During 1989, state and territorial health departments reported 35,238 cases (14.0 per 100,000 population) of acquired immunodeficiency syndrome (AIDS) to CDC. Rates (reported cases per 100,000 population) were highest for blacks and Hispanics; for persons 30-39 years of age; in the Northeast region and in U.S. territories (primarily reflecting rates in Puerto Rico); in the largest metropolitan areas; and for men. Rates varied widely among states.* As in previous years, most reported cases occurred among men who had had sex with other men (homosexual/bisexual men) (56%) and among heterosexual intravenous-drug users (IVDUs) (23%).
