Africa has dramatically lower rates of obesity, a younger population, less asthma, less air conditioning, and as a sibling comment notes, the people get more sun exposure, hence Vitamin D.
Everything we know to track with high mortality, Africa has less of. They also have very little testing, so the infection rate is unknown and somewhat irrelevant, since few people are ending up in hospitals and dying.
High. This past winter here was one of the coldest ones in more than a decade. South Africa is also the only country in Africa(south of the Sahara) that really tests.
