Sero Survey In Mumbai: 57% Antibodies In Slum Area And 16% In Other Areas

In the country’s financial capital Mumbai, the outbreak of corona is decreasing. For the first time in three months, only seven hundred new corona patients appeared in a day. Meanwhile, a sero-surveillance study was conducted in Mumbai, which revealed that 57 percent of the slum area and 16 percent of the non-slum area had developed antibodies, that is, many people were affected by corona.

The Siro Surveillance Survey in Mumbai was started on 3 June. During this period, 6936 samples out of an estimated 8870 were collected. The survey was carried out by mid-July in three areas of R-North, M-West and F-North of slum area and non-slum area. This survey revealed that more corona patients are asymptomatic.

The Brihanmumbai Municipal Corporation (BMC) said that this survey result will prove to be very effective in gathering more information about herd immunity. There is a plan to conduct another survey by BMC, which aims to study the spread of infection and about herd immunity.

The serological survey for SARS-CoV2 infection was jointly conducted by NITI Aayog, BMC and Tata Institute of Fundamental Research (TIFR). Serological survey tests the blood serum of individuals to check the prevalence of antibodies against infection.

BMC claimed that the spread of corona in the slum area could possibly be due to population density. All the people in the slum area use facilities like public toilets and water. However, BMC is yet to reach any specific conclusion regarding herd immunity.

The BMC states that the sero-surveillance survey also indicates that the infection rate (IFR) is likely to be very low in the range of 0.05–0.10 percent. BMC believes that due to social distancing and hygiene in non-slum areas, Corona could not get much footfall.

It is worth noting that till July 28, more than 1 lakh 10 thousand corona cases have been reported in Mumbai, in which 6184 people have died.
