The study that forms the basis of the claim is an interesting read. Would be good to read a scientific rebuttal to the report, as the Post article comments on some scientific dissent on its findings. It seems highly likely to me that the form of the virus that took a foothold in Wuhan, originated in China, but with current travel and trade patterns, its also not impossible that there were two epicentres. Im unsure as to whether the Italian outbreak can be genetically traced to Wuhan, but I do recall the case of a superspreader in the Alps who had recently returned from Singapore as one of the early introductions into Europe.
