Yes, I suggested countries because thats easy. But in large countries like China and the US, there are sub-populations that have their own characteristics. The cities of the northwest of China are different than the cities of the southeast. As Seattle has little to do with a city like St. Louis. Anyway the overall curve could be flattening. But that is a composite of the micro populations that make up the worlds population. And no behavior or government tactic can be said to be effective or useless, because each is applied to a different population.

China now has 12 provinces that are reported to be completely disease free. That is progress.
