This is bullshit:
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.
"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," Jason McDonald, a CDC spokesman, said in a response emailed to CNN.
The guidance had been quietly updated on Friday, according to the CDC's website. CNN was first to report the change on Sunday. The CDC responded to CNN just before noon on Monday to say it was reverting to the previous guidance.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.
