Is serology a feasible way to screen for SARS-CoV-2
infection at a population level?
Serology is useful to determine prior exposure to SARS-CoV-2 within a
given period of time (the length of time following infection that one
remains positive is unknown). Detection of antibodies specific to the
receptor binding domain of the spike protein indicates neutralization
capacity, hence informing better about the development of protective
immunity.33,96
