect and manage outbreaks early. Enhanced biosecurity measures and quarantine protocols will undoubtedly be critical to prevent the virus from spreading to pandemic levels. However, this is a task much easier said than done for developing countries, who often lack the infrastructure and resources needed for such robust surveillance and response. Many of these countries have limited access to advanced diagnostic tools, vaccines, and antiviral treatments. This disparity leaves large portions of the global population vulnerable to the spread of H5N1. <div type="Article" hostid="261" msid="110941217" title="WHO confirms human case of bird flu in India! H9N2 virus detected in a four-year child in West Bengal" mstype="2" mssubtype="0"></div>The World Health Organization has repeatedly stressed the need for global cooperation and support to strengthen health systems in underprepared regions. Without adequate resources, these countries may struggle to detect and contain the virus, potentially allowing it to spread unchecked. This not only endangers local populations but also increases the risk of a global pandemic. The implications of these studies are clear: the H5N1 virus is moving closer to pandemic potential. As it spreads among mammals, the risk of it adapting to humans increases. The world needs to prepare now to avoid being caught off guard, as was the case with the COVID-19 pandemic.

<ul class="summary-list"><li>Forget friendship bracelets — some Swifties are calling Covid-19 their new concert souvenirs.</li><li>Some fans who got COVID-10 after attending her Eras Tour are calling it a "gift" from "Mother."</li></ul>It's been years since the pandemic times of COVID-19 lockdowns and the era of mandated masking. But while the virus is still circulating, some Swifties have become wildly optimistic about what it means to catch an infection at one of their idol's concerts. So much so that some Swifties on social media are playfully dubbing the COVID-19 infection they think they got from her concerts a "souvenir" and a "gift" from "Mother."A post on X from a Spanish Taylor Swift fan account asked followers: "Did you go to <a target="_blank" class="css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-1loqt21" href="https://x.com/hashtag/MadridTStheErasTour?src=hashtag_click">#MadridTStheErasTour</a> and take COVID, a virus, or a cold with you as a souvenir?

People in the poll's comments section described their symptoms and showed their positive COVID-19 tests — but also raved about how they thought it was worth it. The poll has been viewed nearly 144,000 times at press time.One X user <a target="_blank" href="https://x.com/RaquellvsRhett/status/1797947023641247766">commented</a>: "Going to Taylor's concert has meant losing my voice, losing my mental health and, well, my health in general, I'm more dead than alive (but I would go to the concert a thousand more times)."Earlier in February, an Australian concertgoer posted a TikTok of herself dressed up in her concert outfit and glam makeup. The video then cut straight to her holding up a positive COVID-19 test kit in bed. She captioned the post: "The Eras Tour souvenir no ones talking about. if youre heading to the sydney shows this weekend, wash your hands regularly!"However, other X users have voiced their disbelief at Swifties calling the virus a souvenir.One X user <a target="_blank" href="https://x.com/pot8um/status/1799513266265166174?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1799513266265166174%7Ctwgr%5E823e04af52763fad2f3a84db8d34b05f9516778a%7Ctwcon%5Es1_&amp;ref_url=https%3A%2F%2Fmuse.insider.com%2Fstory%2F666a622b074e87bb00f6cf0e">wrote:</a> "Taylor Swift's concert attendees are calling their Covid infections 'souvenirs' and 'gifts' from 'Mother,' and I'm supposed to NOT wanna launch myself into the sun???"Concerts have gained notoriety as COVID-19 superspreader events.

At first, there was little research on whether they could detect COVID, too, but a new research review has found a large body of evidence suggesting how helpful dogs can be in diagnosing the infectious illness. The authors of the new review, published last month in the <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.degruyter.com/document/doi/10.1515/jom-2023-0104/html">Journal of Osteopathic Medicine</a>, looked at 29 studies — including more than 30,000 samples across 31 countries. They said they found extensive evidence that trained dogs can accurately identify positive cases of COVID-19 through smell, which could be a less-invasive and more environmentally-friendly testing strategy than relying on plastic kits and disposable swabs. In some cases, dogs were able to identify COVID-19 infections in patients who had a viral load too low for other tests to work, the review found.The specially-trained canines could also diagnose quicker than other testing methods, after just a quick sniff of a person, and could also flag the virus in sweat samples in a process that takes only minutes. Dogs have incredibly sensitive noses that make them uniquely suited to sniffing out disease, according to Tommy Dickey, co-author of the paper, professor emeritus at UC Santa Barbara, and a certified <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.insider.com/guides/health/mental-health/emotional-support-animal">therapy dog</a> handler."They can detect the equivalent of one drop of an odorous substance in 10.5 Olympic-sized swimming pools," Dickey said in a press release. "For perspective, this is about three orders of magnitude better than with scientific instrumentation."And when it comes to snooting out COVID, all dogs are good dogs, according to the review. While scent dogs like hounds would be ideal, studies found that weeks of training could turn dogs of different ages, breeds, and backgrounds into virus-detecting pros. Diagnostics could even be a career option for rehabilitating troubled pups, as one study found a so-called "problem" pit bull from an abusive home got a fresh start as a COVID detector. Still, there are some logistical challenges to training and deploying the dogs on a large scale before we can toss out our test kits in favor of <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.insider.com/guides/health/mental-health/benefits-of-having-a-dog">four-legged friends</a>, according to the researchers."There's quite a bit of research, but it's still considered by many as a kind of a curiosity," Dickey said.

<ul><li>A new COVID-19 testing is being developed to help people easily get results and without spending too much.</li><li>The smaRT-LAMP testing system uses basic lab equipment and a smartphone app.</li><li>It’s said to produce accurate results and even detect new COVID variants.</li></ul>Researchers at the University of California, Santa Barbara have developed a new<a href="https://www.businessinsider.in/science/health/news/harmony-covid-19-test-claims-to-deliver-results-in-less-than-20-minutes-and-with-97-accuracy/articleshow/89107312.cms"> COVID-19 testing system</a> that uses basic lab equipment and a smartphone app, and it is claimed to give results as accurate as of the standard PCR test. This COVID testing system is called “smaRT-LAMP” and it could be as cheap as $7. The COVID testing requires a smartphone, an app called “Bacticount” and a test kit, according to a <a href="https://gizmodo.com/researchers-develop-cheap-covid-test-for-smartphones-1848443324">report</a> by Gizmodo. It requires a person’s saliva that is placed on the test kit and a reactive solution is added to it so that it can detect any viral RNA that could be present in the saliva sample. The sample is then covered with a cardboard box that has an LED light on top. The smartphone’s camera is then pointed at the LED lights and according to the colour reactions, it will be revealed if the sample being tested is <a href="https://www.businessinsider.in/india/news/covid-19-india-reports-over-200000-new-cases-and-959-fatalities-in-last-24-hours/articleshow/89236700.cms" data-type="tilCustomLink">COVID-19 </a>positive or not. If it’s a bright red light then the result is positive. One drawback of this COVID-19 test is that the Baticount app is currently compatible only with the Samsung Galaxy S9 series which is already four years old. Further development could add support for more smartphones otherwise the testing method won’t be convenient at all. The research is still very early though and it was conducted with samples of 50 people. The team is however confident that the results are promising, and smaRT-LAMP could help identify new COVID variants or even the flu. The COVID-19 testing kit is aimed at helping rural hospitals or places where there isn’t a proper testing system. It is also expected to be available as home testing kits.

Nonetheless, the UK's testing program has been held up as a model for other countries, and provides a glimpse into what Biden's plan could look like.<h2>How testing has worked in the US so far</h2>Here in the US, testing has not changed much in the last year-and-a-half.If I want a free COVID-19 <a href="https://www.businessinsider.com/when-to-take-at-home-rapid-covid-test-2022-1">rapid</a> or <a href="https://www.businessinsider.com/coronavirus-test-rapid-antigen-test-lateral-flow-pcr-explained-2021-1?r=US&amp;IR=T">PCR test</a> in New York, I have to go to a local clinic, which at times of high demand, involves an hours-long wait. My results are delivered via email, or, when it's not so busy, I'm told to wait 10 minutes to get the positive or negative verdict.

The first page gives you two free testing options:<ol><li>Click to order a PCR test if you have symptoms</li><li>Click to order a box of rapid tests if you don't have symptoms</li></ol>Either test can be home-delivered if you're not able to leave your home, or <a href="https://www.gov.uk/government/news/9-in-10-pharmacies-now-offering-free-rapid-coronavirus-covid-19-tests">picked up at a pharmacy</a>.As you scroll down, the page gives examples of what counts as a symptom, and recommends getting a rapid test if you've been exposed, regardless of how you feel."Even if you're vaccinated, you could still catch the virus or pass it on. Doing rapid tests helps to protect yourself and others," the website says. <h2>I ordered rapid tests to be home-delivered</h2><div type="image" title="NHS rapid testing website" height="1346" width="2072" msid="88886703" hostid="261"></div>Since none of us had symptoms, I clicked to order a box of "lateral flow" tests — the common term for rapid tests in the UK. (Lateral flow is the technical term for the technology used in rapid tests to detect viral proteins. Those proteins are called antigens, which is why these tests are also referred to as "antigen tests.")This page outlines what a rapid test is, and how to take it, then provides options for getting your tests: home delivery, pick up at a pharmacy, or pick up at a community center.The website says I can order one box of tests a day. Each box contains seven rapid tests, allowing people to test twice a week within a three-week timeframe. I clicked on the home delivery option, and was directed to <a href="https://www.gov.uk/order-coronavirus-rapid-lateral-flow-tests">a page on the UK government website</a> to make my order:<div type="image" title="Ordering rapid tests in England" height="398" width="988" msid="88886706" hostid="261"></div>I clicked through a series of questions, confirming I had no symptoms (if I did, I would be redirected to order a PCR test), and that I do not work for the NHS. I also had to enter my <a href="https://digital.nhs.uk/services/nhs-number">NHS number</a>, which records all my health information, and my parents' address. A minute later, I received a confirmation email that my tests were on the way.While it was seamless for me, many Brits say the process has been harder in recent weeks. Since the highly transmissible <keyword id="12616996" type="UNKNOWN" weightage="60" keywordseo="omicron" source="Orion">Omicron</keyword> variant emerged, many reported <a href="https://www.dailymail.co.uk/news/article-10328567/Brits-unable-hands-Covid-test-kits.html">being unable to order rapid tests at all</a>, hitting a page on the NHS website that said there were no delivery slots left, and to try again later.<h2>My box of rapid tests arrived the next day </h2><div type="image" title="My box of rapid tests arrived a day after I ordered them." height="828" width="1104" msid="88886708" hostid="261"></div><div type="image" title="The contents of my home-delivered rapid test" height="1319" width="1759" msid="88886710" hostid="261"></div>The day after I placed my order, I received a cardboard box containing swabs, testing tubes, and strips, plus waste bags and tube holders.

The <keyword id="8858345" type="General" weightage="60" keywordseo="sars-cov-2" source="Orion">SARS-CoV-2</keyword> virus is found in the lungs of certain individuals for up to 18 months after the infection, according to a study. One to two weeks after contracting COVID, the SARS-CoV-2 virus generally becomes undetectable in the upper respiratory tract. A team from the Institut Pasteur in collaboration with a French public research institute, the Alternative Energies and Atomic Energy Commission (CEA), conducted the study on lung cells in an animal model. The results, published in the journal Nature Immunology, show not only that SARS-CoV-2 is found in the lungs of certain individuals for up to 18 months after infection, but also that its persistence appears to be linked to a failure of innate immunity, the first line of defense against pathogens. Some viruses persist in the body in a discreet and undetectable manner after causing an infection. They remain in what are known as 'viral reservoirs', the researchers said. This is the case for HIV, which remains latent in certain immune cells and can reactivate at any time. It could also be the case for the SARS-CoV-2 virus which causes <keyword id="8763838" type="General" weightage="90" keywordseo="covid-19" source="Orion">COVID-19</keyword>, they said. "We observed that inflammation persisted for long periods in primates that had been infected by SARS-CoV-2. We therefore suspected that it could be due to the presence of the virus in the body," said Michaela Muller-Trutwin, Head of the Institut Pasteur's HIV, Inflammation and Persistence Unit. The study analysed biological samples from animal models that had been infected by the virus. Initial results from the study indicate that viruses were found in the lungs of some individuals six to 18 months after infection, even though the virus was undetectable in the upper respiratory tract or blood. The researchers also found that the amount of persistent virus in the lungs was lower for the Omicron strain than for the original SARS-CoV-2 strain. "We were really surprised to find viruses in certain immune cells - alveolar macrophages - after such a long period and when regular PCR tests were negative," said Nicolas Huot, first author of the study and researcher in the Institut Pasteur's HIV, Inflammation and Persistence Unit. "What's more, we cultured these viruses and were able to observe, using the tools we developed to study HIV, that they were still capable of replicating," Huot said. To understand the role of innate immunity in controlling these viral reservoirs, the scientists then turned their attention to NK (natural killer) cells. "The cellular response of innate immunity, which is the body's first line of defense, has been little studied in SARS-CoV-2 infections until now," said Muller-Trutwin. "Yet it has long been known that NK cells play an important role in controlling viral infections," the researcher said. The study shows that in some animals, macrophages infected with SARS-CoV-2 become resistant to destruction by NK cells, while in others, NK cells are able to adapt to infection (known as adaptive NK cells) and destroy resistant cells, in this case macrophages. The study sheds light on a mechanism that may explain the presence of viral reservoirs. While individuals with little or no long-term virus had adaptive NK cell production, individuals with higher levels of virus had not only an absence of adaptive NK cells, but also a reduction in NK cell activity, the researchers added.

<ul class="summary-list"><li>NASA was originally supposed to help OceanGate build and test a model of its carbon fiber hull.</li><li>But internal NASA emails show that the COVID-19 pandemic shut those plans down. </li></ul>NASA was originally supposed to help OceanGate build the <a href="https://www.businessinsider.com/titanic-sub-photos-suggest-carbon-fiber-hull-to-blame-expert-says-2023-6">controversial carbon fiber hull</a> for its submersible, but the plan was scrapped because of the COVID-19 pandemic, according to internal emails and a contract obtained by Insider. OceanGate's Titan submarine imploded in June on its way to the Titanic wreckage on the North Atlantic seafloor, killing all five passengers.<a href="https://www.insider.com/stockton-rush-glue-oceangate-titanic-sub-carbon-fiber-hull-2023-7#:~:text=The%20Titan%20sub%20imploded%20last,resulted%20in%20the%20catastrophic%20implosion.">Experts told Insider</a> that photos of the submersible's wreckage indicate the implosion may have been caused by a failure of the sub's experimental carbon fiber hull.OceanGate's use of the material in a submarine hull was new, but dangerous, experts said, since carbon fiber is more likely to succumb to pressure than more commonly-used materials like titanium.OcenGate first announced in a February 2020 press release that NASA's Marshall Space Flight Center in Huntsville, Alabama would "serve as the facility where the development and manufacturing" of OceanGate's carbon fiber hull would be completed. "This design effort is key to OceanGate completing its latest Cyclops-class submersible that is intended to dive to 6,000 meters (19,800 feet) with five crewmembers on board," the company wrote in the 2020 press release.<h2>Internal emails show NASA's reaction</h2>The contract between NASA and OceanGate, signed in early 2020, specified that NASA would manufacture a scale model of OceanGate's carbon fiber-hulled Titan submersible, and perform "ultrasonic testing" on the model "to ensure quality build," according to a copy of the contract obtained through a public records request.OceanGate, the contract said, would provide carbon fiber material for the model's construction.But after OceanGate's Titan sub got lost at sea in June, NASA staff were left to address the agency's connection to the controversial sub company, according to internal NASA emails obtained by Insider through a public records request. In one email, a NASA staff member wanted to make sure other staff knew that while NASA had originally agreed to help OceanGate build a "scale model" of the hull, it had not agreed to help build the "operational unit" itself. And then, the employee clarified in the email, COVID-19 prevented NASA from ever actually helping OceanGate build or test the scale model. "COVID struck and this activity was not deemed mission critical and personnel were not allowed onsite," the email says. "Oceangate was schedule critical and arranged for commercial entities in their home state of WA to execute the fabrication. While we did provide engineering input Oceangate was the technical authority and made final decisions. We only operated in a consultant role."The employee noted in another email that his last contact with Oceangate was in October 2020.After the Titan sub's implosion and reports of OceanGate's controversial design techniques, other entities like the University of Washington and Boeing <a href="https://www.businessinsider.com/boeing-university-of-washington-deny-helping-design-oceangate-titan-submersible-2023-6">have denied ever helping</a> OceanGate design the sub.A spokesperson for OceanGate declined to comment. A spokesperson for NASA did not immediately return a request for comment.Internally, at least one OceanGate employee <a href="https://www.businessinsider.com/oceangate-titan-former-pilot-listed-safety-concerns-titanic-sub-2018-2023-7">raised concerns</a> about the use of carbon fiber in the hull. Former OceanGate pilot David Lochridge wrote in a report shared within the company that he believed the hull could come apart with repeated dives, and that the sub's hull integrity monitoring system would give a pilot only milliseconds of notice before the craft imploded, according to media reports and <a href="https://www.insider.com/titanic-submersible-only-warns-milliseconds-before-hull-failure-fired-executive-2023-6">court filings</a>.Lochridge also called for more testing of the hull before the sub went on deep-sea dives, according to court filings.
