The native American Indians knew not to drink from stagnant water thousands of years ago. Back in Moses’ time, the reason for food being halal was due to health reasons. So, how many generations of third worlders have to be taught and re-taught simple skills they should have known and they still don’t get it. It’s not just cholera. How difficult is it to grasp this is a dried corn kernal, poke it into the ground, water it, when it sprouts pick the grasshoppers off it and in three months you have food? Heck, roast up those grasshoppers to stay alive. Surely, a handful of villagers can get together and hand dig a well for the tribe in a couple day’s time. But no, they wait for a do-gooder to build one for them while they let flies eat their babies. Helloooo, swat the dadgum flies and poop in a designated poo place and maybe, just maybe, your babies won’t die.
Our modern health is exactly that. Modern.
Word hasn't gotten out to all of the world yet.
Try not to be too smug. We aren't that far removed from them in time or space.
