Almost no country took it seriously enough. There is an exception, which we'll come to in a moment...
Sure, at the beginning. But it's not the same if they didn't take it seriously after China, or after China, Italy, Spain...
It's somewhat understandable that Italy didn't take it seriously after receiving cryptic reports from China. But WTF the rest of the world didn't take it seriously after Italy?
How stupid you must be to think that this shitty virus will need a visa for your country...
No idea what your problem is. I'm saying that South Korea flattened the curve very impressively, due to their recent previous experience with MERS. If you disagree, fine.
Also I'm pretty sure that the virus doesn't need a visa to enter a country - that was your idea.
Some other countries are certainly acting quickly
now, as they have the example of what can happen with Italy (also Spain). Of course it's a bit too late. South Korea was
before Italy, and didn't have the benefit of seeing what
could happen, which for me makes their response even more commendable.
