Of course there’s another lie hidden in all of that: the virus did get out into the rest of China - there were reports of it in Beijing and elsewhere before the news blackouts.
But the numbers of cases were infinitesimal to Wuhan. Also my uncle fought them in Korea, was captured on the C’hong C’hong in Nov of ‘50. He talked about the human wave attacks. There was small regard for casualties in achieving the objective. Same here.
Looks like another accidental spill, so to spek: the virus "got out" again --- got out to the rest of China.
