I said most of these countries likely had much less travel seeding outbreaks, but epidemiologically, all that would do, without interventions, is delay the massive outbreaks, not stop them - look at South America, where many countries didn't start having major outbreaks until well into April. South Korea, Thailand and Vietnam (its neighbor), at least, all have a lot of travel from China, so I doubt that's a differentiating factor (per capita), whereas it would be for Africa and all of those Asian countries have very high mask compliance (over 90%, which is likely the biggest reason for their low numbers).
Also, remember that many of these countries in Africa actually have experience with dreaded diseases like Ebola, so they have some systems in place to monitor for disease and death. And for all of you folks saying that African countries are somehow incapable of counting their dead, then how did we have counts of 2544, 4810, and 3986 deaths in Guinea, Liberia, and Sierra Leone, due to Ebola a few years ago?
Have they suddenly forgotten how to count deaths or did they maybe actually have effecive interventions to arrive at 65, 72, and 82 deaths from COVID so far? Sure, their testing may not be as thorough as many first world countries, but I think they can count deaths and all three of these countries are at <20 deaths/1MM, like most of their neighbors in sub-Saharan Africa. I'm sure a young average age and less mobility have helped, but many of these countries are pretty densely populated and I simply find it hard to believe so many countries could be incapable of counting their dead as others (not you) have posted.
Also, there is zero evidence that the virus has mutated into a less deadly form. Zero.
