Main Question or Discussion Point

To reduce the transmission of coronavirus, people are recommended to stay 6 feet apart from others. The 6 feet number is a simple guideline, but there is not much difference between 5.9 and 6.0 feet.

How does the number of droplets you breathe from another person vary with the distance d? Is it 1/d, 1/d^2, or something else?

A group of several hundred scientists just published an open letter, "It's time to talk about airborne transmission of covid-19". They criticize out of touch health authorities and summarize the body of knowledge about airborne transmission. I think it's a good starting point for answering your questions.
