Trichomonas vaginalis (TV) is a little known sexually transmitted infection (STI) that presents complications for infected individuals. In the absence of data in Reunion Island, our aim was to estimate the prevalence of TV and to study the risk factors and clinical signs associated with this infection.
Between January 2020 and December 2022, all persons tested for TV at the University Hospital (UH) and STI centres (CeGIDDs) of Reunion Island were included in this study. TV prevalence was estimated based on the results of the multiplex PCR tests on samples collected from genital, anal or oropharyngeal sites.
Out of the 17,261 samples (from 13,847 patients) included, 310 were positive for TV (30 from CeGIDDs and 280 from UH), representing overall TV prevalence of 2.20 % (95 % CI: 1.99-2.49). The prevalence of TV was 0.80 % (95 % CI: 0.52-1.10) in CeGIDDs (n = 3,733) and 2.80 % (95 % CI: 2.45-3.09) in UH (n = 10,114). In the CeGIDD population, prevalence of TV was 1.15 % (95 % CI: 0.71-1.8) for women, compared with 0.47 % (95 % CI: 0.22-0.90) for men. TV was statistically significantly associated with precariousness (aOR 3.13, 95 % CI: 1.46-6.46), and 23.3 % (7/30, 95 % CI: 8.20-38.47) of TV-positive patients had symptoms.
Compared to other countries, Reunion Island is one of the lower-risk areas for TV. Its presence is associated with poor living conditions and a paucity of clinical signs.
阴道毛滴虫（TV）是一种鲜为人知的性传播感染（STI），会给感染者带来并发症。由于留尼汪岛缺乏相关数据，我们的目的是估计TV的患病率，并研究与这种感染相关的危险因素和临床症状。
在2020年1月至2022年12月期间，留尼汪岛大学医院（UH）和性传播感染中心（CeGIDDs）所有接受TV检测的人都被纳入本研究。TV患病率是根据从生殖器、肛门或口咽部位采集的样本进行多重PCR检测的结果来估计的。
在纳入的17261份样本（来自13847名患者）中，310份TV呈阳性（30份来自CeGIDDs，280份来自UH），总体TV患病率为2.20%（95%CI：1.99 - 2.49）。CeGIDDs（n = 3733）的TV患病率为0.80%（95%CI：0.52 - 1.10），UH（n = 10114）的TV患病率为2.80%（95%CI：2.45 - 3.09）。在CeGIDD人群中，女性的TV患病率为1.15%（95%CI：0.71 - 1.8），而男性为0.47%（95%CI：0.22 - 0.90）。TV与不稳定状况在统计学上显著相关（调整后的比值比为3.13，95%CI：1.46 - 6.46），23.3%（7/30，95%CI：8.20 - 38.47）的TV阳性患者有症状。
与其他国家相比，留尼汪岛是TV感染风险较低的地区之一。其存在与生活条件差和临床症状少有关。
