@Linda108 Right, it’s just common sense that interfacing with multiple people, passing them in hallways, and living densely crammed together in side-by-side rooms is more likely to cause spread. I don‘t need “proof” to come to that conclusion. Also, the WHO and CDC state that close personal contact is by far the predominant way the virus is being spread, and they specifically point out that hard surface transfer is unlikely. Maybe they don’t have “proof” of this either, but again, it is common sense.
The preference for hotels by some state and city officials is still baffling, though - makes no sense at all. I can’t help but suspect that the powerful hotel lobby is driving these decisions.
