With instances of people contracting COVID-19 even after getting both vaccine doses and a bigger portion of daily cases still coming from high-rises, people have several questions about the ongoing pandemic. And, the BMC thinks the answers may come from sero-surveys. The most prominent question is if and when the third wave is coming.

While the BMC, on Monday, told the Bombay High Court that it does not apprehend a third wave in the city as the vaccination drive is going smoothly, civic officials are sceptical to announce the same in public.
