1. Implement the management measures of "7-day centralized isolation medical observation and 3-day home health monitoring" for entry personnel, and conduct nucleic acid detection (oropharynx) for 1, 2, 3, 5 and 7 days centralized isolation medical observation personnel; On the third day of the 3-day family health monitoring, a (oropharynx) nucleic acid test was conducted to monitor the body temperature and symptoms during the period. Do not go out. If you need to go out under special circumstances such as medical care, do a good job of personal protection and avoid taking public transport.

2. People living in high-risk areas in recent 7 days were isolated for medical observation for 7 days, and nucleic acid (oropharynx) was detected on 1, 2, 3, 5 and 7 days.

3. For those who have lived in the moderately dangerous area for the last 7 days, take 7-day home isolation medical observation, and carry out (oropharynx) nucleic acid detection on 1, 4 and 7-day home isolation medical observation personnel. Those who do not have the conditions for home isolation medical observation shall adopt centralized isolation medical observation, and the management period shall start from leaving the risk area.

4. For those who have lived in low-risk areas for the last 7 days, they should complete two nucleic acid tests within 3 days after their arrival, and do a good job in health monitoring.
