High risk Medium risk area criteria, high risk area classification criteria

High-risk areas, generally cases and asymptomatic infections.

Places of residence, as well as areas such as workplaces and activities with high activity and a high risk of epidemic transmission.

In principle, high-risk areas are to be demarcated on the basis of residential communities (villages), and the scope of risk areas can be adjusted according to the results of flow investigation and judgment, and closure and control measures such as "staying at home and providing door-to-door services" can be adopted. The high-risk area has no new infections for 7 consecutive days, and it has been reduced to a medium-risk area.

The medium-risk area has no new infections for 3 consecutive days, and it has been reduced to a low-risk area.

In other areas, 7-day centralized isolation and medical observation measures will be adopted for those who have a history of travel or residence in high-risk areas in the past 7 days.

Medium-risk areas.

Generally, it is an area where cases and asymptomatic infected people stay and move for a certain period of time, and there may be a risk of epidemic transmission. The scope of the risk area is delineated according to the results of the flow survey. The medium-risk area has adopted control measures such as "people do not leave the area and take things at staggered peaks", and no new infections have been reduced to a low-risk area for 7 consecutive days.

In other areas, people with a 7-day history of travel and residence in medium-risk areas will be placed under 7-day home isolation medical observation, and a nucleic acid test will be carried out on the first day of home isolation medical observation; If the conditions for home isolation medical observation are not available, centralized isolation medical observation shall be adopted; The management period is calculated from the time you leave the risk area.

In the ninth version of the prevention and control plan, high-risk areas refer to the residences of cases and asymptomatic infected people, as well as areas such as workplaces and activity places with frequent activities and a high risk of epidemic transmission. In principle, high-risk areas are to be demarcated on the basis of the residential community or village, and the scope of the risk area can be judged and adjusted based on the results of epidemiological investigations. High-risk areas have adopted the closure and control measures of "staying at home and providing door-to-door services".

If there are no new infections in a high-risk area for 7 consecutive days, it can be downgraded to a medium-risk area, and then if there are no new infections for 3 consecutive days, it can be downgraded to a low-risk area. For personnel in high-risk areas with cross-regional spillover, 7 days of centralized isolation medical observation will be adopted. A nucleic acid test will be carried out on the first day of centralized isolation.

Medium-risk areas refer to areas such as work and activity where cases and asymptomatic infected people stay and move for a certain period of time and may have the risk of epidemic transmission. The delineation of risk zones is based on the results of epidemiological investigations. The medium-risk area adopts the control measures of "people do not go out of the area and take things at staggered peaks".

If there are no new infections for 7 consecutive days, it can be reduced to a low-risk area. For people in medium-risk areas who overflow across regions, 7 days of home medical observation will be adopted, and a nucleic acid test will be carried out on each day during the home medical observation period. If the conditions for home isolation are not available, centralized isolation medical observation shall be adopted.

Other areas in the counties (cities, districts, banners) where medium- and high-risk areas are located are designated as low-risk areas. Low-risk areas take precautionary measures of "personal protection and avoiding gatherings". Persons in low-risk areas who leave their area or city should hold a 48-hour negative nucleic acid test certificate.

For people in low-risk areas who go out across regions, there is no need to take isolation and control measures, but they are required to complete two nucleic acid tests within 3 days and do a good job of personal health monitoring.

Criteria for dividing high-risk areas: The places where cases and asymptomatic infected people live, as well as areas such as places of work and activities with frequent activities and a high risk of epidemic transmission, are classified as high-risk areas. In principle, it is delineated on the basis of residential quarters (villages), and the scope of risk areas can be adjusted according to the results of flow surveys.

Criteria for the classification of medium-risk areas: Medium-risk areas such as work and activity sites where cases and asymptomatic infected persons stay and move for a certain period of time and may have the risk of epidemic transmission are classified as medium-risk areas, and the scope of risk areas is delineated according to the results of the flow survey.

The first is the region, with streets and townships as the basic units. The second is time, and the longest incubation period is 14 days for one unit. The third is the epidemic, how many cases there are, and whether there is a cluster outbreak.

The specific criterion is whether there are confirmed cases of new crown pneumonia in a street within 14 days, and how many, are divided. The specific classification criteria should also be adjusted according to the situation and changes of the epidemic. (1) High-risk areas:

The cumulative number of cases exceeded 50, and there were clusters within 14 days. (2) Medium-risk areas: There are new confirmed cases within 14 days, the cumulative number of confirmed cases does not exceed 50, or the cumulative number of confirmed cases exceeds 50, and there is no cluster epidemic within 14 days.

3) Low-risk areas: no confirmed cases or no new confirmed cases for 14 consecutive days.

The criteria for identifying medium- and high-risk areas are as follows:

1. Region, with streets and towns as the basic units;

2. Time, the longest incubation period is 14 days for one unit;

3. The epidemic, how many cases there are, and whether there is a cluster outbreak.

If there are new confirmed cases within 14 days, and the cumulative number of confirmed cases does not exceed 50, it will be recognized as a medium and high-risk area. On the basis of the measures taken in low-risk areas, preparations should be made for medical treatment, disease control and prevention and other materials and personnel, and isolation sites and control personnel should be accurately determined for the epidemic discovered.

High-risk areas: generally the places where cases and asymptomatic infections live, as well as areas such as workplaces and activities with frequent activities and a high risk of epidemic transmission; Medium-risk areas: Generally areas where cases and asymptomatic infected people stay and move for a certain period of time, and where there may be a risk of epidemic transmission.

High-risk area: The cumulative number of confirmed cases of new crown in or within the district is more than 50, and there is a cluster risk within 14 days, and the medium-risk area: the cumulative number of new crown cases in the district or within the district is less than 50 cases, but there is no cluster risk within 14 days.

High-risk areas are those where multiple people are infected and there is still a risk of transmission, and there are suspected patients in medium-risk areas who are under surveillance.

Definition of risk zone:

1. High-risk areas: generally refers to the cumulative number of new crown cases exceeding 50, and there is a cluster epidemic within 14 days.

2. Medium-risk areas: There are new confirmed cases of new crown pneumonia within 14 days, and the total number of confirmed cases of new crown pneumonia does not exceed 50 cases; A total of more than 50 confirmed cases have been confirmed, and there have been no clusters of outbreaks in the past 14 days.

3. Low-risk areas: There are no confirmed cases of new crown pneumonia, or no new confirmed cases for 14 consecutive days.

Criteria for Division:

1. Region: Take streets and towns as the basic units.

3. Epidemic situation: the total number of new crown pneumonia cases and whether there is a cluster epidemic.

Response strategies: 1. High-risk areas should implement the strategy of internal prevention of proliferation, external prevention of export, and strict control, and continue to make every effort to do a good job in epidemic prevention and control. 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. For medium-risk areas, implement the strategy of preventing the import of foreign and internal proliferation, and restore normal life as soon as possible and in an orderly manner. Relevant organizational personnel can return to work in an orderly manner, guide the employing enterprises to strictly implement the epidemic prevention work, and at the same time promote the prevention and control of the epidemic and the resumption of work and production of enterprises.

3. For low-risk areas, implement measures to strictly prevent importation, coordinate and call for care, cancel traffic restrictions on roads and residential areas, and fully restore normal life order.

At present, the epidemic has been effectively controlled, but everyone should still reduce unnecessary outings, try to avoid high-risk areas, and spend the Chinese New Year in good health. After Shijiazhuang Xinle City was reduced to low risk, as of 9:00 on February 8, the latest data shows that there are currently 36 medium-risk areas in the country; There are 9 high-risk areas.

The risk areas are concentrated in five regions: Heilongjiang, Jilin, Hebei, Beijing and Shanghai. Medium-risk areas: There are new confirmed cases within 14 days, the cumulative number of confirmed cases does not exceed 50, or the cumulative number of confirmed cases exceeds 50, and there is no cluster outbreak within 14 days; We will implement the strategy of "preventing foreign importation and internal proliferation" and restore normal order in production and life as soon as possible.

Legal basis: Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases

Article 42: When an infectious disease breaks out or is prevalent, the local people at or above the county level shall immediately organize forces to carry out careful prevention and control in accordance with the prevention and control plan, cut off the transmission channels of the infectious disease, and when necessary, report to the people's ** at the next higher level for decision, and may take the following emergency measures and make an announcement: (1) Restrict or stop fairs, theater performances, or other activities where people gather; (2) Suspension of work, business, or classes; (3) Sealing or sealing public drinking water sources, food, and related articles contaminated by infectious disease pathogens; (4) Controlling or culling infected wildlife, livestock, or poultry; (5) Closing places that may cause the spread of infectious diseases.

Article 45 In the event of an outbreak or epidemic of an infectious disease, according to the needs of the epidemic control of the infectious disease, the local people at or above the county level have the right to urgently mobilize personnel or transfer reserve materials and temporarily requisition houses, means of transportation and related facilities and equipment within the whole country or across provinces, autonomous regions, and municipalities directly under the Central Government.

Legal analysis: The criteria for medium-risk areas are that there are new confirmed cases within 14 days, the cumulative number of confirmed cases does not exceed 50, or the cumulative number of confirmed cases exceeds 50, and there is no cluster outbreak within 14 days. The specific criterion for risk areas is whether there are confirmed cases of new crown pneumonia in a street within 14 days, and how many there are.

The specific classification criteria should also be adjusted according to the situation and changes of the epidemic. In medium-risk areas, implement the strategy of preventing the import of external and internal proliferation, restore normal production and life order as soon as possible and in an orderly manner, organize personnel to return to work in an orderly manner, guide employment enterprises to strictly implement requirements such as disinfection, ventilation, and temperature measurement, reduce personnel density, reduce personnel gathering, strengthen personnel protection, eliminate risks and hidden dangers, and achieve simultaneous progress in epidemic prevention and control and enterprise resumption of production.

Legal basis: "Basic Medical Care and Health Promotion Law of the People's Republic of China" Article 50 In the event of a natural disaster, accident disaster, public health incident, social security incident and other emergencies that seriously threaten the lives and health of the people, medical and health institutions and medical and health personnel shall obey the dispatch of the ** department and participate in health emergency response and medical treatment. For participants who cause illness, disability, or death, they are to be given relevant benefits such as work-related injuries or bereavement pensions, and martyrs' praise in accordance with regulations.

Medium-risk and high-risk areas. Low-risk areas refer to those with no confirmed cases within their administrative area, or no new confirmed cases for 14 consecutive days. Medium-risk areas refer to 14 within the administrative area

There are new confirmed cases within a few days, and the cumulative number of confirmed cases does not exceed 50; or the cumulative number of confirmed cases exceeds 50, and there has been no cluster outbreak within 14 daysHigh-wind counties refer to counties with a cumulative number of confirmed cases exceeding 50 within their administrative area, and there is a cluster outbreak within 14 days.

Extended Information: What should residents of medium- and high-risk areas be aware of?

A: First of all, we must strictly abide by the local epidemic prevention and control regulations, obey the management, actively cooperate with the implementation of epidemiological investigation, nucleic acid testing, home isolation and observation and other measures, and rule out the possibility of infection in a timely manner, so that we can rest assured and protect others.

Secondly, avoid gatherings, it is best to stay at home, do not visit the door, do not gather, do not have dinners, and do not get together. When you really need to go out, you should do a good job of personal protection scientifically, but don't overdo it, such as wearing N95 masks, wearing protective clothing, etc., hot weather may cause heat stroke, and excessive disinfection (such as spraying the whole body with disinfectant) is not necessary.

Practice good personal hygiene. Do a good job of hand hygiene, wear masks scientifically, open windows and ventilation in the room, do a good job of daily cleaning, pay attention to personal hygiene, and ensure adequate nutrition.

Don't be greedy for cold on dog days, don't let the temperature of the air conditioner be too low, and don't blow on the air conditioner. Don't stay up late at home, ensure sleep quality, and improve your own immunity.

Do a good job of health monitoring. It is recommended to measure body temperature in the morning and evening, and if you have symptoms such as fever, dry cough, fatigue, nasal congestion, runny nose, sore throat, myalgia, diarrhea, etc., contact the community management personnel to go to the fever clinic of a nearby hospital for treatment as soon as possible, wear a mask throughout the process, do not take public transportation, and keep a distance of more than one meter from others.

Another thing is to maintain a good attitude, not to be anxious and not to panic. Obtain epidemic information from the official release platform, do not believe rumors, do not spread rumors.

Due to the possible virus contamination and unknown infection in high-risk areas, the population in this area is the key target of "testing and testing", and repeated testing is required. Because the new coronavirus is characterized by a certain incubation period and insidiousness, if the concentration of the virus in the body is not enough and is below the detection limit during the first nucleic acid test, it may not be detected; In addition, different people may have different sampling methods, and failure to collect suitable parts may cause missed detection; Finally, it is possible that a small number of infected people may have interstitial detoxification, and if the sampling time is not correct, it may cause missed detection.

Therefore, in order to detect the pathogen more accurately, implement prevention and control more accurately, detect the infected population as soon as possible, cut off the chain of virus transmission, and carry out repeated testing in a timely manner.
