Epidemic risk area level, epidemic risk level classification

The level of epidemic risk area is delineated by the local epidemic prevention and control headquarters according to the size of the epidemic transmission risk, and is divided into three levels: high, medium and low risk areas. Areas that are generally classified as high-risk are where cases and asymptomatic infections live, as well as areas with high activity and a high risk of epidemic transmission. Areas such as places of work and activities are classified as high-risk areas.

Designated as medium-risk areas are areas such as work and activity places where cases and asymptomatic infected people stay and move for a certain period of time, and may have the risk of epidemic transmission. Other areas in the counties (cities, districts, banners) where medium- and high-risk areas are located are low-risk areas.

As of 11 o'clock on September 10, there are 1,283 high-risk areas in the country, involving 24 provinces (autonomous regions and municipalities directly under the central government) and the Xinjiang Production and Construction Corps, and 64 districted cities (districts); 1,548 medium-risk areas, involving 26 provinces (autonomous regions and municipalities directly under the central government), the Xinjiang Production and Construction Corps, and 80 districted cities (districts); 251 low-risk areas, involving 25 provinces (autonomous regions and municipalities directly under the central government), the Xinjiang Production and Construction Corps, and 85 districted cities (districts).

Low-risk areas: areas where there are no confirmed cases of the new coronavirus, or where there have been no new confirmed cases for 14 consecutive days.

Medium-risk areas: refers to the total number of newly confirmed cases within 14 days does not exceed 50, or the total number of cases has exceeded 15, but there is no cluster outbreak within 14 days.

High-risk areas: More than 50 COVID cases in total and clusters within 14 days.

One. High-risk areas.

1) Classification criteria.

Designate high-risk areas where cases and asymptomatic infections live, as well as workplaces and venues with high activity and a high risk of transmission. In principle, the residential area (village) is delineated, and the scope of the risk area can be adjusted according to the results of the flow survey.

2) Prevention and control measures.

Containment control measures were implemented during which "stay at home and provide door-to-door services". If a new infected person is found during the closure period, the local joint prevention and control mechanism will organize a risk assessment. In accordance with the requirements of "one zone, one policy", the closure time of the original control area can be extended in whole or in part.

3) Upgrading. There were no new infections for 7 consecutive days, and all the people in the risk area completed a round of nucleic acid screening on the 7th day and were negative, and were reduced to the moderate risk area; There were no new infections for 3 consecutive days, and it was reduced to a low-risk area.

Second, the medium-risk zone.

1) Classification criteria.

Cases and asymptomatic infected persons stay and move for a certain period of time, and workplaces, activity venues, and other areas where there may be a risk of the spread of the epidemic are classified as medium-risk areas, and the scope of risk areas is to be delineated on the basis of the results of the mobile survey.

2) Prevention and control measures.

During the implementation of control measures, "people do not leave the area, and things are taken at staggered peaks".

3) Upgrading. There were no new infections for 7 consecutive days, and on the 7th day, all people in the risk area completed a round of nucleic acid screening and were negative, which was reduced to a low-risk area.

Three. Low-risk areas.

Risk areas refer to other areas in the counties (cities, districts, banners) where medium and high risk areas are located.

Implement "personal protection and avoid gatherings", and leave the city with a 48-hour negative nucleic acid test certificate.

After all medium- and high-risk areas are lifted, all counties (cities, districts, banners) will implement normalized prevention and control measures.

In addition, there are normalized prevention and control areas:

Fourth, the field of normalized prevention and control.

Counties (cities, districts, banners) where no epidemic has occurred shall implement normalized prevention and control measures;

In general, the criteria for dividing high, medium and low risk areas are based on whether there are confirmed cases of new crown in a street or community within 14 days and how many confirmed new crown cases there are, and the specific classification standards need to be adjusted in a timely manner according to the changes in the new crown pneumonia epidemic.

1. Region: Take streets and towns as the basic units.

3. Epidemic situation: how many new crown pneumonia cases are total, and whether there is a cluster of epidemics.

How to respond: 1. Implement the strategy of "internal prevention of proliferation, external prevention of export, and strict control" for high-risk areas, and continue to focus on epidemic prevention and control. When the epidemic situation in high-risk areas is effectively controlled, the scope of resumption of work and production will be expanded in an orderly manner.

2. Medium-risk areas should implement the strategy of "preventing foreign importation and internal proliferation", and resume work and normal life as soon as possible and in an orderly manner. Relevant personnel can return to work in an orderly manner, and epidemic prevention and control and enterprise resumption of work can be promoted simultaneously.

3. For low-risk areas, the implementation of "strict prevention of importation, overall consideration" measures, cancel the road restriction measures, and at the same time fully restore the order of production and life.
