This was a political panic job designed to sabotage the economy. Not that the virus isn't real; that seems undeniable. Not that it wasn't manufactured in a lab -- case not proven yet, but it seems likely. But it certainly wasn't the deadly disease it was sold as when the CDC's Dr Fauci shut down the country.
Unanswered questions: So why did China shut down like they did? Maybe deliberately, because they hate Trump and were read in on the plot. Maybe they just panicked in the presence of an unknown disease. Maybe the disease really was as bad as advertised, but mutated to a less deadly strain. Maybe air pollution in China is bad enough to increase vulnerability. I don't know.
