(1) classification standard.
The places where cases and asymptomatic infected people live and workplaces and places with frequent activities and high risk of epidemic spread are classified as high-risk areas. In principle, the residential area (village) is defined as a unit, and the risk area can be adjusted according to the results of the mobile survey.
(2) Prevention and control measures.
Implement storage control measures, during which "stay at home and provide on-site service". If new infection cases are found during the closed period, the local joint prevention and control mechanism will organize risk judgment. According to the requirement of "one area, one policy", the closing time of the original control area can be extended in whole or in part.
(3) Bidding.
There was no new infection for 7 consecutive days, and all the people in the risk area completed a round of nucleic acid screening on the 7 th day and were negative, which was reduced to a moderate risk area; No new infection occurred for 3 consecutive days, and it was reduced to a low-risk area.
Second, the medium risk area.
(1) classification standard.
Cases and asymptomatic infected people stay for a certain period of time, and areas where there may be risks of epidemic spread, such as workplaces and activity places, are classified as medium-risk areas, and the scope of risk areas is defined according to the results of mobile investigation.
(2) Prevention and control measures.
During the implementation of control measures, "people don't leave the area, they take things at the wrong peak".
(3) Bidding.
There was no new infection for 7 consecutive days. On the seventh day, all the people in the risk area completed a round of nucleic acid screening, all of which were negative and reduced to a low-risk area.
Three. Low-risk area
Risk area refers to other areas of the county (city, district, banner) where the medium and high risk areas are located.
Carry out "personal protection to avoid aggregation" and leave the city with a 48-hour negative nucleic acid test certificate.
After all the high-risk areas are cleared, all counties (cities, districts and banners) will implement normalized prevention and control measures.
In addition, there are normalized prevention and control areas:
The fourth is the field of normalization prevention and control.
No epidemic counties (cities, districts, banners) should implement normalized prevention and control measures;
