Both Russia and China are lying a lot about the numbers. They're a dictatorship after all, having panic is dangerous for their rulers. The rate of recovery in China is amazing and the fact there are NO new cases is a miracle, it's almost as if they're cooking the numbers. Korea is seeing a resurgence in cases though.
As far as the map, the aggregation happens differently in the US now than elsewhere. Most countries and initially even states in the US were aggregated. Now they're splitting them up more and more if their local government does, the US has data down to zip code. Given the red circles aren't linear in size, it makes it look like the US is a terrible place but if you zoom, there's less than a handful cases in each instance. My zip code has <5 cases.
The spread and death rate in the US is actually an outlier - more people have it but fewer than 1% are dying. In Italy death rates are now at 10%. There is a difference somewhere there in healthcare methods and quality. Even the difference between CA and NY and the rest of the country is telling how well socialist healthcare is doing vs privatized healthcare.
