HVAC is not the problem.

The problem is that prisoners routinely share common spaces. It doesn't matter how the air circulates, when they all cook, eat, work, shower, and exercise in the exact same communal rooms.

Combine that with insufficient sanitation, and it's a miracle that only half of them got sick.

HVAC might be a problem, there was a CDC article demonstrating how A/C was attributed to specific cases in China https://wwwnc.cdc.gov/eid/article/26/7/20-0764_article

I agree that HVAC can cause spread. My point is that prison life does not allow for social distancing, and that the HVAC is irrelevant when everyone is living in essentially the same space.

Cruise ships are pretty similar in that people are eating and recreating in the same areas.
