On February 28, Zhang Wenhong, the leader of the Shanghai New Crown Pneumonia Medical Treatment Expert Group, said in an exclusive interview with a reporter from China News Agency, "I always insist on the exact origin of the new crown virus." Where does a virus come from? Generally speaking, there are two aspects to look at. First, when the virus appeared and where it first appeared, we must investigate the sequence of this time; second, we need to find his position on the evolutionary tree.
Aiming at "Patient Zero", Zhang Wenhong said that random guessing is irresponsible. So far, he does not believe what anyone said, only the certification. "Only recognize the results of gene sequencing that we made ourselves," Zhang Wenhong said. (Reporter: Li Pengkang Yuzhan Editor Li Jiali)
