I don’t see this discussed much, but this strong correlation makes me ask a lot of question about this pandemic. This is the correlation between GDP per capita and confirmed COVID cases (per million people). Confirmed cases, of course, are only a fraction of all cases.

In addition to better testing, which I think is the major driven force here, another hypothesis: richer countries are more connected via airport passengers, so the virus arrived earlier to those countries.

That's the key, the number of contacts between countries. The more contacts, the faster the epidemic will spread, and the more money there is, the more contacts there will be. But money is not a cause, but a catalyst for expansion.

Air travel is my favored hypothesis too, because it explains other patterns, such as Iran's elite being hit before the rest of that country.

Is it reasonable to excpect a second wind of cases in these countries with less international travel? It’s already internal in many of those countries, intranational travel would be a big concern?

Indeed, and we can expect some studies on the "dangers of globalisation" coming up...

And also, percentage of elderly population. In less developed countries much less number of people live that long to become the most vulnerable group (70+)
