Similar to the first one, the second survey was also conducted in over 29,000 individuals in 700 villages and wards in 70 districts of 21 states. The survey was conducted between August 17 and September 22. With prevalence of the infection rising since May, the government strongly emphasised that a large part of the population was still susceptible and urged people to adopt Covid-appropriate behaviour like maintaining safe physical distance, wearing masks and following hand hygiene.
Bhargava shared data from other countries to show that India’s infection prevalence was on a par with countries such as the US with 9.3%, while Brazil has 2.8% and Spain 4.6%.
Sero surveys in cities showed Delhi having 23.5% and 29.1% prevalence in the first two surveys. Mumbai had a prevalence of 57.8% in slums and 17.4% in non-slums, Chennai 21.5%, Ahmedabad 17.6%, Puducherry 22.7% and Indore 7.8% prevalence.
