I heard a crazy theory from some foreign tourists visiting Vegas many years ago.
The story I heard is that Vegas hotels/casinos mix in small amount of certain gas/chemical in the circulating air that makes people not want to sleep, which makes people gamble more and spend more money.
Some crazy theories people have...
So I can see (as a non-expert) that the well ventilated casinos is the reason for low infection rate in Vegas.
NYC on the other hand has had the extremely highly infection rate because EVERYONE has to take subway and pretty sure there's not much air circulation in the subway cars...
Either way, I think not spending too much time indoors is the key to avoid covid-19. Unfortunately most all indoor space has recirculated, air-conditioned, stale air.
Edit:
I personally think businesses that can leave windows open for fresh air will have lower chance of spreading Covid-19 than ones with barely functioning AC system with little air circulation.
