One in 15 individuals aged more than 10 years were estimated to be exposed to the Covid-19 by August 2020, according to ICMR’s second national sero survey report released on 29 September 2020. The survey showed that a considerable population is still vulnerable and susceptible to the coronavirus infection.
 

Key findings of the sero survey
  1. Urban slum and urban non-slum areas had higher SARS-CoV-2 infection prevalence than that of the rural areas in the country.
  2. Of 29,082 people surveyed from August 17 to September 22, 6.6 per cent showed evidence of past exposure to Covid-19.
  3. Lower infection to case ratio in August compared to May reflects substantial increase in testing, detection.
  4. 7.1 per cent of the adult population showed evidence of past exposure to Covid-19.
  5. In the light of the upcoming festivities, winter season and mass gathering, inventive containment strategies need to be implemented by the states.
  6. The survey was conducted in the same 700 villages/wards (in urban) from 70 districts from 21 states covered during the first survey.
  7. Since a large proportion of the population is yet susceptible - prevention fatigue to be avoided and 5T strategy (Test, track, trace, treat, technology) to be followed.
