During 1991, state and territorial health departments reported 45,506 cases (17.9 per 100,000 population) of acquired immunodeficiency syndrome (AIDS) to CDC. As in previous years, most cases (52.7%) were attributable to human immunodeficiency virus (HIV) transmission among homosexual/bisexual men. The proportion of cases among these men during 1991 decreased from that in 1990, while the proportions among women and heterosexual men who were injecting-drug users (IDUs) increased, representing nearly one fourth of reported cases in 1991. This report summarizes the characteristics of persons reported with AIDS in 1991 and compares these data with 1990 (Table 1).*
1991年期间，各州及地区卫生部门向疾病控制与预防中心报告了45506例获得性免疫缺陷综合征（艾滋病）病例（每10万人中有17.9例）。与往年一样，大多数病例（52.7%）归因于同性恋/双性恋男性之间的人类免疫缺陷病毒（HIV）传播。1991年这些男性中的病例比例较1990年有所下降，而女性以及注射吸毒的异性恋男性中的病例比例有所上升，占1991年报告病例的近四分之一。本报告总结了1991年报告的艾滋病患者的特征，并将这些数据与1990年的数据进行了比较（表1）。
