This is true, just a small correction for clarity. AIDS isn't really a set of symptoms. Its defined as an HIV infection that has progressed to a point where the person has a CD4 count under 200 or has an "AIDS-defining condition". The 2 often go hand in hand because these AIDS defining conditions usually happen at very low CD4 counts. So you can have AIDS and then actually regress back to just an HIV infection with HAART when the CD4 count recovers.
