A cluster epidemic broke out in a university in Jilin. After the school discovered the incident, it did not take isolation measures and report it in time, which led to a cluster epidemic after the rapid spread of the virus. After that, the party secretary of the university was dismissed, and then the relevant departments entered the investigation and found that the disease inside the school had spread to a very serious degree, so they quickly sent medical staff to the university. After entering this university, first of all, every student has a nucleic acid test. If positive students are found, they will be sent to relevant hospitals for treatment in time. Other undiagnosed students are advised to stay in school until all college teachers and students test negative, and then let these students go home.

Schools are the most prone places to cluster epidemics, so school leaders must pay attention to the prevention and control of COVID-19 epidemic in schools. If we don't pay attention to the prevention and control of COVID-19 epidemic, a cluster epidemic is likely to occur. In addition, the mutated COVID-19 spreads very fast. If we have close contact with the confirmed patients and don't wear masks, we are likely to be infected with this kind of virus. Therefore, whether at school or at work, we must pay attention to the prevention and control of COVID-19, wash our hands frequently, have more ventilation and eat some fruits and vegetables frequently, which can help us improve our immunity.

If our children are studying in colleges and universities now, we must pay attention to telling them to protect themselves. Don't take advantage of the virus because of your negligence, because once you are infected with COVID-19 at school, it is easy for your classmates to be infected with COVID-19, and the infection rate will be very fast. Especially after attending classes or leaving the dormitory in colleges and universities, you must wear your own mask and disinfect the dormitory in time to avoid COVID-19's opportunity.
