★ Seal the control area
Classification criteria:
The residential areas where cases and asymptomatic infected people live and the surrounding areas with frequent activities can be divided into closed control areas.
From 2 days before the onset of the case or 2 days before the asymptomatic infected person is tested positive to isolation management, if it is possible to spread to people in workplaces, activity places and other areas, and it is difficult to judge close contacts and close contacts, the relevant areas can also be divided into closed control areas.
Control measures:
The closed control area implements "regional closure, home stay and home service".
Send yellow code to residents, strictly implement home isolation measures, arrange 24-hour patrol duty, prevent people from going out and walking, and do not leave the house or the car, and deliver necessary living materials to the door.
If you really need to go out for medical treatment, you must issue a certificate by the community, review and register, arrange a special car, provide personal protection throughout the whole process, and implement closed-loop management.
All personnel in the blockade area "can only enter and leave, and gathering is strictly prohibited". During the closed period of 1, 4 and 7 days, all personnel were tested for nucleic acid.
Termination criteria:
When the following conditions are met at the same time, the blockade can be lifted:
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.
★ Control area
Classification criteria:
From 2 days before the onset of the case or 2 days before the asymptomatic infected person is tested positive to isolation management, if there is a certain risk of transmission to people in workplaces, activity places and other areas, and it is difficult to judge close contacts and close contacts, the relevant areas will be divided into control areas.
Control measures:
Prevention and control measures such as "people don't leave the area, people don't get together" are implemented in the control area.
In principle, the control area stays at home, and each household can arrange 1 person to buy daily necessities at the designated place in the community by region, time and place under the premise of strict personal protection.
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 entry-exit personnel must carry out verification, code inspection, temperature measurement, registration and 48-hour nucleic acid test report. Wear a mask at home, try to reduce the contact between family members, and take measures such as environmental disinfection and indoor ventilation.
All other closed public places are closed except shopping malls, supermarkets and farmers' markets to ensure the normal living needs of residents.
If the nucleic acid test of the control area is positive, it will immediately turn into a sealed control area.
Termination criteria:
Control can be released when the following conditions are met at the same time:
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.
★ Prevention area
Classification criteria:
The closed control area of the county and the areas outside the control area are all prevention areas.
Control measures:
The prevention area implements "strengthening social control and strictly limiting the scale of personnel gathering".
Strictly limit the gathering of people, strictly implement measures such as entering indoor public places to make an appointment for peak shift, measuring temperature, scanning code, wearing masks, etc., delimit shopping areas, limit shopping time, and go out at peak shift.
Shopping malls, supermarkets and farmers' markets in the prevention area restrict passenger flow, restaurants are forbidden to eat in the hall, and other entertainment closed places are closed.
Termination criteria:
All closed control areas and control areas in the county are all unblocked.
