1. High-risk area: According to the principle, the living area of infected people, as well as the workplaces and activity places where the epidemic situation is likely to spread frequently are classified as high-risk areas, and the units in high-risk areas are generally units and buildings, which cannot be expanded at will; When the risk of epidemic spread is unclear or there is widespread community spread, the scope of high-risk areas can be appropriately adjusted and expanded;
2. Low-risk area: Other areas in counties (cities, districts and banners) where high-risk areas are located are low-risk areas.
Second, prevention and control measures
1. For high-risk areas, implement closed control measures: stay indoors and provide on-site services.
2. Take preventive measures for low-risk areas, that is, personal protection and avoiding gathering.
Third, cancel the standard.
1. High-risk area: No new infection cases occurred for 5 consecutive days, and it was adjusted to low-risk area. The high-risk areas that meet the relevant conditions should be unsealed in time.
2. Low-risk area: there is no high-risk area in the county (city, district and banner), and the low-risk area is adjusted to normal prevention and control.
Fourth, manage and control the overflow personnel in the risk field.
1. High-risk area: The requirements for the isolation of overflow personnel in high-risk areas are adjusted to "7-day home isolation", and they are not allowed to go out during the isolation period, and code management is implemented. Nucleic acid was detected on 1, 3, 5 and 7 days.
2. Low-risk area: People who live in the low-risk area of inflow area for 7 days will complete nucleic acid detection twice in 3 days, that is, twice in 3 days.
Note: The measures for the control of overflow personnel in risk areas are applicable to the floating personnel across provinces, and the management of overflow personnel in high-risk areas and medium-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 meaning of health code
Holding a green health code means that you can pass normally with normal body temperature and personal protection;
The yellow health code indicates that it is necessary to implement home health monitoring, do not go out unless necessary, and restrict access to public places;
Finally, the red health code means that the code holder needs to implement home isolation or centralized isolation for 7 days.
Second, the color change of health code
The three colors of the health code will change color according to the epidemic situation, high school and low-risk areas where the code holder enters and exits.
1, the holder of the green health code enters the low-risk area without special circumstances, and the health code will not change color, that is, it is normal green; If the holder of the green health code enters the middle or high-risk area and waits for one hour, the mobile phone can normally receive roaming information, and the health code will automatically change color, from the original green code to the yellow code or red team.
2. When people with code yellow or red team enter the low-risk area, as long as they turn on their mobile phones, the time to reach the low-risk area will be automatically recorded. After 7 days of isolation, the health code will be automatically converted into a green health code, if the person with the code does not become a secret contact or COVID-19's situation.
3. If the code holder becomes a close contact or case, after the code holder reports the information to the coding platform, the coding company platform will control the code holder's green code to turn red.
4. If the code holder is diagnosed as a case or a suspected case, the coding platform will change the red health code of the code holder back to the green health code after 7 days from the date of rehabilitation and discharge; For close contacts, if they do not become cases from the day of contact to 7 days later, the platform will turn the red health code back to the yellow health code, and after 3 days of home monitoring, it can be turned into a green health code.
However, everyone should understand that the health codes in different regions may be different, and pay more attention to the health codes that need to be used in their own regions. In addition, the division of high, medium and low risk areas is not static. Everyone should pay attention to the epidemic situation in their own areas, change their travel and reduce the spread of COVID-19's disease.
