ICMR's 2nd sero survey results
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
- Urban slum and urban non-slum areas had higher SARS-CoV-2 infection prevalence than that of the rural areas in the country.
- Of 29,082 people surveyed from August 17 to September 22, 6.6 per cent showed evidence of past exposure to Covid-19.
- Lower infection to case ratio in August compared to May reflects substantial increase in testing, detection.
- 7.1 per cent of the adult population showed evidence of past exposure to Covid-19.
- In the light of the upcoming festivities, winter season and mass gathering, inventive containment strategies need to be implemented by the states.
- The survey was conducted in the same 700 villages/wards (in urban) from 70 districts from 21 states covered during the first survey.
- 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.
