What Is Sero Survey?
It involves testing of blood serum of a group of individuals to monitor trends in the prevalence of the novel coronavirus infection in a particular area. It helps to understand the proportion of the population exposed to SAR-CoV-2 infection, including asymptomatic or individuals who do not show any signs of COVID-19.
Why Sero Survey?
Depending on the level of seroprevalence of the infection, appropriate public health interventions can be planned and implemented for the prevention and control of the disease.
