China has not permitted any investigation into the origins of the virus. And given the ease with which it spreads, and the fact that everyone was heads up about it in January, you'd think we'd have heard about a proliferation of cases elsewhere if it had begun elsewhere. That didn't happen. What we saw was a spread of cases in Wuhan, then in nearby China, then major cities worldwide. And as soon as it spread worldwide, China reported exactly 50% more deaths in one day [1], then stopped reporting deaths altogether. [2] [3]

Thanks. I have my Chinese friends telling me that China let investigations happen at the labs in Wuhan but the US never let such a thing happen, and so on...
