i dont think it's as simple as they make out with that title.
the use of condoms promotes sex, which is against the religion outside of marriage. it also makes people want to have sex more, which spreads the disease more. when people come out of the cycle of having sex, they will crave it for a few weeks, but after that they dont feel the urge, so would probably lower the spread. also condoms arnt as safe as the ones that we get, they arnt put through the same tests and quality controls. since most people are so poor there anyway, i dont see how they would spare anything to buy them.
