Per capita numbers would be much more relevant.
No, they would not. That's not how pandemics work. Population size becomes relevant when a sizable fraction of people are infected (or dead). Then the virus is starting to run out of "food" — uninfected people to spread to. In both Italy and US, <<1% infected so far.
Aren't they also useful for measuring the stress on health-care systems? X infections in the US or China is not as concentrated as X in Italy.
Disagree. 778/million people in Italy is very different than the 58/million in the US (data as of March 20). Population size correlates with size of health system that would have to absorb the influx of sick patients.
