A 73% high recovery rate has been reported in Mumbai!
Mumbai witnessed a sudden fall in the number of corona virus cases on Tuesday, which is also the lowest in last 3 months. With 700 new cases, the total number of active cases in the city now has reached 19,990.
Another encouraging news for Mumbaikars is the Serosurvey report which highlights the fact that Mumbai is heading towards 'herd immunity' with a massive recovery rate of 73% and a doubling rate of 69 days. The study also reveals that 57% of the city slum population has developed antibodies already.
Survey Report Details
A Serosurvey report was prepared by the NITI Aayog, Tata Institute of Fundamental Research and BrihanMumbai Municipal Corporation (BMC) which indicates that Mumbai with its 19,990 active cases is heading towards recovery with the development of herd immunity.
By definition, herd immunity means the resistance to the spread of a contagious disease within a population that results if a sufficiently high proportion of individuals are immune to the disease. This immunity could be due to several other previous infections and the presence of antibodies. This further acts as a protective measure for those individuals who are not immune.

Sero-surveillance provides estimates of antibody levels against infectious diseases and is considered the prime standard for measuring population immunity due to past infection or vaccination. The study further showed that seroprevalence was marginally higher in women than in men.

Recording the lowest number of cases in the last 100 days, Mumbai's rise in cases is finally plateauing. With a long doubling rate of 69 days and a high recovery rate of 73%, the ferocity of the deadly virus is under much control now. The BMC has conducted as many as 4.85 lakh tests in the city and the overall growth from July 20 to July 26 has been recorded and limited at 1.03%.
A BMC statement later said, "The results will be valuable to learn more about herd immunity. Although it is still unclear what level of prevalence leads to herd immunity, findings indicate at least in slums this could be attained sooner or later, if the immunity exists and persists in a significant proportion of the population. "The first round of the study was conducted on 6,936 people from three wards - R-North, M-West, and F-North. Higher seroprevalence in slums could be possible due to population density and shared common facilities - toilets, water points, etc. - said the study.
The city of Mumbai, its administration, and people have finally weaved their way onto the road to recovery. As more than half of the city's population develops antibodies, the threat of the much-feared second wave has also been diminished. A low number of cases, increased recovery and immunity and a lower fatality rate are all working in the city's favour to beat the global pandemic.
