From Wuhan, of course
Nature just doesn't go crazy. But its clear who is crazy. I read some unverified speculative report the first emergency injection readied in weeks after the reports of virus deaths in China killed 80% of injectees. The so called killer virus is more like killer injection.
In order to talk about a 'release' you'd have to know that the object exists. Have you seen this purified object, void of any other genetic material, taken directly from the fluids of a single sick human?
