‘The national serosurvey by ICMR was designed to capture the extent of the spread of Covid infection at the national level. Therefore, the national serosurvey results do not reflect the heterogeneity of seroprevalence between districts and even between states,’ a statement issued by the Union Ministry of Health and Family Welfare said. The Union ministry also urged all states and union territories to conduct seroprevalence studies of their own in consultation with the ICMR.
