First, why should we divide the closed control area, control area and prevention area?
In order to find and control the infected people in COVID-19 as soon as possible, block the transmission route of the epidemic, and effectively curb the spread and spread of the epidemic in the community, according to the risk of epidemic spread, the epidemic area is accurately divided into three areas: closed control area, control area and prevention area, and classified management measures are implemented to fully protect the life, health and safety of residents and normal life order, and to minimize the harm caused by the epidemic to people's health and life.
Second, the difference between closed control area, control area and prevention area?
The division standard of closed control area: generally refers to the residential area where cases and asymptomatic infected people live from 2 days before onset or positive detection to the area with frequent activities around them before isolation management. Can be accurately divided into communities, buildings, units and so on.
Control measures: implement "closed area, never leaving home, door magnetic management and door-to-door service", strictly implement home isolation measures, wear masks when home isolation, and minimize contact between family members. Do a good job in environmental disinfection and ventilation. Arrange 24-hour patrol duty to prevent people from going out and moving, and try to stay indoors. If the management is difficult and the risk of transmission is high, residents in this area can be transported to centralized isolation places when necessary. If you really need to go out for medical treatment, you must contact the community prevention and control office for approval, arrange a special car, do a good job of personal protection, and implement closed-loop management.
Release standard: The blockade can be released when the following conditions are met. There were no new cases or asymptomatic infections in this area in recent 14 days; The last close contact in this area has been exposed for more than 14 days, and the nucleic acid test is negative; All personnel in this area completed a round of nucleic acid screening 2 days before unsealing, and all were negative.
Criteria for dividing the control area: from 2 days before the onset of the case or 2 days before the asymptomatic infected person is tested positive to before the isolation management, if there is a certain risk of transmission to people in workplaces, activity places and other areas, but it is impossible to accurately determine whether the area is closely related or sub-closely related, then the area can be judged as a control area and can be accurately divided into communities, buildings and units. If the nucleic acid in this region is found to be positive, it will become a closed control region.
Control measures: In the control area, "No personnel are allowed to leave the area and no gathering is allowed". In principle, people can stay at home. Every two to three days, each household can arrange 1 person. Under the premise of strict personal protection, the number of people can be limited to the designated place in the community to buy daily necessities. For those who really need to go out for medical treatment, the community will issue a certificate and do a good job in auditing and registration. All personnel entering the site shall be verified, code checked, temperature measured and registered. Wear a mask at home to minimize contact between family members and disinfect and ventilate the environment. All other closed public places are closed except shopping malls, supermarkets and farmers' markets to ensure the normal living needs of residents.
Release standard: When the following conditions are met at the same time, the control can be released. There were no new cases or asymptomatic infections in this area in recent 14 days; The last close contact in this area has been exposed for more than 14 days, and the nucleic acid test is negative; Two days before deregulation, all personnel in this area completed a round of nucleic acid screening, and all the results were negative.
Criteria for the division of prevention zones: the enclosed areas in the county and the areas outside the control areas are all prevention zones.
Control measures: the prevention area implements "strengthening social control and strictly limiting the scale of personnel gathering". Strictly limit the gathering of people, and strictly implement measures such as entering indoor public places to make an appointment for peak shifting, measuring temperature, scanning codes, and wearing masks. Shopping malls, supermarkets, farmers' markets and other basic living materials supply places should reasonably control the number of personnel. Strictly control the scale of party activities such as parties and dinners. At the beginning of the epidemic and before the risk is cleared by epidemiological investigation, the business activities of Internet cafes, karaoke bars, chess rooms, libraries and other related indoor public places will be suspended. Control the business scale and business hours of restaurants and public canteens, and suspend eating when necessary. Residents should take the initiative 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, diarrhea, etc. They should take the initiative to go to a medical institution in time. Actively cooperate with the investigation of risk personnel.
Release standard: all closed control areas and control areas in the county are released.
3. Can I travel in the closed control area, control area and prevention area?
According to the corresponding control measures, the closed control area should be kept indoors, and the people in the control area should not leave the area to prevent the people in the area from traveling in an orderly manner. No special needs, without the approval of the municipal and district epidemic prevention and control departments, shall not leave the local. Residents in other parts of the city do not have to leave the local area or the province.
4. What should I pay attention to after unsealing and deregulating the controlled area?
According to the principle of "no prevention after unsealing", the residents in the sealed control area will continue to be monitored for health. In the process of health management, it is necessary to carry out "two points and one line" management of their residences and units, and do a good job of personal protection throughout the process. They should not go to public places, crowded places or take public transportation. It is recommended to do nucleic acid testing on the seventh day. Communities and units should continue to do a good job in the management of personnel entry and exit, strictly implement measures such as temperature measurement, code inspection and standard wearing of masks, and advocate non-contact delivery of take-away and express delivery. Elevators, corridors and public areas and other key places and facilities are regularly ventilated and disinfected. Implement the classified collection of domestic garbage in residential areas to achieve timely disinfection and "Nissan Nissin".
After the control area is lifted, normal epidemic prevention and control will be resumed. Residents should do a good job in personal hygiene protection when traveling, and consciously develop good hygiene habits such as wearing masks, washing hands frequently, watching meals, not getting together, and having fewer parties.
