Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, told CNN’s Dr. Sanjay Gupta during the CITIZEN by CNN event on Tuesday that you can assume aerosols are a component of Covid-19 transmission. And while the amount they contribute to the spread it isn’t yet known, it doesn’t change what has been said.
“When you look at what’s going on and the evidence that we’ve seen so far, you can assume that a component, and we don’t know, and here’s where you’ve got to be humble enough and honest enough, that we don’t know the extent to which the aerosol component is contributing to transmission,” Fauci said.
“You can make a reasonable assumption, Sanjay, that some aspect of transmission can be and is by aerosol,” he said.
“The interesting thing about that – it doesn’t change anything that we’ve been saying. It means wear your mask. It means avoid close contact. It means avoid crowds. And it means what we’ve been saying, the third or fourth thing that I mentioned to you just a little while ago, is that outdoors is better than indoors,” he said – because if there is aerosol indoors, there can be some recirculation.
Fauci said there have been some case reports of situations in places such as restaurants, “where it looks like it almost had to be an aerosol spread.”
Remember: The US Centers for Disease Control and Prevention abruptly reverted to its previous guidance about how coronavirus is transmitted, after saying on Friday that the virus can spread through the air.
