ICMR’s 4th sero survey: Over 67% population has Covid antibodies


New Delhi: The results of the fourth sero survey, conducted across the country, are out. And, they are quite encouraging. As per the results, 67.6 per cent, or roughly two-thirds, of the population above the age of 6 have developed antibodies against coronavirus, the government has said.

The results of the fourth sero survey, conducted by ICMR in June-end and early July, were announced by the government on Monday. The period of study was when the second wave of the pandemic had begun to subside.

Sharp rise from 3rd sero survey

As many as 28,975 persons were tested for antibodies against SARS-CoV2 virus. The sample also covered minors above the age of 6, the first time that they have been studied.

Of these, antibodies were found in 67.6 per cent of the sample. This is a sharp rise from the results of the third sero survey conducted in December 2020 and January 2021. Of those studied, less than 25 per cent had developed the antibodies.

The first sero survey, conducted in May-June last year, had found 0.7 per cent people with the antibodies, while the second one in August-September had 7.1 per cent.

Heartening results

The higher prevalence of antibodies in the populations means the third wave of the Covid-19 pandemic, when it strikes, may not be as severe as the second one. Seen together with the vaccination figures, these results provide further reassurance that, with some caution, we might be able to tide over the crisis without the disasters that the country had witnessed in April-May.

No space for complacency
While the results of the sero survey are encouraging, health experts have warned against any complacency. They have urged people to continue following Covid-appropriate behaviour, for there still is a significant chunk of the population that is vulnerable to the infection.

The Uttar Pradesh cancelled the Kanwar Yatra only after intervention of the Supreme Court. The Apex Court also rapped the Kerala government for easing of Covid-19 restrictions for Bakri Eid.
