Hello, college students have graduated from school, but there is an epidemic in their alma mater. The specific analysis depends on how long you leave school before the school will have an epidemic. However, no matter how long it takes, I suggest you put on a mask and go to the local hospital for nucleic acid testing, which can reassure yourself, and then try to isolate yourself at home and wait for the test results. If there is nothing after the test results come out, there is no problem to a great extent, but I still suggest that you avoid going to public places with heavy traffic, not only for yourself but also for others, and try to stay away from public places with heavy traffic 14 days.
