[Pre-print, not peer-reviewed] Follow-up of 11,468 adults with mild or asymptomatic COVID-19 infection found that serological evidence of previous infection, specifically the presence of either IgG or IgM antibodies, waned quickly over time, with roughly 50% of people undergoing sero-reversion within 30 days of their initial positive test. The rate of sero-reversion was not associated with age, sex, race/ethnicity, or healthcare worker status.
