Sero-prevalence studies

Sero-prevalence studies are research efforts that measure how many people in a population have antibodies against a specific virus, like COVID-19. Antibodies are proteins your immune system produces after infection or vaccination, indicating past exposure. These studies involve testing blood samples from a representative group of people to estimate how widespread the infection has been, including cases that were unnoticed or asymptomatic. Sero-prevalence data helps public health officials understand the true extent of an outbreak, assess immunity levels, and make informed decisions about health measures and vaccination strategies.
