I think it started in China. I think the evidence for it starting elsewhere in the world is actually very limited. There is some evidence but it’s not really very good. I think the explosion in the market in Wuhan was really an amplifying event. The virus had probably been circulating (in the community) for some good few weeks beforehand.
We didn't change the picture dramatically compared to what we had before. We did improve our understanding and add details.
耍猴人评价:
Dr. Dominic Dwyer 陈述了他经历的事实也表述了他的观点。前面有网友针对他的观点提出了质疑,例如“源自中国说”的数据支持在哪里,等等。本人以为,WHO这次去溯源,就是假设“源于中国”,他们希望找到切实的证据来证实/证伪这个假设,或者至少能够向前推进一步。
