First, the risk area delineation criteria
1. High-risk area: In principle, the area where infected people live and the activities and workplaces with high risk of epidemic spread are classified as high-risk areas, and the units in high-risk areas are generally units and buildings, and shall not be expanded at will; When the risk of epidemic spread is unclear or there is a large-scale community spread risk, the scope of high-risk areas can be appropriately expanded and adjusted;
2. Low-risk area: Other areas in counties (cities, districts and banners) where high-risk areas are located are low-risk areas.
Second, what are the coping strategies?
1. To implement the sealing and control measures in high-risk areas, it is necessary to "stay at home and provide on-site service".
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 infections were found for 5 consecutive days, and it was reduced to low-risk area. If the high-risk area meets the requirements, it 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 changed to normal prevention and control.
Four. Control measures of risk area overflow
1. High-risk area: The control measures for overflow personnel in high-risk area are adjusted to "7-day home isolation", and they are not allowed to go out during the isolation period, and code management is implemented. On days 1, 3 and 5 of isolation, 1 nucleic acid was detected on day 7.
2. Low-risk area: People who live in low-risk area for 7 days will complete nucleic acid detection twice within 3 days, that is, twice every three days.
In addition, the control measures for spillover risk personnel are applicable to inter-provincial personnel flow, and the control measures for spillover risk personnel in high-risk areas and medium-risk areas within the jurisdiction of each province are formulated and released by all localities.
Color description of regional health codes with high, medium and low risk levels in the latest epidemic situation
One or three health code colors
Holding a green health code means that you can pass normally if the temperature test shows no abnormality and you are well protected;
The yellow health code represents the need for home health monitoring, not going out unless necessary, and restricting access to public places;
Finally, the red health code represents the need for home isolation or centralized isolation.
Second, the health code color transformation
The three colors of the health code will change color according to the high, medium and low risk areas where the code holder enters and exits.
1, the green code holder enters the low-risk area without special circumstances, and the health code will not change color, that is, it will display normal green; If the green code holder enters the middle and high risk area, the mobile phone can receive roaming information normally when waiting for 1 hour, and the health code will automatically change from green code to yellow code or red code.
2. When a person with a yellow code or red team enters a low-risk area, you can automatically record the time of arrival in the low-risk area as long as you turn on your mobile phone. After 7 days of isolation, if the person with the health code does not become a secret contact or COVID-19 case, the health code will automatically become a normal green health code.
3. If the health code holder becomes a close contact or case of COVID-19, and the information is reported to the coding platform by the code holder himself, the coding company platform will turn the green code of the code holder into 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 into a 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 into a yellow health code, and it will turn into a green code after 3 days of home monitoring.
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 needs to pay attention to the epidemic situation in their own areas and change their itinerary to reduce the risk of COVID-19's disease infection.
