Did things like the number and use of elevators and subway system in NYC help exacerbate the spread and virus numbers coming out of there? Population density leads to things like a lot of common use areas. Also wonder if NY having a lot of people in a cooler climate also helped make things worse. Areas of population density in California didn't get as hard as NYC-yet-is that because of a warmer or even sunnier climate? Might explain why several nursing homes getting hit hard, just like a cruise ship for the most part they're cooped up in the same environment with the same air and common areas.
