I was referring to per capita infections and deaths, since you can't really compare the two countries using absolute numbers when the US has 7 times more people.
I see. Actually, where the number of cases is small compared to the overall population, mathematically the respective sizes of the populations are irrelevant. Given USA had 3 times as many cases on 1 March, if the exponential increase in both countries was the same, there should still be only 3 times as many in USA.
In relation to Vancouver, my guess is that it is not the number of Asians that counts, so much as how many of them travelled to Hubei province in January.
