1. Sub-close contacts refer to close contacts. This kind of crowd refers to people who have had close contact with close contacts for the first time, such as people who live, work, eat and entertain in the same closed environment, but have not taken effective protective measures.
2. Sub-secret connection requires at least 7 days of centralized isolation +7 days of home isolation. If all the nucleic acid test results of the sub-close contact and its corresponding close contact are negative within 7 days, the sub-close contact can be released from centralized isolation after 7 days. In the 7-day home isolation, nucleic acid should be done on the 2 nd and 7 th days.
3. If the nucleic acid detection result corresponding to the second secret communication is positive, change the second secret communication to secret communication management (i.e. 14 days of centralized isolation +7 days of home health observation).
For close contacts, the management measures of "7-day centralized isolation +3-day home health monitoring" will be adjusted to "5-day centralized isolation +3-day home isolation", during which code management will be implemented and they are not allowed to go out. On 1, 2, 3 and 5 days, medical observation was concentrated and 1 nucleic acid was detected respectively. On 1 and 3 days, medical observation was isolated at home and 1 nucleic acid was detected respectively.
In 2022, the management measures of "5 days centralized isolation +3 days home isolation" will be implemented for close contacts. The 1 nucleic acid was detected on the 2nd, 3rd and 5th days of centralized isolation, and the 1 nucleic acid was detected on the 3rd day of home isolation.
