to keep this short. I lived in Africa. There ARE western type "civilized" *cringe* cities. I never noticed screens in windows or doors and the homes are very open. Hence the malaria epidemic which they are very concerned about. One thing was there was only one doctor for two countries.. COUNTRIES. When I lived in the village... hours away from any sort of clinic the entire area all drank out of the same pond. A pond of about 800 square feet (small puddle you could walk around in 2 minutes). This was also the ONLY water supply for any goat, mule, chicken whatever animal might be there for miles. So you drank along side a goat in sitting water and no mosquito nets or doors or anything to hide from the bugs. Also everyone in the community drank from the same pitcher (beer is the only other thing they drank as it was the safest thing they can make).

So yeah.. I can see how disease would spread when no one washes their hands let alone their bodies and uses the road as a restroom (very common to just take a few steps over and pee where you were.. skirts are great for that) and who knows if that goes into the well water or not (not a big concern I would think).
Â
And then you have shanti towns sitting just outside of towns with one water spout for 500,000 people.

I seriously doubt measles is even on their minds. AIDS and malaria and clean water are. Rape and murder is also really common.
