Many flew from China to Thailand and from there, where ever they wanted to including the US. Airport screening is mostly ineffective. For some reason our country can't manage to run many tests, while S Korea is doing much better in that regard. This genie is well out of the bottle. We won't really know how it plays out until it does, but the possibility and likelihood of a serious pandemic along the lines of the Spanish Flu does exist. With this most likely coming from the Chinese bio weapon lab and with modern travel so common it could turn out very bad. Then there are the economic impacts. Why we ever let ourselves become so dependent on Chinese manufacturing especially for a large percent of our medicines is beyond me.
