Specifically, the closed control area is closed and isolated, and the door is served at home. In the control area, it is strictly forbidden to take prevention and control measures such as people leaving the area and gathering. The prevention zone will strengthen social control and strictly limit the scale of personnel gathering. To implement the measures of these three types of classified control areas, we must strengthen the work system of community prevention and control, strengthen the work system of community epidemic prevention and control, and establish a "three-level guarantee" system. District and county cadres should cover township streets, township street cadres should cover administrative villages and communities, and administrative villages and community cadres should cover households. Implement a grid community management mechanism to ensure that all measures such as investigation, nucleic acid detection, traceability, isolation control, health monitoring and service guarantee are in place.
