Chlamydia trachomatis infection (CTI) is the most frequent sexually transmitted infection in western countries. Its prevalence in undocumented immigrants, a rapidly growing vulnerable population, remains unknown. We aimed to document the prevalence of CTI and associated factors at the primary health care level. This cross-sectional study included all undocumented immigrants attending a health care facility in Geneva, Switzerland. Participants completed a questionnaire and were tested for CTI by PCR assay. Three-hundred thirteen undocumented immigrants (68.4% female, mean age 32.4 (SD 8) years) agreed to participate. CTI prevalence was 5.8% (95% CI 3.3-8.4). Factors associated with higher prevalence were age ≤25 (OR 3.9, 95% CI 1.3-12.2) and having had two or more sexual partners during the precedent year (OR 4.5, 95% CI 1.5-13.7). Prevalence and associated factors for infection in this vulnerable population were comparable with other populations in Western countries. Our findings support the importance of facilitating access to existing screening opportunities in particular to individuals at higher risk.
沙眼衣原体感染（CTI）是西方国家最常见的性传播感染。在无证移民这一快速增长的弱势群体中，其流行情况尚不清楚。我们旨在记录初级保健水平的 CTI 患病率及其相关因素。本横断面研究纳入了所有在瑞士日内瓦一家医疗保健机构就诊的无证移民。参与者完成了一份调查问卷，并通过 PCR 检测进行 CTI 检测。共有 313 名无证移民（68.4%为女性，平均年龄 32.4（8）岁）同意参与。CTI 的患病率为 5.8%（95%CI 3.3-8.4）。与更高患病率相关的因素是年龄≤25 岁（OR 3.9，95%CI 1.3-12.2）和在过去一年中有两个或更多性伴侣（OR 4.5，95%CI 1.5-13.7）。在这个弱势群体中，感染的患病率和相关因素与其他西方国家的人群相当。我们的研究结果支持为特别高风险人群提供现有筛查机会的重要性。
