The Importance of Sampling: Estimating the Fraction of the Population Who Have Experienced Prior COVID-19 Infection

In this Grand Rounds, faculty from the Sampling Knowledge Hub and Department of Epidemiology & Biostatistics discussed recent studies of antibody seroprevalence, why sampling matters and best practices moving forward.
