Can't the community gate in the control area be sealed?

1. Division 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 designated as closed control areas. The closed control area implements "regional closure, staying at home and serving at home".

2. Termination criteria: The following conditions are met at the same time: (1) There are no new cases or asymptomatic infected persons 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) 2 days before unsealing, all personnel in the jurisdiction completed a round of nucleic acid screening, all of which were negative.

(2) Control area

1. Classification standard: from 2 days before the onset of the case or 2 days before the 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 classified as control areas. In the control area, "people are not allowed to leave the area and gathering is strictly prohibited", and those who are found to be positive for nucleic acid testing will immediately turn into a sealed control area. 2. Termination criteria: The following conditions are met at the same time: (1) There are no new cases or asymptomatic infected persons 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.

(3) Prevention area

1. Division standard: the areas outside the closed control area and the control areas within the county (district) are all prevention areas, and "strengthening social control and strictly restricting the gathering of people" shall be implemented.

2. Release standard: all closed control areas and control areas in the county (district) are released.
