Deciphering SARS-CoV-2 Transmission With Serology Surveillance
Article

In many countries, diagnostic testing to detect active SARS-CoV-2 infection has played an important role in the management of COVID-19. In this article, we explore how seroprevalence studies, also known as serosurveys, provide a means of understanding community transmission of SARS-CoV-2. We also discuss the challenges of interpreting serological results and identifying people who had mild infections.
