I grew up in a rural area in a second-world country, during the 90ies when the economy went from shitty to complete shit, and many people had to subsist on grazing, so to speak: I helped to plant (and then gather) potatoes, tomatoes and other vegetables in our backyard. But even then, lices were mostly something out of WW2-era stories, or something you'd get if you hanged out with local "wandering folk", I guess; I don't remember any lice cases in my school although we did have our hair checked in the elementary.

Then things generally improved and life is now much better; so what about the lices? According to the 2019 statistics, there were 200 cases of headlice per 100'000 children that year. Quite a number, but not a huge one, really.

So that's why I asked--if in a poor second-world country lices were almost a non-issue, then surely that means the rich first-world countries have managed to completely get rid off the lice, and much earlier, too? Right?
