When many schools start school, the work is very tight and the task is very heavy, which is very important for colleges and universities. Communication University has also taken measures to let students return to school in batches very early. However, when the third batch of students returned to school, there was an unexpected student infection, which triggered a cluster epidemic. It is also very worrying that many college students are infected at school. During the peak period of students returning to school, infected students can be seen all over the world. ?
And they also contacted many classmates after returning to school, so there will be a lot of close contact. However, the school is very prone to cluster epidemics, because the school is a closed place. After students enter school, it is 3: 1, dormitory, classroom and canteen. Students will attend classes in different classrooms, so they will unconsciously come into contact with other students. So once someone is infected, it will spread very fast.
This is also a reminder to other schools, and we should not be careless. Schools should kill more places to provide logistical support for teachers and students. On the way from home to school, many students may pass through many crowded places. But a little carelessness and insufficient self-protection measures will increase the chance of infection. The virus has an incubation period, and it was discovered at school that it would spread widely at this time.
