One, for individuals from high-risk areas, implement a “7-day home isolation medical observation,” during which they are to be coded managed, not allowed to go out, and undergo nucleic acid testing once on the 1st, 3rd, 5th, and 7th day of home isolation medical observation. The management period starts from the day of leaving the high-risk area and continues until the 7th day is reached. Two, for individuals from low-risk areas, complete two nucleic acid tests within 3 days, with an interval of 24 hours between each test. Three, for incoming individuals, implement a “5-day centralized isolation and 3-day home isolation” measure, during which they are to be coded managed, not allowed to go out, and undergo nucleic acid testing once on the 1st, 2nd, 3rd, and 5th day of centralized isolation, and once on the 1st and 3rd day of home isolation medical observation.

  1. For individuals from high-risk areas, implement a “7-day home quarantine medical observation.” During this period, individuals must be coded for management, not allowed to go out, and a nucleic acid test should be conducted once on the 1st, 3rd, 5th, and 7th day of home quarantine medical observation. The management period starts from the day of leaving the high-risk area and continues until the 7th day is reached. 2. For individuals from low-risk areas, complete two nucleic acid tests within 3 days, with an interval of 24 hours between each test. 3. For incoming individuals, implement a “5-day centralized quarantine and 3-day home quarantine.” During this period, individuals must be coded for management, not allowed to go out, and a nucleic acid test should be conducted once on the 1st, 2nd, 3rd, and 5th day of centralized quarantine. For home quarantine medical observation, a nucleic acid test should be conducted once on the 1st and 3rd day.
