The human immunodeficiency virus epidemic in Zimbabwe is slowing down because of a large-scale change in sexual behavior, particularly among young and educated people. Gregson et al. (p. 664; see the Perspective by Hayes and Weiss) present an analysis that disentangles decline from the mortality of high-risk subpopulations and a lower infection rate of young people. These trends may be taking place across much of sub-Saharan Africa and seem to result from a combination of national program activities, condom use, and increased fear of death from AIDS.
