AIDS is a life-threatening disease and those infected are often treated as invaders although they are the ones who were invaded. Although AIDS first appeared in the United States in the early 1980's, HIV "first gained a foothold in humans some fifty or more years ago in Africa. (Joseph, M.D., 14) At that time many hunters and their families killed and ate monkeys that carried the then undiagnosed and unnamed virus. Stephen C. Joseph, M.
