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.
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.
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.
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.
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.
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 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.
Adults with positive SARS-CoV-2 test results were approximately twice as likely to have reported dining at a restaurant than were those with negative SARS-CoV-2 test results.
Whether the virus is airborne isn’t simply a scientific question. If it is, it could mean that in places where the virus has not been properly contained (e.g., the US), the economy needs to be reopened more slowly, under tighter regulations that reinforce current health practices as well as introducing improved ones.
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.
