Maharashtra Covid-19 task force member Dr Shashank Joshi on Monday said it is necessary to conduct a state-specific sero survey to assess the presence of anti-bodies among people as the state is still reporting a high number of coronavirus cases.

He said Maharashtra, which has reported 63,57,833 coronavirus cases as on August 9, is faced with a "thick tail" of Covid-19 though the second wave of the pandemic has ebbed but has not gone away completely. The task force member said the Maharashtra government has given a big relaxation by allowing fully vaccinated people to travel in suburban trains in Mumbai from August 15 and if the cases continue to drop, more easing of curbs may take place from September 1.
