ICMR asks states to do sero-survey in high-risk populations

May 30, 2020 22:47 IST

The ICMR has advised states to conduct sero-survey to assess the proportion of population including asymptomatic individuals exposed to coronavirus infection. A sero-survey involves testing of blood serum of a group of individuals for the presence of antibodies against that infection to know who has been infected in the past and has now recovered. The apex health body said depending upon the level of sero-prevalence of infection, appropriate public health interventions can be planned and implemented for prevention and control of the disease.
