To estimate the number of persons infected with the human immunodeficiency virus (HIV) living in the United States and the change in HIV infection prevalence since 1984. ⋯ The 3 different data sources and methods are consistent in estimating that 650,000 to 900,000 persons were infected with HIV in the United States in 1992. Among adolescents and adults of both sexes, the proportion infected was substantially higher among non-Hispanic blacks and Hispanics than among non-Hispanic whites. HIV-related illness will be a major clinical and public health problem in the United States for years to come.

To estimate the economic impact of (1) treating pregnant women who are human immunodeficiency virus (HIV)-positive with zidovudine and (2) voluntary screening programs for pregnant women for HIV infection and offering treatment with zidovudine to those found to be HIV-positive. ⋯ Offering zidovudine treatment to pregnant women known to be HIV-positive will decrease the number of cases of pediatric HIV infection and reduce health care costs. Voluntary screening programs for pregnant women will further decrease the number of cases of pediatric HIV infection. The effect of a screening program on health care costs varies according to HIV prevalence and the costs associated with the screening program.
