I need info on Aids in Africa

I have a very good friend who wants me to go to Gambia with him and his wife. To be honest its simply a sex holiday. My mates wife whom is actually a Gambian muslim ( with whom I get on very well) is constantly onto me about it. She has this lovely little 22 year old lined up for me but I'm worried about getting Aids.
I've thought this through and obviously the girl in question only wants a British passport but that's fine by me. My mate is on his 2nd African wife after the 1st ran off after she gained all the neccesary paperwork to stay for good, he is 72 afterall and his present wife is only 29 with a lovely arse n tits. However, her hygiene leaves something to be desired.
I don't really need help with the ladies but I'm thinking after the novelty wears off she can cook and clean for me whilst I revert back to the single life and even rent her out to earn me a few bob, I've seen a pic and she's quite fit trust me.
Now I've tried googling Aids in Africa but it just comes up with info I don't need so can anyone help me with the percentages and locations of the blackspots please.
