Human immunodeficiency virus infection: the spectrum beyond AIDS.

Since 1981, the Acquired Immune Deficiency Syndrome (AIDS) has emerged as the major infectious epidemic of our time. It is the most profound manifestation of infection with the Human Immunodeficiency Virus (HIV). Since 1984, serologic methods have existed to detect antibody to HIV. Several other clinical entities have been detected and are attributable to HIV infection. Appropriate counsel must accompany antibody testing. The author discusses the acute seroconversion event, as well as asymptomatic carrier status, including generalized lymphadenopathy. He also reviews the symptomatic states that do not meet the surveillance definition of AIDS, including treatments where available.
