Using this interactive map you can see the risk level of attending an event, given the event size and location. You can reduce the risk that one case becomes many by wearing a mask, distancing, and gathering outdoors in smaller groups.
Scientists have found that a specific mutation, known as 614G, which was first spotted in China in early January and then spread quickly throughout Europe and NY city, made the pandemic harder to stop.
A new study on Duke University’s coronavirus testing and surveillance strategy highlights the importance of widespread testing of asymptomatic individuals to prevent transmission and provides support for the feasibility of a pooled testing approach, in which multiple samples are combined in a single test.
The drug maker Pfizer said on Wednesday that its coronavirus vaccine had no serious side effects, the first step of complete results from a late stage vaccine trial. The data showed that the vaccine prevented mild and servere forms of COVID-19
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.
Epidemiologists reviewed 25 studies of cloth face masks. Here’s what they found out about how well they work, why they work, who they protect and why the mosquito and chain-link fence analogy is wrong.
The virus responsible for Covid-19 can survive for up to 28 days on surfaces such as glass, steel, vinyl, paper and polymer banknotes, Australian researchers said on Monday, reinforcing the importance of effective cleaning and handwashing to curb the spread of the disease.
This post answers some important question about long haulers. In essence some people experience symptoms like fatigue, shortness of breath, joint pain, chest pain, cough. These symptoms are not related to the severity of the infection.
South Korea's response to Covid-19 has been widely praised. The reason for their success is contact tracing. They have been able to quickly identify people exposed to the virus and the citizens comply with a 2 week quarantine to stop the spread.
It’s still a way off, but a feasible, fast, at-home SARS-CoV-2 test is on the horizon. This new device being developed by Caltech will be able to detect coronavirus in ten minutes by analyzing a drop of your blood.
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.
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.
Looking at the records of over 73 million patients in the US, of whom 12,033 had Covid-19, the study found those who had recently been diagnosed with a substance use disorder were significantly more at risk of Covid-19 than the average population.
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. But it all depends on how loud a person is, according to the initial findings which are yet to be peer reviewed. The project, called Perform, looked at the amount of aerosols and droplets generated by performers.
Scientists who have been monitoring immune responses to the virus are now starting to see encouraging signs of strong, lasting immunity, even in people who developed only mild symptoms of Covid-19, a flurry of new studies suggests.
The global global misinformation dubbed infodemic – an oversupply of information, carrying with it fake news, rumours, and conspiracy theories has put people in harm's way. Bad ideas and poor advice, shared amongst friends, family, and total strangers alike.
Across the United States, at least 200,000 more people have died than usual since March, according to a New York Times analysis of estimates from the Centers for Disease Control and Prevention. This is about 60,000 higher than the number of deaths that have been directly linked to the coronavirus.
A growing number of nations and companies are either trialling or rolling out systems that monitor sewage, and they may provide the key to ensuring that future Covid-19 outbreaks are kept under control.
Inspired by a unique kind of infection-fighting antibody found in llamas, alpacas, and other camelids, a research team at the University of California, San Francisco, has synthesized a molecule that they say is among the most potent anti-coronavirus compounds tested in a lab to date
New research has found that people with a SARS-CoV-2 infection who are asymptomatic carry just as much virus in their throats, lungs, and noses as those who have symptoms. Some experts believe that asymptomatic people have caused the virus to spread more readily in communities.
Scientists at La Jolla Institute for Immunology in California showed that infection with common cold coronaviruses can generate an immune response that resembles key pieces of the immune response generated by SARS-CoV-2 – the virus that causes COVID-19. This raises the possibility that previous infection with one of the milder coronaviruses could make COVID-19 less severe.
The vaccines will be put into the general population for the first time in phase 3, after previous trials have focused on safety, immunogenicity and immune response in a small number of humans, said the WHO official. The phase-3 trial will test whether the vaccines can "protect large numbers of people over a prolonged period of time."
The most compelling argument against human challenge trials for a COVID-19 vaccine, though, is that it might not actually be any faster. In order to infect people with the virus, we have to have a tested viral dose — one that is strong enough to infect people, but not so strong it gives an infection worse than natural spread — which can take up to a year to develop, according to Weijer.
The 5 myths answered are, will my oxygen level drop, wearing a mask? Do I need a mask, If I am not unwell? A mask won't stop a wearer getting ill. You don't have to wear a mask if you have a medical condition and its enough to just wear a mask.
A new report in the Journal of the American Planning Association concludes that density doesn’t make a city sick; crowding and connectivity do. It’s important to disentangle those concepts.
For a world crippled by the coronavirus, salvation hinges on a vaccine. But in the United States, where at least 4.6 million people have been infected and nearly 155,000 have died, the promise of that vaccine is hampered by a vexing epidemic that long preceded Covid-19: obesity.
The more we learn about kids and the coronavirus, the riskier reopening schools for in-person learning appears to be, at least in areas with high caseloads. There have already been many reports about the virus spreading through schools and summer camps, and evidence has begun to support the notion that children can play a key role in community transmission.
While the world is transfixed by the high-stakes race to develop a COVID-19 vaccine, an equally crucial competition is heating up to produce targeted antibodies that could provide an instant immunity boost against the virus.
The coronavirus that causes COVID-19 has sickened more than 16.5 million people across six continents. It is raging in countries that never contained the virus. It is resurging in many of the ones that did. If there was ever a time when this coronavirus could be contained, it has probably passed. One outcome is now looking almost certain: This virus is never going away.
Research already shows that germicidal UV can effectively inactivate airborne microbes that transmit measles, tuberculosis and SARS-CoV-1, a close relative of the novel coronavirus. Now, with concern mounting that the coronavirus that causes COVID-19 may be easily transmitted through microscopic floating particles known as aerosols, some researchers and physicians hope the technology can be recruited yet again to help disinfect high-risk indoor settings.
One of the first school districts in the country to reopen its doors during the coronavirus pandemic did not even make it a day before being forced to grapple with the issue facing every system actively trying to get students into classrooms: What happens when someone comes to school infected?
I am in favor of adopting Japan's strategy, which has proven most effective in the fight against super-spreaders. The Japanese didn't impose a strict lockdown during the first wave, but they were roughly as successful as we were. That is exactly what we need for the second wave. The virologist Christian Drosten (one of Germany’s leading figures in the COVID-19 crisis) also sees this strategy as the correct course of action.
Two new studies, though from different parts of the world, have arrived at the same conclusion: that young children not only transmit SARS-CoV-2 efficiently, but may be major drivers of the pandemic as well.
“Every health system, every public health department, every jurisdiction really has their own ways of going about things,” says Caitlin Rivers, a senior scholar at the Johns Hopkins Center for Health Security. “It's very difficult to get an accurate and timely and geographically resolved picture of what's happening in the US, because there's such a jumble of data.”
While there is no universally agreed definition of a superspreading event, it is sometimes taken to be an incident in which someone passes on the virus to six or more other people. Getting to the bottom of why these puzzling clusters occur could be key to gaining control of the covid-19 pandemic and stopping a second wave of cases.
Between pop-up testing sites, doctors offices, worksite testing and self-administered tests, most patients don't know what type of coronavirus test they're taking -- or how accurate it may or may not be, explained Dr. Shira Doron.
A study from China found 16% of household contacts developed COVID-19, and that spouses of the index case (meaning the first person to spread it in that cluster) were more likely to get infected than other family members.
Of the 100 COVID-19 patients, 78 had structural changes to their hearts. Within that group, 76 had a biomarker that is typically found in patients who had a heart attack, and 60 had heart inflammation, called myocarditis. The patients were all “mostly healthy … prior to their illness,” the researchers said.
Center for Disease Control Director Robert Redfield testified in a Buck Institute webinar that suicides and drug overdoses have surpassed the death rate for COVID-19. Redfield argued that lockdowns and lack of public schooling constituted a disproportionally negative impact on young peoples’ mental health.
In a video posted Monday online, a group of people calling themselves “America’s Frontline Doctors” and wearing white medical coats spoke against the backdrop of the Supreme Court in Washington, sharing misleading claims about the virus, including that hydroxychloroquine was an effective coronavirus treatment and that masks did not slow the spread of the virus.
While the world awaits the results of large clinical trials of Covid-19 vaccines, experts say the data so far suggest one important possibility: The vaccines may carry a bit of a kick. In vaccine parlance, they appear to be “reactogenic,” meaning they have induced short-term discomfort in a percentage of the people who have received them in clinical trials.
Child care just isn’t as available as it was before the pandemic. Data provided to FiveThirtyEight by the job-search website Indeed shows that child-care services have been much slower to hire again (a useful proxy for re-opening) than other areas of the economy:
In May, the Centers for Disease Control and Prevention updated its guidelines to clarify that while COVID-19 spreads easily among speakers and sneezers in close encounters, touching a surface “isn’t thought to be the main way the virus spreads.”
The first large study of the safety and effectiveness of a coronavirus vaccine in the United States began on Monday morning, according to the National Institutes of Health and the biotech company Moderna, which collaborated to develop the vaccine.
Dr. Sapan Desai, who supplied the data for two prominent and later retracted studies, reported that anti-malaria drugs like hydroxychloroquine, which President Trump promoted, were linked to increased deaths of Covid-19 patients. The now-tainted studies helped sow confusion and erode public confidence in scientific guidance when the nation was already deeply divided over how to respond to the pandemic.
2020 will be a year of reckoning for the world’s food systems. In just months, COVID-19 shut down half the globe. Images of panic buying, empty grocery shelves and miles-long queues at food banks have suddenly reminded us how important food systems are in our lives and how imbalanced they have become.
Even though the US Centers for Disease Control and Prevention cannot start ranking leading causes of deaths until the end of the year -- in order to get a full year's worth of data -- statisticians at the agency told CNN they expect Covid-19 will end up among the Top 10 leading causes of death in the nation.
This post talks about various testing methods for checking the effectiveness of your homemade face masks. The purpose of these masks is to reduce the distance your breath travels to infect others.
Not every mask is equal. As countries around the world grapple with varying levels of mask shortages, one of the most effective types of face masks for blocking airborne coronavirus particles has been reinvented – with a brilliant experimental tweak that could enable us to make more masks with less material, and maybe save more lives as a result.
On Tuesday, the National Academy of Medicine, tasked by top U.S. health officials, named an expert panel to develop a framework to determine who should be vaccinated first, when available doses are expected to be scarce. But that panel is ostensibly encroaching on the role of the Advisory Committee on Immunization Practices, a panel that has made recommendations on vaccination policy to the Centers for Disease Control and Prevention for decades, including drawing up the vaccination priority list during the 2009 H1N1 flu pandemic.
In addition to impairing the immune and vascular systems and triggering cerebrovascular and neurological dysfunction, smoking and vaping often worsen the outcomes for patients who contract influenza or other respiratory or pulmonary diseases.
Sweden’s top health authority says people who have had the novel coronavirus are likely to be immune for at least six months after being infected, whether they’ve developed antibodies or not.
The number of people infected with the coronavirus in different parts of the United States was anywhere from two to 13 times higher than the reported rates for those regions. The findings suggest that large numbers of people who did not have symptoms or did not seek medical care may have kept the virus circulating in their communities.
In a recent interview with Harvard professor Tsedal Neeley, Merck CEO Ken Frazier warned that these predicted timelines are doing “a grave disservice to the public.” For one thing, he said, vaccine development takes time. The fastest vaccine ever developed before now was the mumps vaccine, which took four years.
A University of Oxford group and the British-Swedish pharmaceutical company AstraZeneca reported Monday that their coronavirus vaccine candidate, on which the U.S. and European governments have placed substantial bets, was shown in early-stage human trials to be safe and to stimulate a strong immune response.
Evidence has shown masks likely do reduce the spread of COVID-19, so wearing them is a good thing – particularly as Victoria continues to grapple with a second wave. But one conversation we’re not having enough is around how to safely dispose of single-use masks. Disposing of used masks or gloves incorrectly could risk spreading the infection they’re designed to protect against.
A new STAT analysis of testing data for all 50 states and the District of Columbia, however, shows with simple-to-understand numbers why Trump’s claim is wrong. In only seven states was the rise in reported cases from mid-May to mid-July driven primarily by increased testing. In the other 26 states — among the 33 that saw cases increase during that period — the case count rose because there was actually more disease.
In the midst of a global crisis, scientists are trying to solve an epistemologically intractable question. Defining whether a drug “works” has never been easy, a task vexed by methodological uncertainty, commercial pressures, statistical errors, or sometimes straight-out bad practices. Facing a new disease, researchers have to rethink what success even means. Is it lower mortality? Less disability upon recovery? Faster recovery? The answers are cryptic because the questions are just educated guesses.
Experts say testing is a vital component to controlling the outbreak, but one test result still isn’t a green light to visit vulnerable friends or family members. The nature of covid-19, the time it takes for someone to develop symptoms and the varied ways the virus affects people make each test a snapshot in time more than a definitive answer.
In short, though antibodies have proved invaluable for tracking the spread of the pandemic, they might not have the leading role in immunity that we once thought. If we are going to acquire long-term protection, it looks increasingly like it might have to come from somewhere else.
In the heated debate over reopening schools, one burning question has been whether and how efficiently children can spread the virus to others. A study of 65000 from South Korea offers an answer: Children younger than 10 transmit to others much less often than adults do, but the risk is not zero. And those between the ages of 10 and 19 can spread the virus at least as well as adults do.
The real unknown is what Covid-19 does around other viruses. Every autumn there is a predictable series of outbreaks of respiratory viruses. It starts with rhinovirus, the main cause of the common cold, which breaks out every September as young children go to school and swap mucus. As no parent needs to be told, children are to sniffles what mosquitoes are to malaria.
Below is an updated list of 19 of the most-talked-about treatments for the coronavirus. While some are accumulating evidence that they’re effective, most are still at early stages of research. We also included a warning about a few that are just bunk.
Though hand sanitizer is commonly recommended to help keep your hands clean while in public—or even inside your home—so many of them have been discovered to have methanol, which can be toxic if either ingested or infiltrated wrongly through skin.
