Give it about 10-20 years and the AIDS problem should fix itself.
I have a hard time imagining any reason that I should pay money that I worked for to fix a problem on another continent that the governments there refuse to deal with on their own. People send AIDs drugs, the local governments block the deliveries. People try sending condoms, the locals won't use them. Global agencies warn about the dangers of unprotected sex, like anyone is going to listen to that; People in the civilized world can't even figure that one out. Prevention, Education and treatment have all been tried, the next step is sit back and wait.
We can only do so much and throwing money at this problem won't fix it. Let the populations die off, governments across the globe have tried long enough to no avail. You can't help those who won't help themselves.
Things were better when it was two guys in a dorm room.
