Mumbai’s sero-survey: According to the findings of Mumbai’s second sero-survey, people in the 41-60 age group were most exposed to the coronavirus in both slums and non-slum areas. The findings show that of the 1,060 people aged 41-60 years surveyed in slums, 50.3 per cent showed the presence of antibodies against Covid-19, and of 964 people in same age bracket surveyed in non-slums, 18.6 per cent tested positive. The primary reason for the high prevalence of antibodies in this age bracket is believed to be the fact that this is a working group and therefore likely to be more exposed to the virus. Compared to this age group, those aged above 60 are least exposed and most protected. Just 13.2 per cent of those belonging to this age group in non-slum areas showed prevalence of antibodies. In contrast, 48.2 per cent of those aged above 60 surveyed in slums had antibodies.
