In the past three years cases of shigellosis, amoebiasis, and viral hepatitis A and B have increased fourfold to tenfold in San Francisco. These diseases were most common in people who had adopted "alternative life-styles", especially in young men, In many cases there was a history of frequent orogenital and oral-anal sexual contact between men with no common source. Despite energetic public-health measures and intensive efforts by physicians treating these cases, the increase has not yet been brought under control. Other cities may experience similar difficulties with sexual transmission of enteric diseases.20
在过去三年里，旧金山的志贺氏菌病、阿米巴病以及甲型和乙型病毒性肝炎病例增加了四倍至十倍。这些疾病在采取“另类生活方式”的人群中最为常见，尤其是年轻男性。在许多病例中，男性之间存在频繁的口交和口肛性接触史，且无共同传染源。尽管采取了积极的公共卫生措施，治疗这些病例的医生也付出了巨大努力，但病例的增加仍未得到控制。其他城市在肠道疾病的性传播方面可能也会遇到类似困难。
