How many days will it take for Shanghai global static management?

Static management can be lifted if there are no new cases or asymptomatic infections in the area in the past 14 days.

For more effective management during the epidemic, the epidemic areas are generally divided and managed into closed areas, control areas and prevention areas, and the standards for dividing these three areas of water areas are also strictly regulated. . What is the difference between a closed and controlled area and a prevention area? Below, we will give you a detailed comparison and introduction through the classification standards and closure conditions of the closed and controlled areas and prevention zones.

1. Differences between sealed and controlled areas, control areas and prevention areas

1. Sealed and controlled areas

Dividing criteria:

Case and The communities where asymptomatic infected persons live and the surrounding areas with frequent activities can be classified as containment areas.

From 2 days before the onset of the case or 2 days before the positive test of the asymptomatic infection to the isolation management, if it has a high possibility of spreading to people in the workplace, activity areas and other areas, and close contacts , it is difficult to determine the close contact tracking, and the relevant areas can also be classified as closed and controlled areas.

The closed area can be accurately divided into communities (natural village groups), buildings, units, etc., and the implementation of "area closure, stay at home, and door-to-door services."

Lifting standards: < /p>

The lockdown can be lifted when the following conditions are met at the same time:

There are no new cases or asymptomatic infections in the area in the past 14 days;

The last person in the area The nucleic acid test of the close contacts who were last exposed for more than 14 days was negative;

All personnel in the area completed a round of nucleic acid screening 2 days before the unblocking, and all were negative.

2. Control area

Division criteria:

From 2 days before the onset of the case or 2 days before the positive test of the asymptomatic infection to the isolation management, such as the work place, activity place, etc. People in the area have a certain risk of transmission, and it is difficult to determine their close contacts and close contacts. The relevant areas are classified as control areas.

The control areas can be accurately divided into communities (natural village groups) and buildings. Buildings, units, etc. are subject to "no people leaving the area and gathering is strictly prohibited"

Those who test positive for nucleic acid in the control area will be immediately transferred to the closed control area

Lifting criteria:

p>

The lockdown can be lifted when the following conditions are met at the same time:

There are no new cases or asymptomatic infections in the area in the past 14 days;

The last person in the area The nucleic acid test of close contacts was negative for more than 14 days since the last exposure;

All personnel in the area completed a round of nucleic acid screening 2 days before the release of the control, and all were negative

3. , Prevention areas

Dividing standards:

The areas outside the closed and controlled areas in the county (district) are all prevention areas.

The implementation of "strengthening society". Face-to-face control and strict restrictions on gatherings of people.
