1. High-risk areas: the places where cases and asymptomatic infected people live, as well as places with frequent activities and high risk of epidemic spread such as workplaces, are classified as high-risk areas. In principle, residential areas (villages) are designated units, and risk areas can be adjusted according to the flow adjustment results.
2. Medium-risk areas: areas where asymptomatic infected persons and cases stay and flow for a period of time, and there may be a certain risk of epidemic spread, such as activity places and workplaces, are classified as medium-risk areas. Determine the risk area according to the flow adjustment result.
3. Low-risk areas: Other areas in counties (districts, cities and banners) where high and medium-risk areas are located are low-risk areas.
Second, what are the coping strategies?
1. For high-risk areas, measures should be taken to control the blockade and implement "stay at home and provide on-site service".
2. Control measures should be implemented in the medium-risk area: if you can't leave the area, please take things at the wrong peak.
3. Take preventive measures in low-risk areas: personal protection and avoiding gathering.
Third, the risk area lifting standards
1. High-risk area: No new infection cases were found 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 moderate risk area; There was no new infection for three consecutive days, and then it fell to a low-risk area.
2. Medium risk area: No new infection was found for 7 consecutive days. On the seventh day, all the people in the risk area were negative for nucleic acid screening, which was reduced to a low-risk area.
3. Low-risk areas: There are no medium-risk areas and high-risk areas in counties (cities, districts and banners), and the low-risk areas are adjusted to normal prevention and control.
Four. Management and control of overflow risk personnel
1. High-risk areas: People who live in high-risk areas for 7 days shall be observed in isolation in the inflow area for 7 days. Implement centralized isolation measures for leakage in high-risk areas for 7 days. Nucleic acid detection was carried out on 1, 2, 3, 5 and 7 days (the management period was calculated from leaving the risk area) of centralized isolation medical observation.
2. Moderate danger zone: People who live in the moderate danger zone for 7 days will be observed in isolation at home for 7 days. Nucleic acid was detected on days 1, 4, and 7 of home medical observation. Those who do not have the conditions for home isolation observation will be isolated for 7 days (the management period starts from leaving the risk area).
3. Low-risk areas: For people who have lived in low-risk areas for 7 days, they will complete two nucleic acid tests within 3 days (two tests within 3 days).
Note: Risk area spillover control measures are applicable to people flowing across provinces (autonomous regions and municipalities directly under the Central Government), and the spillover management of medium-risk areas and high-risk areas within the jurisdiction of provinces (autonomous regions and municipalities directly under the Central Government) is formulated by local governments.
Color description of health code in high, medium and low risk areas of epidemic situation
First, the color of the health code.
Holding a green health code means that you can pass normally when your body temperature is normal and your protection is good.
The yellow code indicates that the code holder needs to carry out family health monitoring and restrict access to public places;
Holding a red health code means that the code holder should adopt centralized isolation or home isolation.
Second, the health code color change
The three colors of the health code will change according to the high, medium and low risk areas where the code holder enters and exits.
1. If the green code holder enters the low-risk area without special circumstances, the health code will not change color, that is, it is normal green; People with green codes stay for one hour after entering the high or medium risk area, and the mobile phone can normally receive communication roaming information, and the health code will automatically change from the original green code to the yellow code or the red code.
2. When people from the yellow code or red team enter the low-risk area, they can automatically record the arrival time of the low-risk area as long as they turn on their mobile phones. After 7 days of isolation, if the code holder does not become a close contact or COVID-19 case, the health code will automatically change back to normal green code.
3. If the code holder becomes a close contact or a confirmed case, after the code holder reports the information to the code distribution company platform, the code distribution company platform will turn the code holder's green health code into red.
4. If the code holder is diagnosed as a case or a suspected case, the platform of the code issuing company will convert the red health code of the code holder into a green health code after 7 days from the date of recovery and discharge; For close contacts, from the day of contact to 7 days later, if there is no COVID-19 case, the code platform will change the red health code to the yellow health code, and after 3 days of home monitoring, it can be changed to the green code.
However, we should understand that the health codes in different regions may be different, so we should pay more attention to the health codes that need to be used in your region. In addition, the division of high-,medium-and low-risk areas can't be fixed, so you'd better adjust your itinerary according to the epidemic situation in your own area, so as to reduce the spread rate of the disease in COVID-19.
