In its study, nine dogs were able to identify positive coronavirus samples with 96 percent accuracy on average after three weeks of training. Researchers say using dogs can help catch people who are infected and don’t know it — otherwise known as asymptomatic carriers — before they spread the virus to others.
The U.S. State Department said on Monday it will boost its "Do Not Travel" guidance to about 80% of countries worldwide, citing "unprecedented risk to travelers" from the COVID-19 pandemic.
More than two dozen virologists, epidemiologists, and others responded to STAT's question about what they still most wanted to know. The questions answer a range of concerns with immunity, viral load, reactivation, mutation, children and more.
Last week, the CDC acknowledged what many of us have been saying for almost nine months about cleaning surfaces to prevent transmission by touch of the coronavirus: It’s pure hygiene theater.
As COVID-19 vaccinations increase drastically in the United States, experts are keeping a wary eye on the rising number of coronavirus variants.A recent survey of epidemiologists, virologists, and infectious disease specialists found that many worry new mutations of the coronavirus could render current vaccines useless within a year.
The coronavirus vaccines made by Moderna and Pfizer-BioNTech are proving highly effective at preventing symptomatic and asymptomatic infections under real-world conditions, federal health researchers reported on Monday.
Severe allergies should be added to the possible side effects of AstraZeneca's coronavirus vaccine after likely links were found to a number of cases in Britain, the EU's drug regulator said on Friday.
Five South Koreans have died in the last two days after receiving the Covid-19 vaccine produced by AstraZeneca, sparking a presidential response and contributed to rising global concerns about the dose. According to local media reports, the five who died – two on Wednesday and three on Thursday – all had significant pre-existing medical conditions.
Recently published data from the Office for National Statistics (ONS) has caused worry. The data suggest that 13% of under 11s and about 15% of 12- to 16-year-olds reported at least one symptom five weeks after a confirmed Covid-19 infection.
The study, published on Wednesday in the journal JAMA, analyzed 1,116 cases of young people who were treated at 66 hospitals in 31 states. Slightly more than half the patients had acute Covid-19, the predominantly lung-related illness that afflicts most adults who get sick from the virus, while 539 patients had the inflammatory syndrome that has erupted in some children weeks after they have had a typically mild initial infection.
This sites offers the cumulative number of COVID-19 vaccination doses administered per country. The data on COVID-19 vaccinations is updated each morning (London time), with the most recent official numbers up to the previous day.
Doctors across the country have been seeing a striking increase in the number of young people with the condition Braden had, which is called Multisystem Inflammatory Syndrome in Children or MIS-C. Even more worrisome, they say, is that more patients are now very sick than during the first wave of cases, which alarmed doctors and parents around the world last spring.
The Centers for Disease Control and Prevention’s official guidance is that vaccinated people need to keep masking, physical distancing and basically following all pre-vaccine precautions. Those eager to fly across the country to see loved ones might hesitate because they are warned against viewing vaccination as a “free pass to travel.”
I caught this virus before anyone had even died in Illinois. That was like a century ago, right? Now we’re talking about Year Two, vaccines, new variants, a new administration, but for me it’s still exactly the same. I’m always in this bed. I’m always in this room. I’ve been sick for the last 330 days.
Skin temperature isn't a reliable measure of whether someone has a fever, furthermore infected people don't always have a fever and forehead temperature is not the most reliable measure! Scans should instead focus on other parts of the body.
The coronavirus may remain in people’s brains after infection and trigger relapses in patients who thought they had recovered, according to a new study published in the journal Viruses.
There’s evidence from several small, and not-yet-peer-reviewed, studies that mutations in the South Africa variant — known as 501Y.V2 and already present in at least 23 countries — may have a higher risk of Covid-19 reinfection in people who’ve already been sick and still should have some immunity to the disease.
The research by Leicester University and the Office for National Statistics (ONS) also found that up to one in eight die of Covid-related complications. It found that out of 47,780 people discharged from hospital in the first wave, 29.4 per cent returned to hospital within 140 days and 12.3 per cent died.
As viruses replicate, they change, or mutate. Some mutations give these viral variants an edge, such as being better able to latch on to and infect human cells. That’s what scientists think happened with the coronavirus variant that swept through the U.K. recently and which is now showing up in states across the U.S.
Immunity to the novel coronavirus may last eight months or longer, according to a new study authored by respected scientists at leading labs, which found that individuals who recovered from the coronavirus developed “robust” levels of B cells and T cells (necessary for fighting off the virus) and “these cells may persist in the body for a very, very long time.”
Monoclonal antibodies — described as “unbelievable” by President Trump, who received the treatment this fall — are designed for patients newly diagnosed with covid-19, the disease caused by the coronavirus, who have a high risk of developing complications and becoming seriously ill.
Early in the pandemic, people were advised to disinfect everything they touched. But now that scientists understand more about how COVID-19 spreads, all that scrubbing down may have been overkill.
Although the coronavirus was initially thought primarily to cause respiratory distress, there is now ample evidence of many other symptoms, including neurological, cognitive and psychological effects, that could emerge even in patients who didn’t develop serious lung, heart or circulatory problems.
World Health Organization chief scientist Soumya Swaminathan told a virtual briefing Monday people who've been vaccinated for COVID-19 "need to take the same precautions" as those who haven't "till there's a certain level of herd immunity."
Although most pediatricians believe the eventual vaccination of children will be crucial to subduing the Covid virus, they’re split on how fast to move toward. Much of the debate centers on two issues: the degree of harm Covid-19 causes children, and the extent to which children are spreading the virus to their friends, teachers, parents, and grandparents.
British researchers said the new mutation can spread 70 percent faster than other variations of the coronavirus. Variations to the virus are nothing new, and experts say the novel coronavirus does not mutate as much as influenza, meaning it is less likely that a vaccine would need to be developed every year to keep up with the new strains.
Just as vaccines begin to offer hope for a path out of the pandemic, officials in Britain on Saturday sounded an urgent alarm about what they called a highly contagious new variant of the coronavirus circulating in England.
Health Secretary Matt Hancock said at least 60 different local authorities had recorded Covid infections caused by the new variant. He said the World Health Organization had been notified and UK scientists were doing detailed studies. He said there was "nothing to suggest" it caused worse disease or that vaccines would no longer work.

Even Though there is promising news about vaccines, and Pfizer has announced a vaccine that is 90% effective, scientist say what the vaccine is effective against is going to matter a lot for the timeline of the pandemic.
Most tests to determine if somebody has already been infected with COVID-19 check for antibodies, but a new study in Italy found that those tests are much less accurate than a new type that looks for a type of immune cell called a T cell.
The study by Arizona University has shown that high-quality antibodies are still being produced five to seven months after SARS-CoV-2 infection. Learn about how the immune response works.
A new simulation from the Fugaku supercomputer in Japan demonstrates how the seating arrangement can make a difference to how easily the coronavirus is transmitted to dining companions at the same table. Humidity seems to make a difference in transmission.
More people have died from the pandemic than initially reported. Looking at the excess deaths in the US during the first five months of the Pandemic we find excess deaths as a result of heart disease, alzheimer's and dementia not directly related to coronavirus.
WHO says the lockdowns are a good tactic in situations where the transmission is spiralling out of control and a threat that the health system will be overwhelmed. But they should not be used as the main strategy and the decision should be considered carefully.
Scientist have pinned down common gene variants that are linked to the most severe cases of COVID19 and the reason why some people get very sick and others show only mild symptoms. This discovery leads to discovery of existing drugs that could be repurposed to help sick patients.
A 25-year-old was infected twice with the coronavirus earlier this year, scientists in Nevada have confirmed. It is the first confirmed case of so-called reinfection with the virus in the U.S. and the fifth confirmed reinfection case worldwide.

They made an experiment by releasing droplets in a room to see how it spreads. They found that people in front of the room are more susceptible and at higher risk in a properly ventilated room. In a poorly ventilated room the entire room is at risk.
Passengers sat in window seats in the middle of an economy class cabin on a Qantas Airways flight in March were most at risk from contracting coronavirus, according to research by Australian scientists into that particular trip.
To date, the range and scope of verifiable research data linking cannabinoids with COVID-19 prevention is highly limited; however, novel approaches to the prevention of COVID-19 include a single study examining the possibility of incorporating CBD into oral solutions, such as mouthwashes and throat gargling liquids, with a view to ‘lowering or modulating ACE2 levels in high-risk tissues’.
A flurry of recent studies has shown that people with extra weight are more susceptible than others to severe bouts of disease. And experiments in animals and human cells have demonstrated how excess fat can disrupt the immune system.

The fastest vaccine ever developed was four years. With billions of dollars invested so far fast tracking the development of the vaccine, it has allowed the vaccine makers produce doses, before knowing of the vaccine works. The idea is that if a vaccine is shown to be protective, use of it can start immediately.
Seventy-six wealthy nations are now committed to joining a global COVID-19 vaccine allocation plan co-led by the World Health Organization (WHO) that aims to help buy and fairly distribute the shots, the project’s co-lead said on Wednesday.
Losing the ability to smell or taste are two of the symptoms associated with Covid-19. But while many have regained their senses, for others it has turned into a phenomenon called parosmia, leaving them trapped in a world of distorted scents.
As the coronavirus pandemic rolls on, an unknown number of seemingly recovered patients are experiencing what is being called post-Covid syndrome — weeks or months of profound fatigue, fevers, problems with concentration and memory, dizzy spells, hair loss, and many other troubling symptoms.
Scientists are studying a phenomenon called "disease tolerance." Understanding it in humans, if it exists, could revolutionize medicine. According to various estimates between 20 and 45 percent of people who get Covid-19, and possibly more - sail through the infection without realizing they had it.
Is it safe to fly with the coronavirus still circulating? That depends partly on where you are. But while hard evidence is scarce, it appears the risk of being infected with covid-19 during a flight is relatively low.
Researchers have found the viral load in infected children to be very high, especially in the first 2 days of infection. We know that transmissibility or risk of contagion is greater with a high viral load.
State officials and federal agencies warn there's a new phone scam circulating: Callers posing as COVID-19 contact tracers are trying to pry credit card or bank account information from unsuspecting victims.
Singing does not produce substantially more respiratory particles than speaking at a similar volume, a study suggests.
