..........At the time that the controversy started, there were still some questions unanswered on the precise mechanisms of HIV disease. Ten years later there is a more complete understanding of how HIV causes AIDS.
..........AIDS symptoms develop on average approximately 8 to 10 years after initial HIV infection. About 5-10% of HIV-positive individuals develop AIDS symptoms very rapidly during the first years of infection and about the same proportion may be infected with HIV for 15 or more years without progressing to AIDS.
