Tamil Nadu with 22 districts has the highest number of designated hotspots in the list. This is followed by Maharashtra, Rajasthan and Andhra Pradesh with 11 districts each.

Of the 170 hotspots, 47 of them have cluster outbreaks but do not have community transmission, the government said.

Besides this, 207 districts where the rate of doubling of cases is currently low but they can be potential hotspots have been classified as “non-hotspots” or “white zones”.

States have been asked to ensure that the outbreak is contained in all the hotspots. If no new outbreaks are reported within 28 days and all the existing patients recover, the area can be declared a green zone, the government added.
