Education, education, education.
I've read where, in Africa... because of the poverty... they salvage plastic syringes from the garbage and reuse them. Plastic syringes can't be sterilized. Supposedly this is one of the biggest factors in the AIDS epidemic.
Geez... I don't know. I think that the 'Western' countries have more of a handle on it...but how would you get mass populations to follow those medical dictates without governmental intervention and/or help?
No the western approach has been condemned by the catholic church as evil "condoms will make you impotent" most nations hate western prevention methods. So we need to present something as new and non-western.And educate first.
