Just a reminder that this paper provides a cute way to estimate the “true” prevalence of Covid (or indeed any pathogen) in a community: geometric mean of case rate and positivity rate.

Thus for instance based on today’s numbers for the NYC metro area on covidactnow.org
50.4 per 100K = .000504 13.7% positivity rate = 0.137
True prevalence = 0.831%
