CoronaVirus So far affected Rich Countries significantly higher than poor countries (Only China where it originated and Iran are exceptions).

One Theory is people in rich countries have less immunity. (Africa, India etc have better immunity since the countries are used to poor hygienic conditions since young ages and develop better immunity).

I added Per Capita income of the country to Johns Hopkins Coronavirus Resource Center Chart: https://imgur.com/bbCzab2

Edit: I see down votes. Note that Travel between Vietnam and China has been significant (similar to west) but Vietnam is not severely impacted.
