MUMBAI: The BMC has launched its fifth sero survey ahead of a possible third wave. Sero prevalence studies show past exposure to a virus and the spread of infection in the population, said officials.
Sero survey 5 began on Thursday with the help of IDFC Institute and ATE Chandra Foundation in all 24 wards through municipal dispensaries for slums. Clinics of selected general medical practitioners will be roped in around the city. “Around 8,000 random samples will be tested at Sion Hospital,” said a senior civic official.
The first two surveys were done in July and August 2020 in three wards. The third survey was conducted in March 2021 in 24 wards and the fourth survey was conducted from May to June 2021 in the paediatric age group.
