Although male homosexual activity has been reported as a risk factor for hepatitis A, the frequency with which homosexual activity was reported by persons with hepatitis A was less than 10% during 1982-1989 (CDC unpublished data, 1990). However, in June of 1991, CDC received reports from several cities in the United States, Canada, and Australia of an increase in hepatitis A among homosexual men during the first 6 months of 1991. This report summarizes data from each of these cities.
尽管男性同性恋活动已被报告为甲型肝炎的一个危险因素，但在1982 - 1989年期间，甲型肝炎患者报告的同性恋活动频率低于10%（疾病控制与预防中心未发表的数据，1990年）。然而，1991年6月，疾病控制与预防中心收到来自美国、加拿大和澳大利亚几个城市的报告，称1991年上半年男同性恋者中甲型肝炎病例有所增加。本报告总结了这些城市各自的数据。
