CDC updates guidelines (again) to note risk of airborne transmission

ATLANTA GEORGIA: The Centers for Disease Control and Prevention has updated its website to warn that the coronavirus can spread through the air, something public health experts have been warning about for months but went unacknowledged by the agency until Monday.

The CDC says people can be exposed to the virus in small droplets and particles that can linger in the air for minutes to hours, potentially infecting people who are farther than 6 feet away and even people who come into the area after an infected person has left.

“There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away,” the CDC says on its website.

The CDC's previous guidance said the virus spreads primarily among people who are in close contact with one another – within about 6 feet – through respiratory droplets produced when an infected person coughs, sneezes or talks. The current guidance says that's still the greatest risk.
