Topic:

  • A study of 217 frontline healthcare workers at a German university hospital found 21% suspected they had previously been infected with SARS-CoV-2, but weekly testing for SARS-CoV-2 antibodies identified IgG prevalence 20 days later was 1-2% (assay sensitivity 93.8% and specificity 99%).
