Division standard
1. Area: Streets and towns are the basic units.
2. Time: the longest incubation period in COVID-19-14 days is one unit.
3. Epidemic situation: How many cases are there in total, and whether there is a cluster epidemic situation.
In a word, the criteria for dividing high, medium and low-risk areas are whether there are COVID-19 cases in a street or community within 14 days and how many cases are confirmed in COVID-19. The specific criteria for dividing high, medium and low-risk areas should be adjusted according to the changes of COVID-19 epidemic situation.
How to deal with it
1. In high-risk areas, the strategy of "internal proliferation prevention, external export prevention and strict management" will be implemented, and traffic control of epidemic situation will continue to be done as much as possible. When the epidemic situation in high-risk areas is effectively controlled, the scope of resumption of work and production will be increased in an orderly manner.
2. Implementing the strategy of "introducing from outside and preventing from inside" in middle-risk areas can help people to resume their work and normal life as soon as possible. Relevant organization personnel can 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 and enterprises to resume work and production.
3. For low-risk areas, the strategy of strictly preventing imports and making overall plans should be implemented, the road restriction measures should be cancelled, and at the same time, the normal production and living order should be fully restored.
What are the early symptoms of COVID-19?
The early symptoms of COVID-19 virus infection are similar to those of general respiratory virus infection. The main manifestations are respiratory symptoms, such as fever, dry cough, sore throat, stuffy nose and runny nose. Fever is mostly low fever, and a few people have high fever. Some people also have other symptoms, such as fatigue, loss of smell and taste, muscle pain, conjunctivitis, and digestive tract symptoms, such as loss of appetite and diarrhea.
Some infected people have no clinical symptoms, which is what we call asymptomatic infected people. However, with the development of the disease course, these people may also have corresponding symptoms in the later stage.
Health code color conversion
The three colors of the health code will change according to the epidemic situation, high school and low-risk areas where the code holders go in and out.
1, the green code holder enters the low-risk area without special circumstances, and the health code does not change color, that is, it displays normal green; If the holder of the green health code stays for one hour after entering the medium or high-risk area, and the mobile phone can receive the roaming information normally, the health code will automatically change from the 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, as long as he turns on his mobile phone, the time of arrival in the low-risk area will be automatically recorded. After 14 days of quarantine, and the person holding the code has not become a close contact or COVID-19's case, the health code will be automatically changed to a normal green code.
3. If the code holder becomes a secret contact or case of COVID-19, and the information is reported to the platform of the coding company by the code holder himself, then the platform of the coding company will change the green code of the code holder to 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 to a green health code 28 days after the code holder leaves the hospital. And close contacts, from the day of contact with the case to 28 days later, if they do not become COVID-19 cases, then the red health code will be turned back to the green health code by the coding platform.
However, you should know that the health codes in different places may be different, so pay more attention to the health codes that need to be used in your own area. In addition, the division of high, medium and low risk areas is not static, so you'd better change your itinerary according to the epidemic situation in your own area to reduce the spread of COVID-19's disease.
