Analysis: Monitoring disease ‘hot spots’ could prevent the next pandemic
A more coordinated effort by scientists, stakeholders and community members will be required to stop the next deadly virus that's already circulating in our midst.
As COVID dissipates in the U.S., cold and flu viruses may return with a vengeance
Some experts point to a series of factors that could make for a rough re-entry to the mixed microbes world of cold and flu viruses.
Can people vaccinated against COVID-19 still spread the coronavirus?
The COVID-19 vaccines are a smash success. But that doesn't mean they keep every vaccinated person completely free of the coronavirus.
Does weather affect the spread of the coronavirus outside?
The World Health Organization says the virus can be transmitted in any kind of weather and that there is no reason to believe that cold weather can kill it.
New guidance from the CDC says that 15 minutes of exposure – regardless of whether that occurs at one time – can result in transmission of the coronavirus.
Studies have shown that people may be contagious for about two days before developing COVID-19 symptoms. Experts say right before developing symptoms is when people are likely the most contagious.
The top U.S. public health agency stirred confusion by posting — and then taking down — an apparent change in its position on how easily the coronavirus can spread from person to person through the air.
COVID-19 is mainly transmitted through respiratory droplets in the air. Why isn't improving ventilation a key part of the effort to reopen schools?…
The World Health Organization is acknowledging the possibility that COVID-19 might be spread in the air under certain conditions. This comes after an open letter from more than 200 scientists published this week urging the agency to do so.
