Red zone-green zone classification to be revised weekly: Centre to states
According to the health ministry, a district will be considered a Green Zone if there are no confirmed cases so far or there is no reported case for the last 21 days in the district. “It is further highlighted that based on field feedback and additional analysis at the state level, states may designate additional red or orange zones as appropriate. However, states may not relax the zonal classification of districts classified as communicated by the Ministry.”
