What is a high-risk area?
1. division standard. In principle, the living places of infected people, as well as areas with frequent personnel activities and high risk of epidemic spread, such as workplaces and activity places, are listed as high-risk areas. High-risk areas are generally defined by units and buildings. In the case that the risk of epidemic spread is not clear or there is widespread community spread, the scope of high-risk areas can be appropriately expanded. The scope of risk areas can be dynamically adjusted according to the results of traffic investigation and judgment.
2. Prevention and control measures. Implement closed control measures, during which "stay at home and provide on-site service". If new infected persons are found during the containment period, the local joint prevention and control mechanism will organize risk judgment, and the containment time of the original containment area can be extended in whole or in part according to the requirements of "one area, one policy".
3. Raise the flag. No new infection cases were found in the high-risk area for five consecutive days. On the fifth day, all the people in the high-risk area were negative after completing a round of nucleic acid screening, and they were reduced to low-risk areas. High-risk areas that meet the conditions for unsealing should be unsealed in time.
What is a low-risk area?
Other areas in the county where the high-risk area is located are designated as low-risk areas. Implement "personal protection to avoid aggregation" and leave the city with a negative nucleic acid test certificate within 48 hours.
After all high-risk areas are removed, the county will implement normalized prevention and control measures.
What are the main considerations in delineating risk areas?
1. Living conditions, living environment and natural barriers around the residence of cases and asymptomatic infected persons.
2. Crowd protection, crowd gathering, contact frequency of cases and asymptomatic infected persons with other people in relevant areas.
3 cases and asymptomatic infected people's work and activities time and scope, as well as the sealing and ventilation of related places.
4. The time interval after the discovery of the epidemic began to investigate.
Under what circumstances are confirmed cases and asymptomatic infected persons not included in the risk area determination?
1. The confirmed cases and asymptomatic infected persons found during centralized isolation medical observation, after investigation and evaluation, there is no risk of transmission outside the centralized isolation point.
2. The confirmed cases and asymptomatic infected persons found in the observation of home isolation medicine have no risk of transmission outside the home after investigation and evaluation.
3. The confirmed cases and asymptomatic infected persons found in the process of strict closed-loop management of employees in high-risk positions have no risk of personnel transmission outside the closed-loop after investigation and evaluation.
4. After discharge, those who are positive for nucleic acid detection have no risk of transmission after investigation and evaluation.
5. the Ct value of nucleic acid detection is ≥35, and it has been screened as a previously infected entry person.
What are the community prevention and control measures in high-risk areas?
1. area closed. Arrange 24-hour patrol duty, and strengthen management by installing monitoring equipment and electronic door magnetism. , to prevent people from going out and flowing, strictly stay indoors. If it is really necessary to go out for medical treatment, the community prevention and control office must coordinate and arrange, implement special vehicles to provide personal protection, and implement closed-loop management.
If the high-incidence area is located in the urban-rural fringe or rural areas, residents in this area can be transported to centralized isolation places because of insufficient sanitary conditions, difficult management and high risk of transmission. At home, take measures such as environmental disinfection and room ventilation.
2. Publicity and guidance. Timely release information and related arrangements through WeChat, SMS, WeChat official account, small speaker, a letter, etc. Guide residents to implement the requirements of personal protection and room ventilation. Pay close attention to and respond to residents' demands in time to create a good atmosphere for prevention and control.
3. Personnel contact platoon. Through door-to-door visits, establishing WeChat groups, and checking the information of water meters and meters, we can find out the base number of all people in high-risk areas as soon as possible, and timely grasp the situation of elderly people living alone, minors, pregnant women, disabled people, people with mobility difficulties, hemodialysis patients, mental disorders, chronic diseases and other people. Keep abreast of the situation of isolated personnel who have not been transferred, implement special personnel management and strict control, and strictly implement prevention and control measures such as hospitalization observation, door-to-door sampling, and health monitoring before transfer.
4. Health monitoring. Health monitoring shall be carried out for all personnel in high-risk areas, and the daily zero report system shall be implemented. Conduct 1 temperature test and symptom inquiry every morning and afternoon, understand the use of antipyretic, cough and cold, antibiotics, antiviral and other drugs by all personnel, and fill in the "Top Ten Symptoms" health monitoring registration form. If fever, dry cough, fatigue, sore throat, hypoesthesia, nasal congestion, runny nose, conjunctivitis, myalgia, diarrhea and other symptoms are found, the health monitoring group will immediately report and arrange home nucleic acid testing.
5. Nucleic acid detection. After the closure control was implemented, three consecutive tests were carried out in the first three days, 1 and two full-time nucleic acid tests were completed on the third day, and 1 antigen tests were carried out on the second day. The frequency of subsequent tests can be determined according to the test results; Within 24 hours before deregulation, 65438 0 nucleic acid tests should be completed. When conducting nucleic acid detection, it is necessary to set up sampling points reasonably and use them after being evaluated by professionals; Scientifically determine the route, strengthen on-site organization and management, implement special guidance, time-sharing and zoning, and fix the route, and urge personal protection to prevent cross-infection. For buildings and courtyards where positive infected people have been found, antigen testing can be carried out first, and then nucleic acid testing can be carried out in an orderly manner after negative. Special personnel, such as risk personnel who have not been transported, those who are positive for antigen detection and nucleic acid mixing tubes, patients with mobility difficulties, and the elderly, should take samples at home and carry out single sampling and single inspection.
6. Personnel transfer. If the personnel in the high-risk area are judged as close contacts, they will be transported to the centralized isolation place within 8 hours. Those who are found to be positive for nucleic acid test will be transported to the designated medical institution within 2 hours. Relevant personnel should strengthen local control before transshipment, and strengthen the personal protection of transshipment personnel and staff during transshipment.
7. Environmental disinfection and monitoring. Strengthen the disinfection of key areas and key parts, and disinfect key areas such as van elevators and key parts such as elevator buttons, stair handrails and unit door handles that people frequently contact. Timely carry out terminal disinfection, and evaluate the disinfection effect of cases and asymptomatic infected people in places such as residence, work and activities. Strengthen disinfection personnel training, technical guidance and supervision and evaluation.
8. Garbage sorting and removal. Standardize the setting of temporary collection points for domestic waste and medical waste. The garbage generated by those with positive nucleic acid test and the protective articles used by close contacts and staff shall be treated with reference to medical waste. Other garbage can be treated as "other related domestic garbage" according to the requirements of "disinfection first and double bagging" after unified collection, so as to achieve "daily cleaning" and keep the environment clean and hygienic.
9. Living materials and medical security. Deploy forces, make it clear that the special group is responsible for the supply of basic living materials for residents, and do a good job in collecting demand to help purchase and deliver goods to households. The local epidemic prevention and control headquarters should coordinate the development and reform, commerce, public security, transportation and other departments, smooth the transportation channels, promote the security of supply units and large supermarkets to strengthen docking with the community, and timely distribute related materials; It is necessary to designate specialized medical institutions to provide medical services for residents in high-risk areas, promote the establishment of a docking mechanism between communities and specialized medical institutions, and provide medical convenience for elderly people living alone, minors, pregnant women, disabled people, people with mobility difficulties, hemodialysis patients, mental disorders and patients with chronic diseases.
10. Psychological assistance and social work services. Inform people in high-risk areas of the telephone number of psychological assistance hotline, provide psychological support, psychological counseling and other services, alleviate negative emotions, prevent and alleviate psychological distress caused by the epidemic, and prevent extreme events caused by psychological pressure. When people in high-risk areas are found to have mental health problems, they will be referred to the corresponding mental health medical institutions in time.
What are the community prevention and control measures in low-risk areas?
1. Strengthen social control. All kinds of personnel in the jurisdiction shall carry out nucleic acid testing as required, and try to reduce going out, not gathering and not getting together during the period, and do personal protection when going out; Strictly implement measures such as entering indoor public places to make an appointment, shifting peaks, limiting current, measuring temperature, registering and wearing masks.
2. Personnel investigation and control. After receiving the information on the investigation of overflow personnel in high-risk areas, the investigation of risk personnel should be completed within 24 hours, and personnel management, health monitoring, nucleic acid detection, personnel transfer and other work should be coordinated; For those who cannot be investigated, timely feedback should be given to form a closed loop of investigation.
3. Traffic control. People in low-risk areas advocate that it is not necessary to leave the area, and cross-city mobility must have a negative nucleic acid test certificate within 48 hours. Transportation of production, living and medical protection materials and vehicles and personnel engaged in "point-to-point" transshipment of road transportation should be ensured on the basis of strict implementation of various prevention and control measures such as disinfection and closed management. Strengthen the control of traffic checkpoints in railway stations, airports, highways, waterways and other entry and exit areas, and do a good job in temperature measurement, verification and code inspection.
4. Nucleic acid detection. According to the risk assessment results of epidemic spread and the management of risk personnel, scientifically determine the population range and frequency of nucleic acid testing in low-risk areas. When nucleic acid detection is carried out, sampling points will be set nearby and will be activated after evaluation by professionals; Strengthen on-site organization and management, carry out in an orderly manner, avoid gathering, and urge personal protection.
5. Health education. Strengthen health education, remind residents to reduce going out, avoid gathering, keep social distance and do personal protection. After symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell, stuffy nose, runny nose, conjunctivitis, myalgia and diarrhea appear, you should take the initiative to see a doctor in a medical institution in time. Do a good job in propaganda and guidance of prevention and control policies, so that residents can actively cooperate with the investigation of risk personnel.
