Hot Questions and Answers on Epidemic Prevention | Minimize inconvenience, how to prevent and control more accurately?

At present, all localities are doing a good job in epidemic prevention and control. The State Council joint prevention and control mechanism press conference pointed out that it is necessary to do a good job in risk judgment and accurately determine the risk area according to the results of detection and flow adjustment. The management of closure and control should be solved quickly to reduce the inconvenience caused by the epidemic to the masses.

Focusing on the hot issues of public concern, experts of joint prevention and control mechanism in the State Council made an authoritative response.

1. Q: At present, there are many people who are "mixed positive" in nucleic acid testing. How to stipulate the isolation time and policy for negative people?

Answer: In the population with positive "10 1" nucleic acid test, if the person is confirmed to be negative after the single test, it should be judged whether it is a close contact in time, and it can be judged within 24 hours. If it is not a close contact, immediately lift the isolation.

2. Q: In order to strengthen prevention and control, can the building door be closed?

A: Not feasible. It is strictly forbidden to block the building passage with hard enclosure, and the method of "locking at once" cannot be used. If grass-roots community management personnel and residential property management personnel block safety exits, evacuation passages and fire exits, they have violated the relevant provisions of the Fire Protection Law first.

At the same time, it is not appropriate to implement "one size fits all" rigid isolation and set up roadblocks around key areas such as hospitals. According to Article 50 of the Law of People's Republic of China (PRC) on Public Security Administration Punishment, it is illegal to obstruct the passage of vehicles such as fire engines, ambulances, engineering rescue vehicles and police cars performing emergency tasks.

Beijing recently demanded that it is strictly forbidden to block fire exits, unit doors and residential doors with hard enclosures, and the temporary control time should not exceed 24 hours in principle. Zhengzhou city requires that it is strictly forbidden to lock the safe passage door and set up roadblocks during the closure. This will affect the passage of emergency vehicles, and do not implement "one size fits all" rigid isolation around the hospital. Guangzhou requires that obstacles on closed roads should be cleared or opened in time to ensure the normal passage of fire-fighting vehicles; Evacuation passages and safety exits of closed buildings should be opened in a timely and convenient manner to ensure the evacuation of personnel, and should not be closed by welding or locking, so as to keep the life passages unblocked at all times.

3. Q: There are repeated positive cases in the building. Is the closing time extended and how to implement it?

A: If there are repeated positives in the building, there is a continuous risk of community transmission. This situation does not meet the conditions for unsealing, and it may indeed extend the time of sealing control. However, as long as it meets the conditions for unsealing, it must be unsealed in time.

According to the Plan for Delineation and Control of Epidemic Risk Areas in COVID-19, in principle, the areas where infected people live, workplaces and areas with frequent activities and high risk of epidemic spread are classified as high-risk areas. High-risk areas are generally defined by units and buildings. In the case that the risk of epidemic spread is not clear or there is widespread community spread, the scope of high-risk areas can be appropriately expanded. The scope of risk areas can be dynamically adjusted according to the results of traffic investigation and judgment.

According to the plan, no new infection cases were found in the high-risk area for five consecutive days. After completing a round of nucleic acid screening on the fifth day, all the people in the risk area were negative and reduced to the low-risk area. High-risk areas that meet the conditions for unsealing should be unsealed in time.

At the same time, in the process of handling the epidemic situation, if the risk of transmission of individual cases and asymptomatic infected persons to the residence, workplace and activity area is low, and the close contacts have been controlled in time, the risk area may not be designated after judging that there is no risk of community transmission.
