I believe that the coronavirus has an animal origin. It was first transmitted to humans in Wuhan, China, in November or December 2019. I believe that the Chinese then covered it up for a duration prior to announcing it to the world.
As a result of China's keeping certain animals and humans in close proximity and of humans eating those animals, the virus spread to humans in China and then throughout the world.
What are the prospects of a lawsuit by the non-Chinese world, charging China for our damages resulting from their negligence?
Whenever you bring a lawsuit, you are basically designating someone to be responsible for preventing something similar from happening again in the future.
So if you could sue the Chinese government for not having prevented coronavirus, it would put the government in a position of trying to control future pandemics. Do you really want the Chinese government stepping up its control paradigm?
Now the question is what if the disease was manufactured by secret genetic engineering and released via a long supply chain of terrorist networks so that it's not traceable back to its actual origin?
Then you have the problem that someone might have engineered the virus for the sake of political-economic manipulation; and any government or whomever you hold accountable for not preventing it from happening was never actually in a position to stop the terrorists who did it.
If that is the case, then the only question becomes what the goal was in engineering and releasing the virus, and how to respond. E.g. when terrorists take hostages for ransom, do you pay the ransom or just hold the hostage-takers accountable for whatever they do?
When you pay ransom, it encourages future hostage-taking, i.e. because there is a precedent set for hostage-taking as a successful business strategy.
So basically all we can do is social-distance and hope that whoever is responsible for the virus won't do it again.
I don't know if stopping these 'wet markets,' whatever they are, would ultimately solve the problem if the virus naturally emerged from them, because if they are a cultural tradition that's been going on forever, why would they suddenly begin generating pandemic viruses now and not in the past?
