First, standards for delineating high- and low-risk areas

1. High-risk areas: In principle, areas where infected people live and workplaces where people move around frequently and where the possibility of epidemic spread is relatively high , activity venues and other areas are classified as high-risk areas. The units in high-risk areas are generally units and buildings and cannot be expanded at will; when the risk of epidemic transmission cannot be clearly determined or there is widespread community transmission, the expansion can be appropriately adjusted Scope of high-risk areas;

2. Low-risk areas: Other areas in the county (city, district, banner) where the high-risk area is located are low-risk areas.

2. Prevention and control measures

1. Implement lockdown measures in high-risk areas: door-to-door services without leaving home.

2. Implement preventive measures in low-risk areas, namely: personal protection and avoidance of gatherings.

Third, lifting criteria

1. High-risk area: There are no new infections for 5 consecutive days, and it is adjusted to a low-risk area. High-risk areas that meet relevant conditions must be unblocked in a timely manner.

2. Low-risk areas: There are no high-risk areas in the county (city, district, banner), and low-risk areas are adjusted to normalized prevention and control.

Fourth. Control of spillover personnel in risk areas

1. High-risk areas: The isolation requirements for spillover personnel in high-risk areas are adjusted to "7-day home quarantine". During the isolation period, they are not allowed to go out and Code management. A nucleic acid test will be conducted on the 1st, 3rd, 5th and 7th days of isolation.

2. Low-risk areas: People with a seven-day stay in low-risk areas must complete nucleic acid testing twice within three days, that is, two tests in three days.

Note: The control measures for spillover personnel in risk areas apply to cross-provincial mobile personnel. The management of spillover personnel in high-risk areas and medium-risk areas within the jurisdiction of each province (autonomous region, municipality directly under the Central Government) is formulated by each locality.

Instructions on the color of the health code in areas with high, medium and low risk levels of the epidemic

1. Meaning of the color of the health code

Holding a green health code means that the body temperature is normal and Under the condition of good personal protection, you can pass normally;

Yellow health code means that you need to implement home health monitoring, do not go out unless necessary, and access to public places is restricted;

Finally, the red health code means that the code holder needs to be quarantined at home or in a centralized quarantine for 7 days.

2. Color changes of the health code

The three colors of the health code will change according to the high, medium and low risk areas of the epidemic that the code holder enters and exits.

1. If a person holding a green health code enters a low-risk area without special circumstances, the health code will not change color, that is, normal green; if a person holding a green health code enters a medium or high-risk area, After entering the area, wait for an hour, and the mobile phone can receive communication roaming information normally, then the health code will automatically change color, from the original green code to a yellow code or a red code.

2. After a person holding a yellow code or a red code enters a low-risk area, as long as the mobile phone is turned on, the time of arrival in the low-risk area will be automatically recorded. After being quarantined for 7 days and the code holder has not become a close contact or If there is a case of COVID-19, the health code will automatically change to a green health code.

3. If the code holder becomes a close contact or a case, after the code holder reports the information to the Token platform, the Token company platform will turn the code holder's green code into red.

4. If the code holder is diagnosed as a case or suspected case, then 7 days from the day of recovery and discharge, the coding platform will convert the red health code of the code holder back to a green health code; and close contact If the person does not become a case from the day of contact to 7 days later, the platform will convert the red health code back to a yellow health code. After 3 days of home monitoring, it can be converted to a green health code.

But 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 your area. In addition, the division of high, medium and low risk areas for the epidemic is not static, so everyone should pay attention to the epidemic situation in their own area, change their travel, and reduce the spread of COVID-19.
