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.

There was a marginal difference gender-wise. Among women there was 88.29 per cent sero-prevalence compared to 85.07 per cent in men.

Here are top findings from BMC’s latest sero-survey:
-Age-wise, sero-prevalence varied from 80 per cent to 91 per cent.
-The sero-prevalence in healthcare workers was 87.14 per cent.
-Of total 8,674 samples examined during the survey, 20 per cent were of health workers.
-The survey was conducted by the public health department and three civic hospitals with the support from A.T.E. Chandra Foundation and IDFC Institute.
-It included participants above 18 years from all 24 wards of the city.
-Sero-prevalence among people who were vaccinated was much higher than those who had not been inoculated.
The civic body, however, urged people to continue following the COVID-19 safety protocol as a third wave is anticipated. “Even if antibodies are found, precautions such as use of masks, maintaining hand hygiene and safe distance must be followed,” the BMC appealed.
