What do you mean, security zone?
The prevention area refers to the activity area of key people who may be exposed outside the closed area and the control area, in which the prevention area requires not to go out unless necessary, and the prevention area will take two points and one line to go back and forth to the destination, and the 48-hour effective nucleic acid test proves that it is necessary to leave.
The prevention zone should also strictly implement social prevention and control measures such as the closure of closed business premises, the restriction of passengers by public transport, the restriction of flow in public places such as supermarkets and farmers' markets, and the prohibition of eating in restaurants; In terms of nucleic acid detection, the first round of all-round nucleic acid screening was started within 24 hours in the prevention area, and the subsequent detection time was comprehensively judged according to the progress of the epidemic.
Is the security area free to enter and leave?
In principle, people in the prevention area are not allowed to enter or leave unless necessary. If it is really necessary to enter or leave the country for medical treatment or specific official duties, you must hold a negative certificate of nucleic acid test within 48 hours before you can enter or leave the prevention area. In addition, people in the prevention area will be prohibited from gathering. For example, public places in the prevention area will be closed, restaurants, public canteens and other places will limit the number of people and business hours, and other places also need to implement protective measures such as temperature measurement, plain code and wearing masks.
How long does it usually take to lift the blockade of the warning zone?
At least 14 days. According to the relevant regulations of the epidemic situation, the prevention area needs to be lifted until the closed control area and the control area are all unsealed, and the nucleic acid test is negative for 14 days. Therefore, the prevention area needs to be protected for at least 14 days, but the specific number of days depends on whether there are new cases in the sealed control area and the control area and the nucleic acid detection results of all personnel. If the nucleic acid test in the prevention area is positive, it will be upgraded to a closed control area for management.
The difference between closed control area, control area and prevention area
The meaning of closed area:
The criteria for dividing the closed control area are the residential areas where cases and asymptomatic infected people live and the surrounding areas with frequent activities, and the area is closed and door-to-door service is implemented.
The meaning of control area:
The standard of dividing the control area is from 2 days before the onset of the case or the positive test of asymptomatic infected persons to 2 days before the isolation management. If there is a certain spread risk to people in workplaces, activity places and other areas, and it is difficult to judge close contacts and sub-close contacts, the relevant areas can be divided into control areas, and it is forbidden for people to leave the area and gather.
