Hypothesis: Chinese Released Fast-Spreading Corona as Cover for Something Worse that Leaked Out

We see the Chinese taking draconian measures to contain this thing. We see videos of people just convulsing and dropping dead in the streets. Huge portions of their economy have been shut down. Yet, after a significant number of cases outside of China, no deaths admitted yet.

What's outside of China doesn't appear to be the same thing as what's happening inside of China.

So ... what if something highly lethal, but slower moving, escaped from Wuhan. So the Chinese, knowing there would be hell to pay, released a fast-spreading corona virus to beat whatever the hell this actually is out of the country ... to serve as cover for whatever the fuck is actually killing all these people in dramatic fashion.
