In 1993, local, state, and territorial health departments reported to CDC 58,538 cases of acquired immunodeficiency syndrome (AIDS) among racial/ethnic minorities (Table 1). A total of 38,544 (66%) cases were reported among blacks, 18,888 (32%) among Hispanics, 767 (1%) among Asians/Pacific Islanders, and 339 (1%) among American Indians/Alaskan Natives. These cases represented 55% of the 106,949 AIDS cases reported in the United States in 1993. Rates of AIDS and modes of human immunodeficiency virus (HIV) exposure varied substantially both among and within minority populations. This report describes these differences and summarizes the epidemiologic characteristics of AIDS cases reported among racial/ethnic minorities during 1993.
