There's a difference between a government not doing anything/much and the people not doing anything. I've been monitoring Sweden and Brazil because both governments have been pretty lax. As of the latest statistics I can find, Sweden has suffered about 79 deaths per million and Brazil 4 per million (US is currently 45/million and the hard hit European countries are between 100 and 300, with Spain the worst at 326/million). So Sweden is being hit harder than the overall US on a deaths per population basis but has had less of a problem than much of Western Europe, for whatever that's worth.
But many Brazilians are angry and fearful and self-quarantining despite no official orders. Same with Ecuador. I don't know about Sweden. And one thing I think is important to take into account is that there have to be some original carriers, so most of Latin America and Africa haven't seen many cases because there just isn't much travel. Most people aren't traveling internationally (especially not to China) and coming back infected. Which is one reason the richer countries have been hit harder, if there was a lot of traffic between China and country X in December, January, February, they were going to get screwed, pretty hard to fault their healthcare system or government or anything else. Plus, of course, the availability of testing, the ability to test, an informed population, etc. differ greatly between developed and developing countries.
Plus these countries often have more worrisome problems on their hands. Like starving to death (about 1/3 of Mexico lives day to day, I'm assuming the overall Latin American statistics are similar if not worse), being robbed or kidnapped, diabetes, plenty of other infections like zika or dysentery, etc. Poverty is quite the killer. And I'd much rather have coronavirus (don't have it as far as I know) than be kidnapped and held for ransom (has happened to me, not fun).
