as usual all kinds of theories are out regarding what caused it, however this does not change what has to be done, wether the disease came from a bat, a mouse or an alien from Mars or an agent from another country... when you find that one of your citizens is infected with a dangerous disease he should be immediatley quarantined on day one, his family members & friends should be quarantined, use facial recognition to check who made any kind of contact with the patient & quarantine them too, investigate all the places he went to by asking & interogating him plus facial recognition, if you find out that any of those he made contact with are also infected then do the same thing with them, finaly once you reach a point where all suspects are not infected then you can say "fewh.. the crises is over".
the first case was reported in mid december last year if I'm not mistaken, why didn't they immediatley try to contain it back at that time? Xi Jinping is the president of 1.4 billion he cannot possibly watch over every single person that is why this should be the responsibilities of the local leaders, whenever a dangerous disease is reported, the local leaders should be informed on day one, officials who don't do their job should be punished with capital punishment or at least life in prison.
any one who reads my other comments would know how much I support China (the people & the government) & it's global aspirations, I'm not one of those anti-China trolls who launch veiled attacks against China under the guise of "hey I only hate the government but I love the people".
