U.S. CDC Revises Guidance, Says COVID-19 Can Spread Through Virus Lingering In Air

U.S. Centers for Disease Control and Prevention (CDC) on Monday said COVID-19 can spread through virus lingering in the air, sometimes for hours, acknowledging concerns widely voiced by public health experts about the airborne transmission of the virus.

Viruses in aerosols can remain in the air for seconds to hours, travel more than two meters, and accumulate in poorly ventilated indoor air, leading to superspreading events, the researchers said.
