Finally, there's a third coincidence. The Wuhan Center for Disease Control and Prevention, key to virus prevention and detection, moved its laboratory in Wuhan on December 2, 2019. The WHO report, written in conjunction with Chinese officials, notes this fact and says it could have been disruptive to a laboratory's operations. It also notes the lab moved to a location near the Huanan Seafood Market, the exotic animal trade center thought to have played a major role in the virus' early spread. The move happened just six days before the first patient experienced Covid-19 symptoms, according to China's account. (He is, the WHO report said, an accountant working for a family company, with no known history of attending crowded events, animal "wet market" contact, or exotic trips to the wilderness. These facts suggest he may have got it in the city, perhaps from another person). These three pretty huge coincidences foster the lab-leak theory, and mean it has not yet gone away. Western intelligence officials CNN has spoken to say they cannot "disprove" the idea -- or prove it. These coincidences are perhaps why it sits in this hinterland -- never permanently debunked, never proven. Their solution is like "Occam's razor" -- the idea that the simplest explanation is the most likely.
