The following statement now appears on the website: “A draft version of proposed changes to these recommendations was posted in error to the agency’s official website. CDC is currently updating its recommendations regarding airborne transmission of SARS-CoV-2 (the virus that causes COVID-19). Once this process has been completed, the update language will be posted.”
On Friday, the agency updated its website to say that there is “growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others, and travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes).”
Infections can happen when the particles are “inhaled into the nose, mouth, airways, and lungs,” it said. “This is thought to be the main way the virus spreads.”
Now the page has been reversed to the previous guidance, which says that the “virus is thought to spread mainly from person-to-person” and does not mention the possibility of it being airborne.
The World Health Organization, which acknowledged increasing evidence about airborne transmission of the coronavirus in July, said on Monday that it had not changed its stance that the virus is primarily spread by large droplets that are emitted through coughs and sneezes and quickly fall to the ground after being discharged.
“Certainly we haven’t seen any new evidence and our position on this remains the same,” Mike Ryan, executive director of WHO’s health emergencies program, said at a press conference.
