SARS-CoV-2 Seroprevalence

SARS-CoV-2 seroprevalence is the proportion of a defined population with detectable antibodies against SARS-CoV-2. It is estimated through antibody testing, and estimates can vary with population sampling, inclusion of asymptomatic infections, test-result definitions, and the cost of large-scale specimen collection.
