Preliminary test results suggest 21% of NYC residents have Covid antibodies
This study doesn't appear to suffer from the same methodology problems as the Stanford study of a few days ago. In that study, they recruited people through Facebook, and reported an infection rate that was low enough that it could have been caused by false positives.Here, it's closer to a random sample, but more importantly it shows really high rates. Those rates overwhelm any error due to false positives.Also, it shows numbers that are in line with our intuition. It shows higher infections in NYC, and higher infections among blacks. That reflects what the hospitals are seeing.This study may well be really good news.
