First of all, this is very supportive, because although students have done nucleic acid testing before entering school, the whole world is shrouded in this epidemic. Although the epidemic situation in China has been effectively controlled, the environment is still unsafe. Once an infection occurs, the strong cluster infection has a great impact on students, and the mortality rate of this virus infection is very high. If there is a cluster infection on campus, it will threaten the lives of students, so the Ministry of Education will strengthen tracking.
In this environment, none of us can exist independently without the environment. The spread of this virus is very fast, sweeping the world in just a few months, and the number of infected people in other countries is still growing at a high speed. Therefore, we must not take this epidemic lightly, especially in schools. Students are the flowers of the motherland and the backbone of the future of the motherland. Every student is the driving force of parents' life. Once the epidemic prevention and control is relaxed, it will be very dangerous for students and will collapse for parents. Moreover, schools are densely populated places. Now many students are forced to stay because of the epidemic. If you stay, it means that many people will live together, so the possibility of cross-infection is also very high.
Therefore, in this big environment, China's Ministry of Education will strengthen the tracking and prevention of the campus epidemic. Under the tracking and prevention, this epidemic will not appear on campus to protect the safety of students.
