It is necessary for universities to distribute disinfectant to every dormitory. First, talk about disinfectant. Disinfectants are used to kill pathogenic microorganisms in the medium, making them harmless and giving students a good dormitory environment. Disinfectants can destroy pathogenic microorganisms outside the human body and cut off the transmission route of infectious diseases. For example, this year's COVID-19 epidemic, disinfectants can effectively reduce the spread. Moreover, the dormitory equipped with disinfectant is a guarantee. First, freshmen are always unprepared when preparing school supplies, and forget these necessary sanitary disinfection supplies, and some disinfection supplies contain alcohol, so they are not allowed to carry vehicles because there are safety hazards when taking the train or some public transport. Therefore, every dormitory in the school should be given disinfectant, so that freshmen can wash their hands and some personal belongings to prevent virus infection. Secondly, for all college students, at the beginning of school, students from all over the world gather here by car one after another to study here. However, the spread of the COVID-19 epidemic this year has also made people's manpower, material resources and financial resources continuously lose, so it is also a heavy guarantee to equip each dormitory with disinfectant, which is responsible for students and teachers, blocking the virus infection and isolating the danger in the cradle. Therefore, first of all, we should distribute disinfectant in each dormitory, and secondly, each dormitory has its own disinfectant. On the one hand, it prevents unnecessary disputes and discordant sounds caused by borrowing from each other. On the other hand, when using disinfectant, there will always be more contact to prevent the spread of viruses caused by borrowing back and forth. Some people may think that the equipment in every dormitory is a bit wasteful, but we don't think it's because we washed our hands with disinfectant this time that the virus carried on our hands was eliminated, which is very important for our safety and health. Similarly, hand sanitizer itself is also a necessary daily necessities. But when using disinfectants, there will always be some bad phenomena. Some people waste disinfectants. This is a matter of personal quality, which needs our supervision, not whether we are equipped or not. To sum up, I think every dormitory should be equipped with disinfectant.
