Peer Review of “COVID-19 Antibody Seroprevalence in Santa Clara County, California”
The high reported positive rate in this serosurvey may be explained by the false positive rate of the test and/or by sample recruitment issues.
A new Stanford preprint was released earlier today (PDF, SI). The authors claim that the true population prevalence of COVID-19 in Santa Clara County is 50–85X higher than the number of confirmed cases. They base their reasoning on a serosurvey of 3330 participants.
