Amongst the advisories following the lockdown extension till May 3, the Health Ministry on Tuesday announced that 170 COVID-19 hotspots have been identified in the country on the basis of number of cases and the rate at which they double in that area. 

Preeti Sudan, the health secretary said in a letter that these hotspots have to be updated every week on Monday or earlier.

Based on the number of case reported from each state, the districts have been classified into:

  • Hotspots,
  • Non-hotspots districts reporting cases
  • Districts which have not reported positive cases

Hotspots (Red Zones) are areas with the highest case load districts contributing to more than 80 per cent of cases in lndia, or highest case load districts contributing to more than 80 per cent of cases for each state in lndia or districts with doubling rate of less than 4 days (calculated every Monday for last 7 days, to be determined by the state government).


If no cases are reported from hotspots (designated red zones) in the next 14 days after effective containment activities, they will be designated orange zones and if no case is reported for 28 days, they will become designated green zones.

What is the government going to do?

As the coronavirus brings superpower nations to its knees, India is scrambling to not repeat the mistakes committed by them – by extending lockdown, testing vigorously albeit a bit late as COVID-19 toll here is nearing 12,000.

Earlier in the day, the Joint Secretary in the Ministry of Health, Lav Agarwal, said that the Cabinet secretary held a video conference with all chief secretaries, DGPs, health secretaries, collectors, SPs, municipal commissioners and CMOs and discussed the hotspots and held orientation on the field level implementation of containment strategy.

Quoting Lav Agarwal from PTI, "They were told about large outbreak containment strategies, cluster containment strategies. Delineation of buffer and containment zone, parameter mapping, defining of entry and exit points were also discussed in detail.”

What are Containment zones, Buffer zones?

Containment zone: These are geographical areas from where a large number of cases have been reported and will be identified by the RRT (Rapid Response Teams) who will map the local transmission of the virus in that area. They will demarcate 3 Km area around the epicenter of the virus outbreak, the whole of which will become the containment zone. Movement of public in these areas will be under check to control the spread of the virus.

A buffer zone is the adjoining area of the affected district/rural areas of the COVID affected city.

It is an additional 5 Kms radius (7 Kms in rural areas) of administrative boundary which also includes neighboring districts/per-urban zone, as detailed in the cluster containment plan.

The containment operation, according to the ministry, would be deemed over when there is no case reported in 28 days from an area after the last case tests negative.
