That was a neat graph. Did you see that the death rate per case in Canada (7%) is quite a bit higher than the USA (3%)? I'm not sure why, but that could be use as evidence that public health systems don't work well.
Anyways, there is going to be lots of analyses over the next decade.
I still put Canada and USA in the same general category. We are managing Covid better than the USA. At least our national / provincial politicians are not fighting (in public anyways). That might speak to the fact that provinces in Canada (as I am coming to realize) have more control than states in the USA.
As for South Korea, that is a culture with a total different mindset. They are more ready to accept government directives than we are.
Can you imagine if Mr. Trump or Mr. Trudeau said in mid-January: "We are going to ban all flights from Asia"? There's no way we could have done the right thing at the right time.
