I saw this statement by Chinese in January when they first made it. At the time, there were only a few hundred cases in China and some outside of Wuhan. It didn't make sense then and it doesn't now. They were also saying that the disease originated in a wet (live animal) market. Were they saying that all of those hundreds were exposed to the exact same live animal(s) in Wuhan? How else would it spread to hundreds of people except by human-to-human transfer?
