CHENNAI: The doubling time of Covid-19 cases in the city has increased to around 47 days, said Greater Chennai Corporation commissioner G Prakash on Saturday.
This was at a time when the national average of doubling time was 21 days, Prakash said.
"ICMR and WHO say that anything above 14 days is a good trend. This means we are doing really well," he said.
