Update: trends in AIDS incidence -- United States, 1996.

Provisional surveillance data about acquired immunodeficiency syndrome (AIDS) for the first 6 months of 1996 indicated a decrease in deaths among persons with AIDS, attributed primarily to the effect of antiretroviral therapies on the survival of persons infected with human immunodeficiency virus (HIV). This report describes a decline in AIDS incidence during 1996 compared with 1995 and the continued decline in AIDS deaths; the findings indicate that HIV therapies are having a widespread beneficial impact on the rate of HIV disease progression in the United States.
