Acquired immune deficiency syndrome.

Acquired Immune Deficiency Syndrome (AIDS) occurs as a result of a defect in cell mediated immunity with a comparatively normal humoral immunity. Originally diagnosed in four distinct groups, AIDS is now recognized in six high-risk groups. Many theories of etiology exist; the most accepted etiologic agent is the Human T-lymphotropic retrovirus (HTLV). Clinical presentations are that of an opportunistic infection or a nonspecific illness. Once AIDS is diagnosed, medicine has little to offer the AIDS victim. CDC recommendations for health personnel and AIDS patients are reviewed.
