1. Centralized isolation medical observation was carried out for those who came to and returned from Chongqing in middle and high-risk areas 14 days, and nucleic acid detection was carried out on 1 0, 4, 7, 14 days/time respectively.
2. The counties (cities, districts and banners) where the middle and high-risk areas are located and other low-risk areas and counties (cities, districts and banners) with more reported infected people come to Chongqing and return to Chongqing for home isolation medical observation 14 days. Those who do not have the conditions for home isolation will be isolated in a centralized way. 1, 4, 7,1.
3. Those who come to Chongqing from other counties (cities, districts and banners) in the city where the middle-high risk area is located should provide negative proof of nucleic acid test within 48 hours, conduct two nucleic acid tests within 3 days after arriving in Chongqing (the interval between two sampling is at least 24 hours, and observe at home in principle before the two test results come out), and implement self-health monitoring for 7 days.
4. Those who come to Chongqing and those who return to Chongqing from cities with local cases but no middle-high risk areas should provide negative proof of nucleic acid test within 48 hours, conduct two nucleic acid tests within 3 days after arriving in Chongqing (the interval between sampling is at least 24 hours, and observe at home in principle before the results of the two tests come out), and implement self-health monitoring for 7 days.
5. Personnel in high-risk positions who come to Chongqing and return to Chongqing can provide proof that they have left their posts for more than 4 days 1 time, hold negative proof of nucleic acid test within 48 hours, and test1time within 24 hours after arriving in Chongqing; If there is no relevant proof, "self-health monitoring at home for 7 days" will be implemented, and 1 nucleic acid detection will be conducted on 1, 4, 7, 10 and 14 respectively.
