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.<p>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.<p>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.<p>This study may well be really good news.
