A crude example, if the life expectancy of an aids afflicted african is half that of one that is not afflicted, and the prevalance rate is 20%, then 33% of the population will get HIV/AIDS.You could be right!
It's because they die the prevalance rate goes down, while the affliction rate is unaltered.
Some organisations have tried to take credit for successfully combatting HIV/AIDS on basis of the prevalence rate going down (won't mention any), but the truth lies elsewhere. I don't know if it is because of ignorance or propagande they do this.
15-17% prevalance rate would suggest 25-30% risk of affliction in 2006-2007 - crudely put, as I don't know the numbers.
