Population density plus the fact that in New York a lot more people take crowded public transportation, and in L.A., most people drive their own cars.

The subway in New York is a hyper-efficient disease vector besides being the most filthy public transportation I’ve seen anywhere in the world, both the stations and the trains.

All these crowded transportation venues spread the virus like no other city and its environs.
