The owner asked how to answer the main floor of the property.

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.
