Evidence shows the virus is primarily spread through droplets that come out of people’s mouths and noses. Large droplets fall onto surfaces rapidly and can be picked up on fingers and carried to the eyes, nose or mouth. That’s why it’s important people don’t touch their faces and wash their hands regularly.
But there is now more evidence that smaller-sized droplets can remain in the air in the form of aerosol particles which can be inhaled. Several international health authorities have already acknowledged this way of transmission, stressing the need to wear masks.
A federal official familiar with the situation told CNN the guidance is “getting revised,” but didn’t say when the update would be posted to the CDC website.
Researchers and doctors said they were glad to see CDC was expected to acknowledge airborne transmission, but some worried the back and forth could cause more confusion about how the virus spreads and what measures will reduce the risk.

A: Yes, that’s a good idea because cell phones are basically “petri dishes in our pockets” when you think about how many surfaces you touch before touching your phone.
“There’s probably quite a lot of microorganisms on there, because you’re holding them against your skin, you are handling them all the time, and also you’re speaking into them,” said Mark Fielder, a professor of medical microbiology at Kingston University.
