What are the differences between closed zone, control zone and preventive zone quarantine control measures? The Notice (联防联控机制综发〔2021〕92号) contains provisions on this matter.
1.Closed (sealed) area: the area is closed, stay at home, door-to-door delivery
Application Criteria: A community with sick and asymptomatic infected individuals and surrounding areas with frequent activity can be divided into closed and controlled areas. 2 days before illness onset or 2 days before a positive test for asymptomatic infection before isolation, if the likelihood of transmission to people in the workplace, work area and other places is high and it is difficult to identify close contact and trace close contact. If it is larger, the corresponding area can also be classified as a closed area.
The closed control zone can be precisely divided into communities (natural groups of villages), buildings, units, etc.
Cancellation Criteria: A block can be lifted if the following conditions are met at the same time:
(1) there have been no new cases or asymptomatic infections in the area in the past 14 days;
(2) the last case in the area was more than 14 days since the last case, the nucleic acid test was negative;
(3) all personnel in the area underwent a round of nucleic acid screening 2 days prior to opening and they were all negative.
2. Control zone: people do not leave the territory, gatherings are strictly prohibited
Classification criteria: from 2 days before the onset of the disease or 2 days before a positive test for asymptomatic infection before isolation, if the case has a certain risk of transmission to people in the workplace, in the area of activity and other areas.
The control area can be clearly divided into communities (natural groups of villages), buildings, objects, etc., and the implementation of the measures "people do not leave the area, gatherings are strictly prohibited." Those who test positive for nucleic acids in the control area are immediately transferred to the closed control area.
Cancellation Criteria: The Control Zone may be opened if the following conditions are met at the same time:
(1) There have been no new cases or asymptomatic infections in the area in the past 14 days;
(2) The last close contact in the area was exposed for more than 14 days from the last exposure and the nucleic acid test was negative;
(3) All personnel in the area underwent a round of nucleic acid screening 2 days prior to control release and all results were negative.
3. Prevention zone: Strengthen public control and strictly limit crowds
The closed and controlled areas in the county (district) and areas outside the control zone are prevention zones, and also "strengthen public control and severely limit the gathering of people."
Measures taken in the above areas.
In the closed checkpoint area, home isolation measures are strictly observed, for those who really need to go for treatment, etc., it is necessary to coordinate with the public prevention and control service, organize a special vehicle, provide security throughout the process, and implement closed loop management. cycle. Wear a mask when isolating at home, minimize contact between family members, and take measures such as environmental disinfection and home ventilation.
Essentials and health insurance.
Assign a person responsible for supplying residents with basic living supplies and efficiently carry out the work of collecting, assisting in the purchase and delivery to households. It is necessary to allocate specialized medical institutions to provide medical services to residents of the cordoned off area, to promote the establishment of a communication mechanism between the population and specialized medical institutions, and to provide services to lonely elderly people, pregnant women, and the disabled.
Control Zone: Each household will assign 1 person to purchase materials every 2-3 days.
In principle, the control zone is at home and each household can designate one person every 2-3 days to purchase life materials from a designated area in the community, subject to strict personal protection. For those who really need to travel for treatment, etc., the Department of Population Prevention and Control issues a certificate and checks and registers. All entry and exit personnel perform checks, code checks, temperature measurements and check-in. Wear masks at home, minimize contact between family members, and take measures such as environmental disinfection and home ventilation.
Essentials and health insurance. Organize convenient service points, guide residents to orderly purchase of living supplies through meetings, rush hours, etc., and effectively avoid crowds. Advocate for online shopping for residents and contactless delivery. Ensure the delivery of essential life supplies for lonely elderly, disabled and other people with reduced mobility.
The local epidemic prevention and control command should establish special medical institutions to provide medical services to the population in the control zone, promote the establishment of communities and special medical institutions to provide medical services to the population in the control zone, and promote the establishment of a docking mechanism between communities and special medical institutions to provide medical services to lonely elderly people, pregnant women.
Prevention zone: to promote not to leave the district (district) unnecessarily.
The prevention zone strictly limits the gathering of people, and strictly implements measures such as entering closed public places for seat reservations during off-peak hours, temperature measurement, code scanning, wearing masks and temperature measurement, code scanning and wearing masks in public transport.
Shopping malls, supermarkets, farmers' markets and other places where essential items are sold should reasonably control the number of customers. Businesses and institutions are promoting online work. At an early stage of the epidemic and before the epidemiological investigation has not yet ruled out the risks, the operation of closed public places such as halls, cinemas, Internet cafes, karaoke rooms, bars, billiard rooms, museums, libraries, fitness centers, educational institutions and etc. will be suspended.
