The Centers for Disease Control and Prevention revised their coronavirus guide on Monday, recognizing that it can sometimes spread through airborne particles that can “stay in the air for minutes to hours”
“These transmissions took place within enclosed spaces that had inadequate ventilation,” says the new CDC guidance. “Sometimes the infected person breathed heavily, for example while singing or exercising.”
The agency added that it is “much more common” for the virus to spread through close contact than through airborne transmission.
The updated guide comes after the agency mistakenly published a review last month that the virus could be spread through aerosols, small droplets that can remain in the air. The guide was quickly removed from the CDC’s website because it was only “a draft of the proposed changes,” the agency said.
