Health code "yellow code" processing:
1. In the past 14 days, people who once lived in counties and cities with high-risk areas or had potential close contacts (people whose electronic health code showed yellow code) were isolated at home for 7 days and monitored at home for self-health, and nucleic acid detection was carried out on 1, 3, 7 and 14 days respectively.
2. The key population (people whose electronic health code shows yellow code) that the confirmed cases or asymptomatic infected people may contact were monitored at home for 7 days, and the nucleic acid was detected at 1, 3 and 7 days respectively.
3. From 14, the people living in the city where the high-risk area is located were monitored for 7 days at home, and the nucleic acid was detected on 1 4.
4. In recent 14 days, people who have lived in the city where the middle-risk area is located (electronic health code display personnel) were monitored at home for 7 days, and the nucleic acid was detected on the first day.
