Going back to Italy, I imagine we have a few advantages:
-Lower population density, less public transit use
-less international tourism in much of the country
-Time to prepare hospitals for a spike in patients (it won't be enough, but it'll help)
I'd bet our higher rate of obesity and associated ailments that might offset our slightly younger population though
I don't know if we have any advantages over China - they knew less about the virus since it started there but obviously they can more effectively lock things down and were better prepared for outbreaks in general because of past outbreaks.
