What needs to be clear is that dynamic zeroing is not zero infection, but no social communication chain. Our usual practice is to isolate the confirmed cases and asymptomatic infected persons, and at the same time, conduct multiple rounds of nucleic acid testing in the jurisdiction to find out 1 isolated case, and also isolate or control the close contacts and sub-close contacts of confirmed cases at home.
To achieve this goal, the first thing to do is regional control, delimit closed control areas and implement static management. It is very necessary to control the flow of people in some seriously infected areas. First, we should prevent dangerous people from going out and take the virus out. The second is to prevent healthy people from coming in and increase new infections. To reach this level, local governments need to have strong organizational skills, ensure the control of people's lives in the region, have fast and accurate flow regulation capabilities, and have isolation points with complete facilities and sufficient capacity.
Secondly, a sufficient amount of all-round nucleic acid detection should be carried out. The whole staff's nucleic acid detection is also a test of organizational ability. The key point is to maintain order at the scene and prevent possible group infections. In order to achieve the goal of dynamic clearing, the ability of nucleic acid detection must keep up. Only after testing, can we know whether there are new positive infections at the social level and whether there are viruses in the environment. Otherwise, the management of blockade control is meaningless.
The other is to do a good job in closed-loop management of foreign personnel and goods. When the local area is cleared, there will be new infected people. Needless to say, there will always be objects carrying viruses entering. This link is very important for realizing dynamic zero clearing. In many places, foreign tourists were quarantined for 14 days, and then monitored at home for several days, in order to prevent foreign tourists from entering.
Therefore, the most important thing for dynamic zero clearing is to control and isolate. As long as there are no new cases in the society, even if there are cases in the isolation point, it can be regarded as dynamic clearance. It is normal for close contacts of infected people to have positive reactions, so there is no need to panic. The normal prevention and control process of dynamic zero clearing is that the number of infected cases first increases, reaches a peak and then drops sharply until it increases to zero for a period of time.
