What's the difference between a closed area and a controlled area?

Difference between enclosed area and control area:

I. Definition:

Closed (closed) area refers to the designated middle and high risk area and the discovery point, residence point, work point, activity point and surrounding area of positive cases. Control area refers to the residence, work place, activity place and its surrounding area of close contacts, sub-close contacts and people with high exposure risk of positive cases.

Second, the control measures:

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. Prevention and control measures such as "people don't leave the area, people don't get together" are implemented in the control area, and all personnel entering and leaving the area are subject to verification, code checking, temperature measurement, registration and 48-hour nucleic acid test report.

Three. Conditions for dissolution:

When the following conditions are met at the same time, the blockade of the blockade area and the control area can be lifted:

(1) There were no new cases or asymptomatic infections in this area in recent 14 days;

(2) The last close contact in this area was exposed for more than 14 days, and the nucleic acid test was negative;

(3) All personnel in the area completed a round of nucleic acid screening 2 days before the control was released, and all were negative.

Fourth, the management mechanism:

If new infections are found in the control area and prevention area, it will be upgraded to closed area management. If there are no new infections in the control area within 7 days, the control will be released and transferred to the prevention area for 7 days.

Verb (short for verb) Travel policy:

Personnel in the announced closed control, control and prevention areas shall not leave the local area without the approval of the epidemic prevention and control department of the city or district (county). Residents in other parts of the city do not have to leave the local area or the province.
