Now the global epidemic situation is so serious that there are countless deaths, so I want to be a doctor. My brother is studying in the United States. The number of covid patients in American hospitals is rising. This largest and longest surge trend set another record on Wednesday, with more than 100000 inpatients. I'm very worried. Of course, this has something to do with the fact that they didn't pay attention to it at the beginning. If we pay enough attention to it, like China, and listen to doctors' advice, wear masks and do not gather together, we will not develop like this.
