I don't think so, just remembering back to the initial outbreak of H5N1 in (iirc) 1997 in Hong Kong, when 18 people caught the disease and 6 died. And ALL, every chicken in Hong Kong, no exceptions, was killed.
I think it was likely in the wild bird population at that time, in small numbers, and that's how the initial human cases occurred-- wild birds to chickens to people. That's only a guess, but it's my best guess. Considering the Great Plague, volcanos, tsunamis, hurricanes, 1918 flu, blizzards, earthquakes, and all the other acts of nature that humans are subject to, the possibility that this is entirely natural seems most likely to me.
I cannot help thinking that if China has cooked this up to alter the demographics of the world, they've done a piss-poor job of it.
China didn't cook it up but the government and military will recognize it as a brute force that can be utilized on certain levels. The left always respects brute force as a favorite tool, it is a modus operandi for achieving their goals.
