More than 500 people from China Communication University have been transported and quarantined. The epidemic in this school was brought in by students returning from other provinces. Although these students did nucleic acid testing on time after returning to school, the virus was latent for a long time and could not be found in time when doing nucleic acid testing. It was not until he participated in routine nucleic acid testing that he was found to have a loop. After being positive, he was diagnosed as asymptomatic infected person, and then the close crowd he contacted was controlled and isolated, and many positive infected people were found in the dense crowd.

After the emergence of positive infection in Communication University of China, strict control has been carried out and measures have been taken to close the school. However, the number of positive cases has been increasing, resulting in the need for collective transport and centralized isolation of many students in this school. In particular, there are more than 480 students in Building 36 where students related to the epidemic are located, and all of them need to be transferred to isolation points for centralized isolation. With the support of local authorities, all these students were transported and diagnosed in the early morning of September 10, and the students were sent to the designated place.

The positive infection in Communication University of China is a cluster epidemic, which was brought in by returned students from other provinces. Only this student did a nucleic acid test when he returned to school, and failed to find fever in time after entering school. Through nucleic acid test, he was diagnosed as COVID-19 positive. The epidemic also sounded the alarm for the prevention and control of the epidemic. In fact, there are not only cluster cases in Beijing, but also confirmed cases in many schools, so it is necessary to strengthen the prevention and control of epidemic situation in schools.

Schools are the key areas for epidemic prevention and control, especially universities. Their students come back to school from all over the country, and they have to do nucleic acid testing and strict health monitoring. After returning to school, it is best to concentrate on isolation or point-to-point closed-loop management to prevent foreign viruses from entering the campus, prevent the epidemic from spreading in a large area, and avoid the occurrence of cluster epidemics.
