What do you mean by sealed control area?

The closed control area is defined as the residential area or the surrounding area where cases and asymptomatic infected people are frequently active, and the management of "closed area, home waiting for treatment and home service" is implemented.

The control area refers to the area where work and activities began two days before the onset of the case or two days before asymptomatic infected people detected positive isolation management, and the management of "people don't leave the area and people don't gather" was implemented.

The scope of the prevention zone is defined as the closed control zone and the area outside the control zone in the county (district), and the management of "strengthening social control and strictly limiting personnel gathering" is implemented.

Residents in all areas should be well protected;

Continue to do personal protection. Wash your hands frequently. Proper hand washing can wash away the virus. Wash your hands with running water and soap after eating and defecating, and after touching pets or their feces. Wash your hands for at least 20 seconds at a time.

Always ventilate. Frequently opening windows for ventilation and maintaining air circulation can reduce the density of viruses and bacteria in the air. Ventilate the room 2-3 times a day, each time for no less than 15 minutes.

Cooperate with nucleic acid detection. Residents in the control area and the prevention area should also wear masks when going out, do not gather together, keep a social distance of 1 m, observe cough etiquette, actively inoculate COVID-19 vaccine, and strengthen the "needle" strength.
