serosurvey
Population immunity snapshot
A serosurvey is a study that tests blood samples from a population to measure the presence of antibodies, typically to assess how widely an infection has spread.
Public health officials use serosurveys to estimate true infection rates, which often exceed confirmed case counts: The COVID serosurvey suggested a third of the city had already been exposed.
