1. High-risk areas: There are more than 50 cases in COVID-19, and there is a cluster epidemic within 14 days.
2. Medium-risk areas: within 14 days, there were newly confirmed cases in COVID-19, and the cumulative number of confirmed cases in COVID-19 was no more than 50; More than 50 cases were diagnosed in total, and no cluster epidemic occurred within 14 days.
3. Low-risk areas: COVID-19 cases have not been confirmed, or no new confirmed cases have been added in 14 days.
Second, the division standard
1. Area: Streets and towns are the basic units.
2. Time: The longest incubation period in COVID-19 is based on 14 days.
3. Epidemic situation: * * The total number of cases in COVID-19, whether there is a clustering epidemic situation.
To sum up, the criteria for dividing high, medium and low risk areas of the epidemic are whether there are confirmed cases in COVID-19 within 14 days and how many confirmed cases there are in a street or area, and the specific criteria need to be appropriately adjusted according to the situation and changes of the epidemic situation in COVID-19.
Third, how to deal with it.
1. For high-risk areas, it is necessary to carry out the strategy of internal non-proliferation, external prevention and export, and strict control, and continue to do a good job in epidemic traffic control. If the epidemic situation in high-risk areas is effectively controlled, the scope of returning to work will be increased in an orderly manner.
2. For the medium-risk areas, the measures of "preventing external import and preventing internal proliferation" shall be implemented to restore normal production and life in an orderly manner as soon as possible. Organize personnel to return to their posts in an orderly manner, guide all employing enterprises to strictly implement epidemic prevention measures, and simultaneously promote epidemic prevention and control work and enterprises to resume work.
3. In low-risk areas, the strategy of "strictly preventing imports and making overall plans" will be implemented, and street traffic restrictions will be abolished to fully restore production and living order.
Color description of health codes in high schools and low-risk areas with the latest epidemic situation
First, the health code color
Holding a green health code means that you can go in and out normally when your body temperature is normal and well protected after testing;
Holding a yellow health code represents the need for home isolation and medical observation;
The red health code represents the need for centralized isolation, that is, the need for centralized isolation at the designated centralized isolation point.
Second, the color change of health code
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 is still normal green; If the holder of the green health code stays 1 hour after entering the middle or high-risk area, and the mobile phone can normally receive the roaming information, the health code will automatically change from the original green code to the yellow code or the red code.
2. When people with yellow code or red team enter the low-risk area, they can automatically record the time when they arrive at the low-risk area as long as they turn on their mobile phones. After 14 days of quarantine, and the person with the health code has not become a secret contact or COVID-19 case, the health code can be automatically converted into a normal green health code.
3. If the code holder becomes a close contact or a confirmed case, and the information is reported to the coding platform by the code holder himself, then the 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 platform of the coding company will change the red health code of the code holder back to the green health code 28 days after the date of recovery and discharge; For close contacts, from the day of contact to 28 days later, if they do not become cases, the platform will convert the red health code into the green health code.
