How to divide the risk area, how to divide the risk area

Risk areas are divided into: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.

Legal analysis: Criteria for dividing risk areas: 1. Low risk, no confirmed cases or no new confirmed cases for 14 consecutive days; 2. Medium risk, 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. High risk, with a cumulative number of more than 50 cases and a cluster outbreak within 14 days.

Legal basis: Article 7 of the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases Article 7 Disease prevention and control institutions at all levels shall undertake the monitoring, epidemiological investigation, epidemic reporting and other prevention and control of infectious diseases. Medical institutions are responsible for the prevention and treatment of infectious diseases related to medical treatment and the prevention of infectious diseases in their areas of responsibility.

Under the guidance of disease prevention and control institutions, urban communities and rural grassroots medical institutions shall undertake the corresponding prevention and treatment of infectious diseases in urban communities and rural areas.

Hello, I've seen your question here.

Definition of risk area: 1. High-risk area: generally refers to the cumulative number of new crown cases exceeds 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 cases have been confirmed, and there have been no clusters in 14 days. 3. Low-risk areas:

There have been no confirmed cases of COVID-19, or no new confirmed cases for 14 consecutive days. Criteria for division: 1. Region:

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

Q: Is Shanghai a medium-risk area?

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.

Ask me if I will go back to Shenzhen on the 24th to do a nucleic acid test.

I'm in Pudong New Area, is this a medium-risk area?

Shanghai is a low-risk area, and whether to go to Shenzhen for accounting is based on Shenzhen's local epidemic prevention policy, and generally low-risk does not need to be calculated.

Thank you for your question. You're welcome.

A low-risk area is one where there are no confirmed cases, or no new confirmed cases for 14 consecutive days. Low-risk areas of the epidemic are based on counties (districts), based on comprehensive research and judgment of population and incidence, scientifically classify epidemic risk levels, have low-risk areas, medium-risk areas and high-risk areas, and clarify the prevention and control strategies of grading and classification. People from low risk do not need to be quarantined for 14 days without special symptoms.

Relevant laws and regulations: Guiding Opinions on Scientific Prevention and Precise Policies, Zoning and Grading to Do a Good Job in the Prevention and Control of the New Coronary Pneumonia Epidemic "III. Risk Delineation Criteria: With counties and districts as units, no confirmed cases or no new confirmed cases for 14 consecutive days are low-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, which is a medium-risk area; The cumulative number of cases exceeded.

50 cases, with clusters occurring within 14 days as high-risk areas.

According to the actual situation and development trend of the current epidemic, and taking into account factors such as the number of new and cumulative confirmed cases, counties and districts are divided into low-risk areas, medium-risk areas, and high-risk areas. Improve the pertinence, accuracy, scientificity and effectiveness of epidemic prevention and control through regional and categorical prevention and control, and minimize the impact of the epidemic on economic and social development and people's lives. The risk level is adjusted every 7 days.

1) Low-risk areas: Implement the strategy of "preventing foreign imports".

Strengthen the tracking and management of inflows from areas with serious epidemics and high-risk areas, and do a good job in health monitoring and services. Medical establishments have strengthened the surveillance, detection, and reporting of fever outpatient cases, and disease control institutions have promptly carried out epidemiological investigations and close contact tracing management. Supervise and guide urban and rural communities, districts, organs, enterprises, and public institutions to strictly implement community prevention and control measures, do a good job in environmental sanitation rectification, and popularize public disease prevention knowledge and protection skills.

2) Medium-risk areas: Implement the strategy of "preventing foreign importation and internal proliferation".

On the basis of taking various measures in low-risk areas, make good preparations for medical treatment, disease prevention and control, personnel, materials, and venues, and conduct isolation and medical observation and management of close contacts of cases. With school classes, building units, factory workshops, workplace offices, etc. as the smallest units, and case discovery, epidemiological investigation, and epidemic analysis as clues, reasonably determine the places and personnel for prevention and control management, and implement targeted prevention and control measures. Townships, neighborhoods, and urban and rural communities without confirmed cases may take prevention and control measures with reference to low-risk areas.

3) High-risk areas:

Implement the strategy of "internal prevention of proliferation, external prevention of export, and strict control".

On the basis of adopting various measures in medium-risk areas, stop gathering activities, and implement regional traffic control after approval in accordance with the law and procedures. At the county level, comprehensively screen for fever patients, promptly admit and manage suspected cases, confirmed cases, and asymptomatic infections, and carry out isolation and medical observation for close contacts. Disinfect relevant places in urban residential communities (rural natural villages) where community transmission or clustered epidemics have occurred, and take control measures such as restricting the gathering, entry and exit of people at banquets.

High-risk areas. 1.Criteria for division. Cases and asymptomatic infections.

Places of residence, 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.

2.Prevention and control measures. Lockdown measures were implemented, during which "stay-at-home, door-to-door service" was implemented. During the lockdown period, new infected people are found to be subject to the local joint prevention and control mechanism.

Organize and carry out risk research and judgment, and in accordance with the requirements of "one district, one policy", all or part of the original closure and control area can be extended for the closure and control time.

3.Removal criteria. There were no new infections for 7 consecutive days, and all personnel in the risk area completed a round of nucleic acid screening on the 7th day and were negative, and the area was reduced to a medium-risk area.

No new infections for 3 consecutive days have been reduced to a low-risk area.

2) Medium-risk areas.

1.Criteria for division. Areas such as workplaces and activity sites where cases and asymptomatic infected persons stay and move for a certain period of time, and may be at risk of epidemic transmission, are classified as medium-risk areas, and the scope of risk areas is delineated based on the results of epidemic investigations.

2.Prevention and control measures. During the implementation of control measures, "people do not go out of the area, and take things at staggered peaks".

3.Removal criteria. There have been no new infections in the hail shed for 7 consecutive days, and all personnel in the risk area have completed a round of nucleic acid screening on the 7th day and are negative, which will be reduced to a low-risk area.

3) Low-risk areas.

Other areas in the counties (cities, districts, banners) where medium- and high-risk areas are located are low-risk areas. Implement "personal protection and avoid gatherings", and leave the city with a 48-hour nucleic acid test negative.

Prove. After all medium and high-risk areas are lifted, normalized prevention and control measures will be implemented in the whole county (city, district, banner).

1. Low-risk areas.

There are no confirmed cases of new coronavirus, or no new confirmed cases for 14 consecutive days.

2. Medium-risk areas.

There were new confirmed cases in 14 days, and the total number of confirmed cases did not exceed 50; The total number of confirmed cases of new coronavirus pneumonia has exceeded 50, and there has been no cluster outbreak in 14 days.

3. High-risk areas.

There are more than 50 new crown cases in total, and there are clusters of outbreaks in the past 14 days.

Specific classification criteria.

1.Region: The basic unit is the sub-district and township.

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.

After all medium- and high-risk areas in the county (city, district, banner) after the outbreak of the epidemic are lifted, normalized prevention and control measures will be implemented in the whole county (city, district, banner) where the epidemic occurs. At the same time, the ninth version of the prevention and control plan also clearly stipulates that in the process of epidemic handling, if the risk of transmission of individual cases and asymptomatic infected persons to the place of residence, work and activity area is low, and the close contacts have been controlled in a timely manner, and there is no risk of community transmission after research and judgment, then the risk area can also not be demarcated. Further improve the scientificity and accuracy of epidemic prevention and control.
