The US Centers for Disease Control and prevention on Monday abruptly reverted to its previous guidance about how coronavirus is transmitted, removing language about airborne transmission it had posted just days earlier.

CDC is currently updating its recommendations regarding the airborne transmission of SARS-CoV-2 (the virus that causes COVID-19).

"A draft version of proposed changes to these recommendations was posted in error to the agency's official website. Once this process has been completed, the updated language will be posted," Jason McDonald, a CDC spokesman, said in a response emailed to CNN.

Despite several studies that have shown the novel coronavirus can spread through small particles in the air, the CDC page now says that Covid-19 is thought to spread mainly between people in close contact -- about 6 feet -- and "through respiratory droplets produced when an infected person coughs, sneezes or talks," this is the same language it posted months ago.

In language posted Friday and now removed, CDC said Covid-19 most commonly spread between people who are in close contact with one another and went to say it's known to spread "through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, breaths."

In the Friday update, the CDC had added new measures to protect yourself in others, including recommendations to use air purifiers to reduce airborne germs in indoor spaces and clear guidance to " stay at least 6 feet away from others, whenever possible".

The updated CDC page had also changed the language around asymptomatic transmission, shifting from saying "some people without symptoms may be able to spread the virus" to saying "people who are infected but do not show symptoms can spread the virus to others." That language has now been removed.
