I still have to disagree with you. There are a lot of very dense housing in Manhattan, Bronx, Brooklyn and Queens; as such, there would be a lot of close contact between people even before getting on public transportation. It’s a wonder how Hong Kong with its even denser housing per square mile managed to avoid a major medical disaster.
In Hong Kong they learned social distancing from SARS which was tougher to get, but it would kill you.
They don’t need to be taught twice.
Study your geology.
Manhattan is where the city is densest, because you don’t have to build platforms for the skyscrapers. You got rock.
Or remember Archie Bunker and all the little three-story private homes they showed at the beginning. That is Queens. A few tallish buildings in the center of the borough.
Come here sometime when this is over. You’ll find out why people leave with their eyes as big as saucers.
