1. People who have recently come from or passed through the low-risk area where the middle-high risk area is located or where the local nucleic acid test is positive and confirmed must have a negative nucleic acid test certificate within 48 hours, or be able to produce a health code that includes the negative nucleic acid test certificate within 48 hours. If the body temperature is normal, the nucleic acid samples collected as required can flow in an orderly manner under the premise of personal protection. For those who cannot provide negative proof of nucleic acid testing within 48 hours, nucleic acid testing must be carried out at the designated place. After obtaining negative proof, it can flow in an orderly manner, and then cooperate with nucleic acid testing according to the stay time in Xu;

2. Those who have crossed the track with the confirmed cases in the recent 14 days, all those who come from or pass through the middle-high risk areas and the districts and cities where they are located, or those who come back from the districts and cities where the local nucleic acid positive confirmed cases are located, should report to their communities at the first time, truthfully provide the activity track and personal health information, and cooperate with nucleic acid detection and health monitoring.

3. For those who come from middle and high-risk areas or have tracked and crossed the confirmed cases with positive nucleic acid detection, it is necessary to conduct centralized isolation observation for 14 days, and do a good job in nucleic acid detection as required. After lifting the centralized isolation observation, it should be included in the community grid management, and the home health monitoring for 7 days, during which the body temperature, symptoms and other health monitoring, nucleic acid detection;

4. There are many recent cases. Please pay close attention to the adjustment of high-risk areas and the positive and confirmed cases of local nucleic acid testing, and adjust the prevention and control policies for arrival in time;

5. Carry out nucleic acid detection on the personnel coming to Xu, and report and standardize in time if any abnormality is found.

6. From1.10, mainlanders who come to Xu through bus stations, railway stations and airports are required to provide proof of negative nucleic acid within 48 hours. If they can't provide it, guide them to conduct nucleic acid testing on the spot.
