What's the difference between closure and closure?

There are differences between the two concepts: closed area is the work and living place of positive testers and high-frequency activities, and closed control refers to the activity tracks of positive testers and close contacts, which should be defined according to risk assessment.

what are the sealing and control measures for high schools and low-risk areas?

in the high-risk area

take the measures of sealing and controlling: staying at home and providing on-site service. There were no new infections in the area for 7 consecutive days, and all the people in the risk area were negative after completing a round of nucleic acid screening on the 7 th day, which was reduced to a medium risk area; For three consecutive days, no new infections were reduced to a low-risk area.

in the middle risk area

take sealing and control measures: stay out of the area and take things at the wrong peak. There were no new infections in the area for 7 consecutive days, and all the people in the risk area were negative after completing a round of nucleic acid screening on the 7 th day, which was reduced to a low-risk area.

in low-risk areas

measures shall be taken to seal off and control: personal protection and avoidance of aggregation. People in the area who leave Haikou City must hold a 48-hour negative nucleic acid test certificate. After all the medium and high risk areas are removed, the low risk areas will be adjusted to normal prevention and control.

which is more serious, the closed area or the control area?

The sealed-off area is more serious than the controlled area. The sealed-off area refers to the residential area where cases and asymptomatic infected people live and its surrounding areas with frequent activities. The control area refers to the two days before the onset of the case or the two days before the asymptomatic infected person is tested positive to the isolation management, and it is difficult to determine the tracking work.

differentiated management of sealed control area and controlled area

sealed control area is from 2 days before the onset of the case or 2 days before the asymptomatic infected person is tested positive to the isolation management. For example, it is more likely to spread to people in its workplace, activity area and other areas, and it is difficult to judge the contact and close contact, and the relevant areas can also be classified as sealed control areas.

The control area can be accurately divided into communities (natural village groups), buildings, units, etc. People are not allowed to leave the area, and gathering is strictly prohibited. Anyone found negative in the control area can be immediately turned into a sealed control area.

the closed control area can be accurately divided into communities (natural village groups), buildings, units, etc., and "the area is closed, and services are provided at home". Only if there are no new cases or asymptomatic infections in the area in the last 14 days or the last close contact in the area has been exposed for more than 14 days, the nucleic acid can be released if it is negative. A round of nucleic acid screening should be completed for all personnel in the area 2 days before the release of control, and all of them were negative.

Legal basis: Article 45 of the Law of the People's Republic of China on the Prevention and Control of Infectious Diseases, when an infectious disease breaks out and is prevalent, the State Council has the right to mobilize personnel or reserve materials within its administrative area, and to temporarily requisition houses, vehicles and related facilities and equipment nationwide or across provinces, autonomous regions and municipalities directly under the Central Government.
