美国某位医生在社交媒体今天发表的看法:This is my theory: The virus is already everywhere. Only the most severe cases end up at the medical centers, and those are the ones that get tested. The death rate is taken from that sample. But for the vast majority of cases, this presents as a fever/cough/flu like thing, and for that, most people do not go to the doctor. I know lots of people with a cough/fever thing right now. Wouldn't surprise me if this was the Coronavirus. I bet when it's all said and done, the death rate is considerably lower than we currently think it is.
