The initial results of a Sero survey being conducted in Mumbai by the Brihanmumbai Municipal Corporation were released on July 29, following the first round of the Sero survey. It was revealed that in three municipal wards where nearly 7,000 people were tested for anti-bodies against the SARS-CoV2 virus, 57 percent of those living in slums and 16 percent of those in non-slum areas had anti-bodies against COVID-19. The initial results suggest that these people had been exposed to the virus in the past and had recovered without even knowing about it.
On average, the number of those who had anti-bodies stood at 40.5 percent, which is quite high when compared to Delhi that reported 23.6 percent Sero prevalence, and Ahmedabad that reported about 17.6 percent.
However, we need to consider that just 7000 people were tested in the initial survey and that too from just three municipal wards. To get a better understanding of the initial results, CNBC-TV18's Archana Shukla spoke to Dr Ulhas Kolthur, Biologist at TIFR who is one of the lead investigators of Mumbai Sero survey.Watch the video for more.
