    AIDS is a fatal disease that breaks down the body's ability to defend itself against illness and infectio

    AIDS is especially dangerous because a long time(typically five years) elapses between someone's first exposure to the AIDS viru

    and actual development of the diseas

    and they probably don't even know they have i
