I used to think CDC recommendations were not great but better than nothing. I’ve changed my mind after seeing them say coronavirus can’t survive on surfaces for very long, so I’m retracting this comment.
I had heard the 6 feet rule (which roughly matches my “how far I think people can usually spit”), but didn’t know where I had heard it from, and scaled it up a bit for additional margin of error based on my intuitive knowledge of cough physics.
CDC says 6 feet is safe, but not what that’s based on.
