Curious: where does the "6 feet" distancing rule come from? What are the background papers - I'd love to read them.

A lot of people are responding with folk theories. I'm wondering what the solid evidence is for the 6 feet number. How does changing to 5 feet change transmissibility? 4 feet? 10 feet? Is the virus really 0% not transmissible at 6? Other factors (height, etc)?

The conclusion is worth reading in full. At the least it seems that (a) this question is still somewhat open; and (b) I hope people are looking into it.pic.twitter.com/EyCvbaa1JP
