Methods/steps;
1 Implement the policy of external defense, internal defense and non-proliferation for the risk areas in the epidemic. Reduce personnel gathering and strengthen personnel protection.
Some key communities should be closed down for management.
3. Conduct centralized investigation of personnel in the middle-risk area to ensure that everyone has nucleic acid testing.
4. Isolate some people with positive results of nucleic acid test immediately, and investigate the action track of 14 days. Check all contact personnel and conduct prevention and control isolation.
For residents in medium-risk areas, check nucleic acid every 5 days.
As long as no positive patients are found in the test results of centralized isolation area 14 days, they can be reported. The joint prevention and control institutions in the State Council can be downgraded to low risk by the research decision of the municipal epidemic prevention headquarters. After a low-risk period of 2 1 day, if no positive patients are found, the risk can be lifted.
