These are enveloped RNA cytopathic lentiviruses belonging to the family Retroviridae. Infection is most commonly secondary to HIV-1. HIV-2 is rare in the United States but more common in West Africa. Unless otherwise specified, this chapter addresses HIV-1 infection. HIV results in a broad spectrum of disease, with acquired immunodeficiency syndrome (AIDS) representing the most severe end of the clinical spectrum.
