CDC Releases Guidance on Airborne Coronavirus Transmission
The Centers for Disease Control and Prevention (CDC) released its long-awaited guidance on the aerosolization of the coronavirus. The newly released guidance confirmed that the virus is airborne, and it emphasized that indoor, poorly ventilated areas are particularly conducive to transmission of the virus.
However, the new guidance was not as straightforward as the guidance initially released by the CDC, where the agency referred to the virus as being “an airborne virus.” Within days of posting the guidance confirming the transmission of the coronavirus via aerosolization, the CDC abruptly withdrew the guidance. The agency noted that the posted guidance was a draft version that had mistakenly been posted.
Instead, the new guidance states that the virus can “sometimes be spread by airborne transmission.” The CDC also notes that airborne transmission was not the primary mode of transmission, but that the virus was “spread mainly through close contact from person to person, including between people who are physically near each other (within about 6 feet).”
One point that both the withdrawn guidance and the newly released guidance stressed was that being in a poorly ventilated, indoor area increased the risk of infection.
