Is it the vitamin D? We should really try to figure out why these regions have done so well and try to replicate that in Europe and NA.
can provide more sources if requested (or just google it)...
Latin America seems to be all over the list of top deaths/capita for the whole pandemic, but currently the worst places (per capita deaths in the last 7 days) seems to be mostly central/eastern europe, though Argentina is pretty high in both all time and recent deaths/capita.
Where Africa is doing well or just doesn't have good surveillance to even identify cases, I couldn't say. But if a place doesn't have much inbound tourism, doesn't have lots of people able to afford international travel, and doesn't have the kind of internal mobility common in the developed world, it would make sense that they might not get hit very hard without taking much in the way of special precautions.
