COVID-19 IN TN: HOW ARE RED, ORANGE AND GREEN ZONES CLASSIFIED? UPDATED LIST FROM STATE GOVERNMENT!

In the third Lockdown that was imposed, the centre issued different set of guidelines for different zones. The norms to be followed and relaxations permitted varies from zone to zone. Hence, the segregation of zones has become an important point of discussion. The central government releases the list of orange, green and red zones on a weekly basis while state governments update almost on a daily basis. 

The basic definition and details about Red, Orange and Green Zone has been listed below:

Red Zones are areas that are severely affected by the Coronavirus outbreak. These districts or places are considered to be hotspots of the virus as per the guidelines issued by the Ministery of Health and Family Affairs (MOHFW). 

Red Zone

A district is classified as a Red Zone (hotspots) if it contributes to more than 80% to the total number of positive cases in India, if it contributes to more than 80 % of cases in its own state or if the district has a doubling rate (Time taken for the initial number of registered case to double) which is less than four days. Major cities that have been classified as red zones in India include, Delhi, Mumbai, Kolkata, Chennai, Bengaluru and Hyderabad. If a city falls into a red zone, it is further divided into different containment zones so that the spread of the virus could be monitored and effectively curbed. 

Orange Zone

Orange zones are areas and districts that have recorded a limited number of coronavirus cases and have not recorded a new rise in such cases. A hotspot district can get classified as an orange zone if no fresh cases are reported in 14 days. 

Green Zone

If a hotspot does not report positive case in 28 days, they are declared as Green Zones. For example, if Chennai does not report a positive case in 14 days, it will be classified as an orange zone. After getting classified as an orange zone, if it does not record any case for another 14 days, it will come under green zone.
