Look at the infection rates in those countries: they're S-curves. New infections are being found, but the rate of increase is far lower than it was previously, and the majority of cases are cleared up. That shows they're likely on the tail end of the problem. For European countries and the US, the curve looks asymptotic. There's no telling how high it'll go at this point.
