Human immunodeficiency virus (HIV) prevalence was studied in an unselected group of 216 female and transsexual prostitutes. Subjects were asked about age, biological sex, marital status, children, length of occupation, sexual practices, and drug abuse history. Blood was drawn on site. All 128 females who did not admit to drug abuse were seronegative; 2 of the 52 females (3.8%) who admitted to intravenous drug abuse were seropositive. In contrast, 11.1% of the 36 male transsexuals (including 3 out of 32 non-drug abusers) were seropositive. The results support the notion that vaginal transmission of HIV is less effective than anal transmission.
在一组未经挑选的216名女性和变性妓女中研究了人类免疫缺陷病毒（HIV）的流行情况。询问了受试者的年龄、生理性别、婚姻状况、子女情况、职业年限、性行为及药物滥用史。在现场采集血液。所有128名不承认有药物滥用的女性血清学检测均为阴性；52名承认有静脉药物滥用的女性中有2名（3.8%）血清学检测呈阳性。相比之下，36名男性变性者中有11.1%（包括32名非药物滥用者中的3名）血清学检测呈阳性。这些结果支持了HIV经阴道传播不如经肛门传播有效的观点。
