That said, these "third-world problems" - by which I think you mean things like parasites, curable / preventable / vaccinatable diseases, "tropical" diseases, and mosquito-borne diseases - are becoming more and more prevalent in the US and Europe because of climate change and other factors - I'm thinking poor health care, aging infrastructure (think Flint), shortcuts (think the UK dumping sewage into the sea because their infrastructure can't handle processing), but also evolution, things like parasites being able to survive better.
