COVID: seroprevalence 10x higher than Covid cases; prison transmission
recent evidence suggests that the seroprevalence of SARS-CoV-2 is >10 times higher than reported (see the CDC summary at https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/commercial-lab-surveys.html , and the article preprint at https://www.medrxiv.org/content/10.1101/2020.06.25.20140384v1.full.pdf Details: --the CDC partnered with 2 commercial labs to assess SARS-CoV-2 antibodies from 6 areas: Connecticut, South Florida, New YorkCity metro area, Missouri, Utah, and Western Washington State. they will expand to 4 other states as well: California, Louisiana, Minnesota, and Pennsylvania --they tested 11,933 blood samples collected for other reasons (sick or routine visits unrelated to Covid-19, such as lipid screening) --goal:1,800 samples from each area, approximately every 3-4 weeks --they balanced the sampling by age (0-18yo, 19-49, 50-64, >65) and sex --this was compared to the positivity rate of PCR of SARS-CoV-2 in those areas --sera were tested at...
