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: there are newly confirmed cases within 14 days, and the cumulative confirmed cases in COVID-19 are no more than 50; More than 50 cases were confirmed in COVID-19, and there was no clustering epidemic within 14 days.
3. Low-risk areas: there are no confirmed cases in COVID-19, or there are no new confirmed cases in COVID-19 14 days.
Second, the division standard
1, region: street or township as the basic unit.
2. Time: the longest incubation period in COVID-19 is-14 days.
3. Epidemic situation: how many cases have been accumulated, and whether there is a clustering epidemic situation.
In a word, the criteria for dividing the high, medium and low risk areas of the epidemic situation are to divide the three risk levels according to whether there are COVID-19 cases and the number of confirmed cases in a street or area within 14 days, and the specific criteria need to be appropriately adjusted according to the trend of the epidemic situation in COVID-19.
Third, coping strategies.
1. For high-risk areas, internal non-proliferation, external export prevention and strict control measures should be implemented, and continuous efforts should be made to control access. When the epidemic situation in high-risk areas is effectively controlled, the scope of resumption of work will be increased in an orderly manner.
2. For medium-risk areas, adopting the strategy of "introducing from outside and preventing from inside" can help them to resume their work and normal life in an orderly manner. Organizers can first return to their posts in an orderly manner, guide employers to strictly implement epidemic prevention measures, and simultaneously promote epidemic prevention and control and enterprises to resume work and production.
3. For low-risk areas, measures should be taken to prevent imports, make overall plans, cancel road restrictions, and restore normal life order in an all-round way.
The color description of the latest epidemic area health code has three risk levels: high school, low middle school and low middle school.
First, the color meaning of health code
Holding a green health code means that you can enter and exit normally under the premise of normal temperature detection and good protection;
Holding a yellow health code means that the code holder needs to implement home isolation and then carry out medical observation;
Finally, the red health code represents the need for centralized isolation, that is, the need to go to the designated centralized isolation point for centralized isolation.
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, so the health code will not change color, that is, it will still be normal green; If the green code holder enters the high or medium risk area and waits for one hour, 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. 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 14 days of isolation, the code holder does not become a secret joint or case, and the health code will automatically change back to the normal green code.
3. If the code holder becomes a close contact or case and reports information to the coding company platform, 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 28 days after the date of rehabilitation and discharge; For close contacts, from the day of contact with the case to 28 days later, if it does not become a case, the red health code will be converted into a green health code by the coding platform.
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. Moreover, the division of high, medium and low-risk areas will not remain unchanged. Everyone needs to pay attention to the epidemic situation in their own areas, adjust their travel and reduce the transmission probability in COVID-19.
