1. For those who have lived in high-risk areas for 7 days, medical observation was concentrated in isolation for 7 days, and nucleic acid detection was carried out on 1, 2, 3, 5 and 7 days respectively.
2. For those who have lived in the middle-risk area for less than 7 days, take home isolation medical observation for 7 days, and carry out nucleic acid detection (oropharynx) on 1, 4 and 7 days. 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.
3. Persons who have lived in low-risk areas (referring to other areas within the counties, cities, districts and banners where high-risk areas are located) for 7 days should complete two nucleic acid tests within 3 days, and do a good job in health monitoring.
