The government has updated the list of hotspots across the country after a secretary level video conference meeting on April 30 with the states for the week after May 3.
As per a letter released by the Union Health Ministry, "The districts were earlier designated as hotspots / red-zones, orange zones and green zones primarily based on the cumulative cases reported and the doubling rate.
Since recovery rates have gone up, the districts are now being designated across various zones duly broad-basing the criteria."
Based on the new guidelines issued by the Ministry of Health, all districts in the country have been classified as hotspots and non-hotspots based on whether or not confirmed COVID-19 cases have been reported there.
Moreover, it says that the classification is multi-factorial and takes into
consideration incidence of cases, doubling rate, extent of testing and surveillance feedback to classify the districts.
