2. red team was given to the temporary (returning) residents who lived in high-risk areas for less than 7 days, and centralized isolation medical observation measures were implemented for 7 days, and nucleic acid detection was carried out on 1, 2, 3, 5 and 7 days respectively.
3. The temporary (returning) residents who lived in the middle risk area for less than 7 days were given red team, and the medical observation measures were implemented for 7 days at home, and the nucleic acid detection was carried out on 1, 4 and 7 days respectively.
4. The management period of isolated medical observation shall be counted from the time of leaving the risk area, and the investigation time shall be traced back to 7 days from the date of adjusting the risk level locally. 5. Strictly implement the control measures of "7 days of centralized isolation medical observation and 3 days of home health monitoring" for entry personnel. Nucleic acid was detected on 1, 2, 3, 5 and 7 days after centralized isolation medical observation. After the centralized isolation was lifted, point-to-point closed-loop management was implemented to carry out home health monitoring, and nucleic acid detection was carried out on the third day of home health monitoring.
6. Give red team to close contacts, and strictly implement the control measures of "centralized isolation medical observation for 7 days and home health monitoring for 3 days". Nucleic acid was detected on 1, 2, 3, 5 and 7 days after centralized isolation medical observation. After the centralized isolation was lifted, peer-to-peer home health monitoring was implemented, and nucleic acid detection was carried out on the third day of home health monitoring.
