We never hear about African nations. Probably because they hand out ivermectin and hcq like candy.
The Africa evidence is suppressed.
The northern and southern countries are no-ivermectin. The central, tropical countries are as you note, routine ivermectine.
There are covid stats for all the countries.
The reported per capita death rate from Covid-19 in Africa is about one-tenth of that in Europe and North America. I don’t know if that’s because of the younger population, or the warmer, sunnier climate, or the medication they take, or inadequate testing, or something else entirely, but it is significant and needs to be explained, as it could help the rest of the world.
And cancer rates are lower in these areas.
