Although China has always adhered to the policy of clearing the epidemic, many foreign regions have been basically in a flat state. Due to various reasons, domestic and foreign exchanges have been going on, leading some people who came back from abroad to bring the virus back to China.
Although there will be a period of isolation, there is no guarantee that there will be no problems.
Second, the spread of the virus is becoming more and more hidden.
Although researchers have done some research on viruses, they are constantly mutating. At present, the nucleic acid detection methods may not be able to find some mutant strains, but once a confirmed patient appears, it means that the virus may have been closed for some time, which brings great trouble to the anti-epidemic and epidemic prevention.
Third, epidemic prevention work in some areas is not in place.

Tianjin has carried out all-staff nucleic acid testing. Why is the epidemic always repeated?

Because the spread of the virus is becoming more and more hidden, epidemic prevention work in some areas is not in place, domestic and foreign exchanges and other reasons, the epidemic situation always appears repeatedly.
Since the outbreak of the epidemic, people's lives have been seriously affected. In the case of adhering to the policy of dynamic zero clearing, repeated outbreaks have become an obstacle to people's normal life.
Tianjin launches full-time nucleic acid testing.
The relevant departments of Tianjin issued a notice saying that due to local epidemics in many places in China, some areas grew rapidly, and positive infected people were detected in relevant regional controllers and active medical staff in fever clinics in Tianjin, and the epidemic prevention situation was very severe.
In this case, Tianjin epidemic prevention and control headquarters decided to carry out nucleic acid testing in the whole city, and requested that no one should be detected. Before the screening sampling is completed, all people living in Tianjin need to remain relatively still in their places of residence.
The reasons for the repeated rebound of the epidemic.
I. Continue to carry out domestic and international exchanges.
Although China has always adhered to the policy of clearing the epidemic, many foreign regions have been basically in a flat state. Due to various reasons, domestic and foreign exchanges have been going on, leading some people who came back from abroad to bring the virus back to China.
Although there will be a period of isolation, there is no guarantee that there will be no problems.
Second, the spread of the virus is becoming more and more hidden.
Although researchers have done some research on viruses, they are constantly mutating. At present, the nucleic acid detection methods may not be able to find some mutant strains, but once a confirmed patient appears, it means that the virus may have been closed for some time, which brings great trouble to the anti-epidemic and epidemic prevention.
Third, epidemic prevention work in some areas is not in place.
The epidemic prevention work has been carried out in an all-round way for three years, and the staff in many areas are tired of coping. Many times, it is coping, which leads to some positive patients not being found in time, which brings great trouble to the local epidemic prevention and control.
Fourth, some people have a weak awareness of epidemic prevention.
Although the relevant departments have been emphasizing the importance of epidemic prevention, some people's awareness of epidemic prevention in life is still very weak, and even they don't wear masks when traveling. Some residents don't do nucleic acid testing on time or report to the relevant units in advance even after returning to the low-risk area from the middle-high risk area.
The existence of such personnel undoubtedly brought great difficulties to the anti-epidemic and epidemic prevention work, and also led to the recurrence of epidemic situations in various regions to some extent.
