Wuhan in China has only one of those types, rendering it in analogy as a kind of "branch" which cannot exist by itself but must have grown from a "tree".

The Taiwanese physician noted that in August of 2019 the US had a flurry of lung pneumonias or similar, which the Americans blamed on 'vaping' from e-cigarettes, but which, according to the scientist, the symptoms and conditions could not be explained by e-cigarettes. He said he wrote to the US officials telling them he suspected those deaths were likely due to the coronavirus. He claims his warnings were ignored.

Immediately prior to that, the CDC totally shut down the US Military's main bio-lab at Fort Detrick, Maryland, due to an absence of safeguards against pathogen leakages, issuing a complete "cease and desist" order to the military. It was immediately after this event that the 'e-cigarette' epidemic arose.

We also had the Japanese citizens infected in September of 2019, in Hawaii, people who had never been to China, these infections occurring on US soil long before the outbreak in Wuhan but only shortly after the locking down of Fort Detrick.
