① Tuberculosis is highly contagious. Tuberculosis is an infectious disease, which is highly contagious. If someone is infected, he may not get sick, but when the immunity of the infected person decreases, he can show a sick state, and the saliva of the infected person can spread. Once pulmonary tuberculosis patients appear in the campus, they can occur in a large area if they are not found in time, because the campus is a place with high student density, where students usually live and study, and the closed classroom and dormitory space will accelerate the infection rate. Therefore, it is necessary to put an end to tuberculosis patients outside the campus, so more students should be screened.
(2) the difficulty of investigation. Once the relevant personnel are found to have symptoms of tuberculosis infection, they should be immediately isolated, well protected, and go to the infectious disease hospital for examination. After the diagnosis, the teachers and students in the whole park should be investigated immediately. At this time, people who are in close contact with infected people will be examined in the laboratory immediately. This survey is very difficult, because it is very possible to contact the school collectively, and the survey is very difficult.
(3) Slow down the teaching progress According to the regulations, if there is a large-scale tuberculosis epidemic, the whole park will be closed for at least 2 weeks, which will inevitably affect a large number of people, especially the grades facing further studies. Two weeks' isolation will cause some unconscious students' grades to plummet. However, life is more important at this time.
Tuberculosis is a treatable infectious disease. If you get it, don't run away. Timely medical treatment and active treatment will definitely heal.
