The man who was still in the train after the initial screening in Putian was detained. How can epidemic prevention and control prevent this from happening?

From this perspective, we can not only see a person's legal consciousness and human morality, but also see the prevention and control efforts of a city. The positive results of nucleic acid initial screening may be virus infection, false positive results and so on. Because nucleic acid mainly detects DNA or RNA of virus gene molecules, it can generally be determined whether the detector is infected by virus. Nucleic acid is the genetic material in the capsid of RNA virus or DNA virus. If the virus nucleic acid in the patient's blood or other tissue samples is positive, it indicates that the patient has been infected by the virus.

All the close contacts of the train have been closed-loop transported to the centralized isolation point for centralized isolation medical observation. The railway department has disinfected the terminal in key areas such as G2 190 full train carriages, Loudi South Station transshipment, and entrance passages, and will handle the procedures for changing or refunding stranded passengers in the future. In the investigation of the close contacts of positive cases in other places, a case of COVID-19 virus nucleic acid was found to be positive at the initial screening, which was confirmed as positive by Fuzhou Center for Disease Control and Prevention.

There is an urgent need to find people who intersect with the trajectory of positive diagnosis. Please report to the township, village (community) and unit at the same time and in the same space, cooperate with the implementation of health management measures, conduct nucleic acid testing, and stay at home. The work headquarters of taijiang district, Fuzhou city, Fujian province reported that in the investigation of close contacts of positive cases in different places, a case of COVID-19 virus nucleic acid was found to be positive at the initial screening, which was confirmed by Fuzhou Municipal Center for Disease Control and Prevention? The comments were positive.

Knowing that he might be infected with COVID-19, he bought a ticket and left Shanghai for Putian Railway Station, which made his train closely connected with 20 1 person in other provinces and cities. In Putian, his wife Li was infected with Zhao, the driver of the online car, 10 people were in close contact, and 47 people were in close contact. The public security organs have filed a case for investigation and taken criminal compulsory measures according to law. Although it takes some time to get the results after nucleic acid detection, it also takes some time to synchronize with the health code after the results come out.
