The eradication of infectious diseases is well controlled at home, and the number of infectious diseases abroad is still rising. From neighboring countries, South Korea and India, it is rising. This shows that their control of infectious diseases is not strict, and the freedom of assembly is unrestrained, which leads to an upward trend of infectious diseases. Our country is also sounding the alarm. Although China has successful experience in controlling the release of infectious diseases, according to the changing law of infectious diseases, the possibility of counterattack still exists. The national government ordered universities to still implement closed management. This is a method with rich scientific management experience, and it is a wise decision to protect high school students in China and let them live a normal and guaranteed life. It is right to obey the government's command in all actions, which is certain.

After COVID-19 appeared, he always appeared in some unexpected form at some time, and only a few cases were found before. For example, the recently discovered propaganda box Aso staff. It was found that Dawo, a new place in Beijing, a seafood company in Dalian, and the Urumqi epidemic in Xinjiang were delayed. This infectious disease shows that even if it seems to be under control, it can make a breakthrough in a limited environment. The school is a highly crowded place, where many teachers and students live together, with small contact space, high personnel density and many MOIN seats. Once COVID-19's case appears in dormitories and classes, it has a wide range, many related personnel and great social impact. Strict management and closed management are the keys to implement school epidemic prevention and control.

After the news came, the impression of "closed management" of college students still stayed in primary and secondary schools. Therefore, the implementation of closed management in primary and secondary schools throughout the country is of great help to the study and life of primary and secondary school students. Regarding the management of college students, it seems that I have never heard of "closed management". Many college students are questioning whether colleges and universities can become primary and secondary school students after the start of school. For college students who are used to relative freedom, this is really hard to accept! More importantly, after the implementation of "closed management", the daily life of college students may be more single. Especially for students who have little or no classes.

At present, the epidemic situation in some areas of China has been lifted, but the epidemic situation in COVID-19, China will not spread widely. Even if infectious diseases occur in some areas, they will not cause widespread spread and spread. However, the epidemic prevention and production industries of infectious diseases cannot be relaxed. Foreign countries are more serious, and the number of imported cases continues to increase, which makes it more difficult to guard against the threat of imported goods. Recently, local infectious diseases in Beijing and Dalian are all related to saliva products, so we should guard against them. Therefore, as students from all over the country, it is necessary for colleges and universities to strengthen management.
