The study was conducted to define the contact-tracing success rate of the partner notification services routinely provided by the community-based youth health centres and the county medical officer for communicable disease control (CMO) in Uppsala County, Sweden.
The study had three goals, (i) to register the number of sexual partners routinely reported by each diagnosed index case with CT and the success rate in tracing and testing these partners for CT infection. (ii) To analyse the current notification practices in reporting the number of cases of unsuccessful contact tracing to the CMO. (iii) To determine the contact tracing success rate of the partner notification services provided by the CMO.
Each diagnosed case of CT is obliged by law to participate in the contact-tracing procedure performed by the physician managing the patient or by a specialised sexually transmitted infection (STI) adviser. Successful contact-tracing is defined as the confirmed attendance of a sexual contact within 12 months of the contact with the index case.
The number of CT cases diagnosed by the youth health centres during the study period was 463 (299 females and 164 males). The females reported 660 male sexual contacts and the males reported 386 female contacts. Successful partner notification was achieved for 73% of all sexual contacts. 284 (190 females and 94 males) unsuccessful partner notifications were reported to the CMO of whom 98 (52%) of the female contacts and 20 (21%) of the male contacts were successfully notified by the CMO. However, for 134 (71 females and 63 males) partners, personal details given by the index case were insufficient for identification of the partner.
When asymptomatic, genital CT infection spreads among sexually active young adults with multiple, unidentified sexual partners, appropriate methods of partner notification are not sufficient to achieve its aims at the population level.
本研究旨在确定瑞典乌普萨拉郡社区青年健康中心和负责传染病控制的县医务官（CMO）常规提供的性伴侣追踪服务的成功率。
本研究有三个目标，（i）记录每位确诊的索引病例常规报告的沙眼衣原体（CT）性伴侣数量，以及追踪和检测这些伴侣是否感染CT的成功率。（ii）分析当前向CMO报告接触者追踪未成功病例数量的通报做法。（iii）确定CMO提供的性伴侣追踪服务的成功率。
法律规定，每例确诊的CT病例都必须参与由负责治疗该患者的医生或专业性传播感染（STI）顾问进行的接触者追踪程序。成功的接触者追踪定义为性接触者在与索引病例接触后12个月内确认就诊。
在研究期间，青年健康中心诊断出463例CT病例（299例女性和164例男性）。女性报告了660名男性性伴侣，男性报告了386名女性性伴侣。所有性接触中73%实现了成功的性伴侣通报。向CMO报告了284例（190例女性和94例男性）性伴侣通报未成功的情况，其中CMO成功通报了98例（52%）女性接触者和20例（21%）男性接触者。然而，对于134例（71例女性和63例男性）伴侣，索引病例提供的个人详细信息不足以识别该伴侣。
无症状的生殖器CT感染在有多个身份不明的性伴侣的性活跃青年中传播时，适当的性伴侣通报方法在人群层面上不足以实现其目标。
