Over 86% of Mumbaikars have Covid antibodies: Sero-Survey Report

Mumbai: As per the recent sero survey conducted by the Brihanmumbai Municipal Corporation (BMC), as much as 86.64 per cent of the 8,674 people surveyed have developed antibodies against Covid-19. The survey, fifth since the onset of the coronavirus pandemic, was conducted between August 12 and September 9, 2021, the civic body said in a release.

This is significantly higher than the third sero-surveillance conducted in March this year, which found 36.3 per cent of those surveyed had antibodies against Covid-19.

The presence of antibodies in slums was 87.02 per cent, while it was 86.22 per cent in other areas, it said. “Overall sero-prevalence in slum and non-slum areas in the city of Greater Mumbai is much higher in comparison to the last survey,” the BMC said, adding that there was no significant difference in sero-prevalence of Mumbai ‘island city’ and the suburbs.
