Global COVID-19 infection rates may be higher than previously reported

Serosurveillance provides estimates of antibody levels against infectious diseases and is considered the gold standard for measuring population immunity due to past infection or vaccination. A study publishing November 10 in the open access journal PLOS Medicine, jointly authored by the World Health Organization’s (WHO) Unity Studies and SeroTracker and colleagues, suggests that based on seroprevalence, global COVID-19 infection rates are likely to be higher than previously reported.
