A sero survey attempts to find out whether a person has developed antibodies against COVID-19. The body produces antibodies, a kind of protein, to fight viruses. These antibodies are produced after an infection has occurred. Their presence suggests in the body that an infection by coronavirus has occurred earlier. These antibodies are likely to prevent infection in future. A sero survey helps researchers find out to what extent Covid-19 has spread in the community. A random sample of the population is tested for antibodies and an estimate made for the entire population.
