First, students come from all corners of the country, which is easy to cause cross infection.
In universities, because of China's vast territory and rich resources, many students come from all corners of the country, which is also an important reason why the school has become an exchange point. September is the school season. When students go back to school from home, they have to take various means of transportation and meet tourists and students from all over the country. So in this process, it is easy to cross infection. Although the school requires students to carry an effective nucleic acid test within 48 hours and do another nucleic acid test before entering the campus, the mutant strain is very cunning and latent, and sometimes it needs to be tested many times to make a diagnosis. Although students are safe in the local area, there is no guarantee that there is no risk of infection during the ride. Therefore, students from all corners of the country are at great risk of cross-infection when taking public transport, which also makes the school a transmission point.
Second, schools are densely populated. Once a person is diagnosed, the consequences are unimaginable.
As we all know, there are about tens of thousands of people on a university campus, and the school is a densely populated place. Once someone is diagnosed, the consequences are unimaginable. On the way back to school, if a person comes into contact with an infected person and is not found before entering the school, then there are so many people who spread contact in the school, and it is easy to have a super transmission point. This situation is very serious.
The situation that schools become communication points is really serious, so we must attach great importance to it. For students from all over the country, they need to meet tens of thousands of people on the way back to school by bus. Therefore, after students enter the campus, they must strengthen the prevention and control of epidemic situation and carry out corresponding isolation work to prevent the phenomenon of spread beyond the scope on campus.
Mutant strains are everywhere, so it is necessary to do a good job of protection in public places, and then orderly flow in line with epidemic prevention standards to reduce cross-infection and cause greater spread.
