I’ve asked myself this question. I have no hard data to back this up, but wonder If it’s related to outside time and vitamin D absorption, which seems to have an affect on covid. Ex: did NYC have a tougher time than Florida as a result of this, and even with all the protocols in NYC, they could do only as well as Florida with no rules.

NYC has a combined sewer system [0] [1] that overflows when it rains more than .... ~1/10 of an inch per hour (iirc). The fecal-> aerosol transmission route is certainly very important: https://news.ycombinator.com/item?id=27156256

"Who do you share a bathroom with" is very important for tracking transmission. In NYC, everyone shares a bathroom.
