What are the meanings of Class A, Class B and Class C in Xi 'an epidemic?

First, what is the epidemic high school low risk area?

1. High-risk area: Generally speaking, there are more than 50 cases of COVID-19 in this area, and there is a cluster epidemic within 14 days.

2. Medium-risk areas: There are newly confirmed cases within 14 days, and the cumulative confirmed cases in COVID-19 are no more than 50; There were more than 50 confirmed cases in COVID-19, and there was no clustering epidemic in 14 days.

3. Low-risk areas: There are no confirmed cases in COVID-19 at present, or there are no new confirmed cases in 14 days.

Second, the 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: How many cases are there in total, and whether there is a cluster epidemic situation.

Generally speaking, the criteria for dividing high, medium and low risk areas are whether there are COVID-19 cases and how many COVID-19 cases in a street or town within 14 days. At the same time, the specific standards should be adjusted according to the epidemic trend in COVID-19.

Third, coping strategies.

1. In high-risk areas, the measures of "internal non-proliferation, external export prevention and strict control" are implemented, and the entry and exit control work is continuously improved. 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. In the moderate risk area, measures can be taken to prevent external input and internal diffusion and restore normal production and life in an orderly manner as soon as possible. Relevant organizers can return to their posts in an orderly manner, guide employers 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 traffic restrictions on roads and residential areas will be lifted to fully restore normal production and living order.

Color description of health code for high, medium and low epidemic risk levels.

First of all, the color of the health code.

Green health code means that you can go in and out normally on the premise that the temperature test shows no abnormality and personal protection is done well;

The yellow health code represents the need for home isolation and medical observation;

Finally, the red health code indicates the need for centralized isolation, that is, centralized isolation at the designated isolation point.

Second, the health code color transformation

The three colors of the health code will change according to the high, medium 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 will not change color, that is, it is normal green; If the person holding the green code 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 color from green code to yellow code or 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 quarantine 14 days, the health code will automatically become a normal green code, without making the code holder a secret contact or case.

3. If the code holder becomes a secret contact or a confirmed case and reports the information to the coding company platform by himself, the coding company platform will change the green health 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 back to the green health code 28 days after the code holder leaves the hospital. For close contacts, from the day of contact 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.

But what you need to know is 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 area. In addition, the division of high-,medium-and low-risk areas can't be fixed. Everyone needs to change their travel modes according to the epidemic situation in their own areas, so as to reduce the risk of infection in COVID-19.
