To estimate the seroprevalence and investigate risk behaviors for HIV (human immunodeficiency virus) infection in intravenous drug users in Los Angeles County, a stratified, random sample of 790 clients, enrolled in either methadone maintenance or detoxification programs, were studied. Thirteen study participants (1.8 per cent) were seropositive; of these, five were homosexual/bisexual males and three were female prostitutes. Ninety-five per cent of all participants reported sharing needles. Risk reduction education efforts must be expanded before the HIV antibody prevalence rate increases.
为了估计洛杉矶县静脉吸毒者中HIV（人类免疫缺陷病毒）感染的血清阳性率并调查其危险行为，我们对790名参加美沙酮维持治疗或戒毒项目的客户进行了分层随机抽样研究。13名研究参与者（1.8%）血清呈阳性；其中，5名是男同性恋/双性恋男性，3名是女性性工作者。所有参与者中有95%报告有共用针头的行为。在HIV抗体流行率上升之前，必须加大降低风险的教育力度。
