1. High-risk area: It means that there are more than 50 cases in COVID-19, and there is a cluster epidemic within 14 days.
2. Medium-risk area: within 14 days, there were newly confirmed cases in COVID-19, and the cumulative confirmed cases in COVID-19 did not exceed 50; More than 50 cases were confirmed, and there was no clustering epidemic within 14 days.
3. Low-risk areas: COVID-19 cases have not been diagnosed at present, or COVID-19 cases have not been diagnosed for 14 days.
Risk area division standard
1. Area: Streets and towns are the basic units.
2. Time: the longest incubation period in COVID-19 is-14 days.
3. Epidemic situation: the total number of cases, whether there is a cluster epidemic situation.
In a word, the criteria for dividing high, medium and low risk areas of epidemic situation are to divide a street or community into three risk levels according to whether there are COVID-19 cases and how many COVID-19 cases in 14 days, and the specific criteria should be adjusted according to the situation and changes of COVID-19 epidemic situation.
1. In high-risk areas, the policy of internal non-proliferation, external export prevention and strict control will be implemented, and we will continue to do our best to prevent and control the epidemic situation. 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. In the middle risk area, normal production and life can be restored in an orderly manner through external measures to prevent import and internal measures to prevent proliferation. Organize personnel to return to their posts in an orderly manner, guide employers to strictly implement epidemic prevention work, and unanimously promote epidemic prevention and control work and enterprises to resume work and production.
3. In low-risk areas, we can implement the strategy of "strictly preventing imports and making overall plans", cancel street restrictions and restore normal life order in an all-round way.
First, the color meaning of health code
Holding a green health code means that it can pass normally if there is no abnormality after the temperature test and it is well protected;
Holding a yellow health code means that the code holder should be isolated at home for medical observation;
Second, the color change of health code
The three colors of health code will change according to the high, medium and low risk areas where the code holder enters and exits.
1. When a person with a green code enters a low-risk area without special circumstances, the health code will not change color, that is, it is normal green; If the green code holder stays for one hour after entering the middle and high risk area, the mobile phone can receive roaming information normally, and the health code will automatically change from the original green code to the yellow code or the red code.
2. After the yellow code or red code holder enters the low-risk area, he can automatically record the time of arrival in the low-risk area as long as he turns on his mobile phone. After 14 days of isolation, and the code holder has not become a secret contact or COVID-19, the health code will be automatically converted into a green health code.
