Why do overseas imports flow to provinces and are not inspected when entering the country?

They will be inspected when entering the country, and there are three lines of defense to prevent the epidemic from being imported. However, due to the long incubation period of the virus, the infected person is asymptomatic, and imported cases will inevitably appear.

China is too big, and there are too many overseas Chinese. China didn't close the door and completely stopped international flights. In addition, the virus has a long incubation period and there are asymptomatic infected people. Together, these factors will inevitably lead to imported cases.

China has built three lines of defense to prevent the epidemic from being imported. The first line of defense is before entry. In view of the three main links of overseas ticket purchase, we should grasp the dynamic information of inbound personnel in advance and conduct big data analysis after the flight takes off and before landing. The second line of defense is to set up special areas and special passages at ports to check the entry personnel from key epidemic countries and check the trajectory of overseas stay one by one. After the entry of the third line of defense, the National Immigration Bureau of China will use the information data of entry-exit personnel to inform the relevant joint prevention and control mechanism of entry-exit personnel in real time, and fully support the implementation of centralized isolation of overseas personnel and strict and accurate prevention and control management inside and outside the community. Anyone who intends to leave the country in violation of the quarantine period will be stopped and handed over to the competent department for legal treatment.
