Medellin has a bunch of crackheads and IV drug users literally a crack rock throw away from the casas. AIDS is likely to come from drug users and locals who use the casas near the skid row parque Fernando area, before eventually going to the hotspots. Got to remember the locals trick too, and the hoes from centro move to lleres at night.
Could it be mongers? Sure but Brazil is next door and always had an aids/hiv issue. Venezuela has $1 hookers, since at least 2018. I mean I’ll look at other factors before trusting YouTube, because as even said the people didn’t even want to get tested, so if it was shit spreading, you wouldn’t be able to get an origin, only assumptions and theories.
