New mass screening finds just over 27% of New Yorkers test positive for Covid antibodies.
New York Times article
General pattern is for people from poorer areas to be more likely to have been infected.
In one small district, over 50% of those tested were positive. The district is called . . . Corona.
ETA: an NYC study some weeks previously found a 19-20% rate iirc but was conducted with people visiting grocery stores, not really a random sampling.
I cant read the NYT article. Was this one from random sampling either?
A lot of the data is here if you scroll down a bit past the non-antibody tests.
Some of the detail might matter. Seeing the numbers over time certainly helps, as well as by age.
Its hard to make comparisons with places like London because there hasnt been mass testing there. We are reliant on small scale random sampling, including from people donating blood, to come up with regional estimates for antibody prevalence.
We also dont know about test accuracy in New York compared to the forms of testing used here. And there are big questions about some other forms of immunity that are way more difficult to test for and so havent been the focus of any population antibody studies at scale so far.
The following is from the most recent report at National COVID-19 surveillance reports
