One of the most pressing questions about the COVID epidemic is why some places are doing so much better than others. This applies both globally and within the United States. One example that gets raised a lot is why is New York State doing so relatively well while states in the South and Southwest are being hit so hard?
We need to start the conversation saying a) We don’t completely know and B) There are clearly multiple factors. But let me share some thoughts with you on one part of this debate.
While I still cringe that I see people in New York City not wearing masks, the truth is mask wearing is near universal in New York City. My sense is that aggressive mitigation efforts, both pressed by state authorities and embraced by the population, is the main reason why New York has at least to date avoided a second wave of infection. The last time New York’s case positivity rate went over 2% was June 2nd.
