There are around 22 districts in Tamil Nadu which have been declared as hotspots. There are 14 such districts in Maharashtra, 11 in Andhra Pradesh, and 12 Rajasthan. Within the 170 red zones, there are 123 districts with large outbreaks and 47 with clusters.
The health ministry has issued detailed guidelines to states for containment in areas where there is an outbreak. Only essential services will be allowed in these areas and entry and exit points will be strictly defined.
Special teams, comprising health workers, municipal corporation staff, and volunteers, will conduct door-to-door surveys to check for Covid-19 symptoms, such as cold, fever and breathlessness. Contact tracing and health surveillance will be an important part of the containment strategy.
