The Indian Council of Medical Research (ICMR) announced Tuesday that it will be conducting a community-based sero-survey to “estimate the prevalence of the SARS-Cov-2” infection in the country.

Sero-surveys involve testing the blood serums of a group of individuals. According to a statement issued by the ICMR, the survey will be conducted in 69 districts across 21 states in collaboration with the health ministry, the National Centre for Disease Control (NCDC), state health departments and other “key stakeholders” like the World Health Organization.

According to an article by The Print, of the total 69 "randomly selected" districts, 16 are from red zone, 31 from orange zone and 22 from green zone.

The list includes three districts from Tamil Nadu: Thiruvannamalai, Chennai and Coimbatore.

“This household survey will cover 24,000 adults distributed equally across four strata of districts categorized on the basis of reported cases of COVID-19,” read the statement.
