(2) After arriving in Tianjin, in principle, a "landing inspection" should be conducted at airports, railway stations, long-distance passenger stations, expressways and intersections with nucleic acid sampling points. A nucleic acid test should be conducted within 6 hours after arrival in Tianjin at the latest, and the second nucleic acid test should be completed within 72 hours after an interval of 24 hours. Don't go out "unnecessarily" until you get a negative result. For commuters in Beijing, Tianjin and Hebei, the risk area is implemented according to the current policy, and negative nucleic acid test certificates are checked in other areas within 72 hours.
(3) Persons who have lived in low-risk areas for less than 7 days shall implement the verification system of negative proof of nucleic acid within 48 hours before arriving in Tianjin, and carry out "daily detection" of nucleic acid for 3 consecutive days after arriving in Tianjin (the first detection is "landing detection" in principle, and the interval between single sampling is 24 hours within 6 hours at the latest).
(4) People who live in a moderately dangerous area for less than 7 days should be observed in isolation at home for 7 days, and their nucleic acids should be detected at 1, 4 and 7 days. The management period starts from leaving the risk area. If there is no isolation observation condition at home, centralized isolation observation shall be implemented.
(5) Persons who have lived in high-risk areas for 7 days shall be subjected to centralized isolation medical observation for 7 days, and nucleic acid detection shall be carried out on 1, 2, 3, 5 and 7 days, and the management period shall be counted from leaving the high-risk areas.
(6) Relevant personnel shall carry out health management according to the relevant requirements of the state and Tianjin, and carry out nucleic acid detection with corresponding frequency.
