Criteria for dividing risk areas

When an epidemic situation or a major health emergency occurs in the whole country, according to the actual situation and development trend of the current epidemic situation, the counties and cities are divided into low-risk, medium-risk and high-risk areas by comprehensively considering factors such as the number of newly added and accumulated confirmed cases. High-risk area: there are more than 50 cumulative cases, and a cluster epidemic occurred within 14 days.

Medium-risk area: There were newly confirmed cases within 14 days, with no more than 50 confirmed cases or more than 50 confirmed cases, and no clustering epidemic occurred within 14 days.

Low-risk area: no confirmed cases or new confirmed cases for 14 days. After grading, the state will give corresponding countermeasures according to the specific situation.

Low-risk areas: implement the strategy of "external defense and internal advancement". Strengthen the follow-up management of influxes in areas with serious epidemic situation and high-risk areas, and do a good job in health monitoring and service. Medical institutions strengthen the monitoring, discovery and reporting of fever outpatient cases, and disease control institutions timely carry out epidemiological investigations and follow-up management of close contacts. Supervise and guide urban and rural communities, organs, enterprises and institutions to strictly implement community prevention and control measures, do a good job in environmental sanitation, and popularize public disease prevention knowledge and protection skills.

Medium risk area: implement the strategy of "preventing external input and internal diffusion". On the basis of taking various measures in low-risk areas, we should make good preparations for medical treatment, personnel, materials and places related to disease prevention and control, and conduct isolated medical observation and management for close contacts of cases. Taking school classes, construction units, factory workshops and workplace offices as the smallest units, and taking case discovery, epidemiological investigation and epidemic analysis as clues, reasonably determine the prevention and control management places and personnel, and implement targeted prevention and control measures. Townships, streets and urban and rural communities without confirmed cases can take prevention and control measures with reference to low-risk areas.

High-risk areas: implement the strategy of "preventing internal proliferation, preventing external exports and strictly controlling". On the basis of taking various measures in medium-risk areas, stop gathering activities and implement regional traffic control after approval according to law and procedures. Take the county as a unit, comprehensively investigate fever patients, timely treat and manage suspected cases, confirmed cases and asymptomatic infected persons, and implement isolated medical observation on close contacts. Disinfect the relevant places in urban residential areas (rural natural villages) where community spread or cluster epidemic occurs, and take control measures such as restricting people's gathering and access.

At present, only Wuhan city in China used to be a high-risk area, most other places are low-risk areas, and a few places have appeared medium-risk areas. I hope everyone will pay attention to the latest official news, the latest news of epidemic prevention and control, and the changes in the country's medium-risk areas. Do a good job of self-protection, try not to go to medium-risk areas, reduce the probability of infection, actively cooperate with the prevention and control work of the community and relevant departments, and win the battle against the epidemic.
