Although the risk is low, the epidemic is easy to recur, and many universities will close their schools in order to avoid cluster infection and the safety of students.

From the perspective of colleges and universities, it is difficult to do a good job of specific management and recording by letting people in and out at will. Once there are people who carry the virus, they can't be found immediately, which will put the whole campus in crisis.

Although the epidemic control work is progressing smoothly, it has not been eradicated after all, and the epidemic situation has been repeated in some areas. The school's move is also for the sake of the students. The starting point is to ensure the health of thousands of students.

Precautions for university suspension:

1, pay attention to hand hygiene. In COVID-19, the important route of infection is contact transmission, especially the hands that may carry the virus should not touch the eyes, mouth and nose. Use alcohol-based hand sanitizer, tap water or hand sanitizer when washing hands.

2, do a good job in the classroom window ventilation, 3-4 times a day, each time for 20-30 minutes. Physical education class needs to open all the classroom windows when he is not in class.

3. Eat lunch separately, pay attention to wash your hands before and after meals, and don't get together to talk to avoid the spread of the virus.
