Visceral leishmaniasis (VL) is a vector-borne protozoan neglected tropical disease. In some parts of Ethiopia, it is a public health problem and its main causative agent is . The objective of the study was to determine the seroprevalence of VL and factors associated among the asymptomatic pastoral community of Dire District, Borena Zone, Oromia Region, Ethiopia. A community-based study was conducted among 432 pastoralist communities from June to July 2021. A systematic random sampling method was used to select households. Pretested structured questionnaires and face-to-face interviews were used to collect data. A single finger-prick blood sample was collected and tested for using an immune-chromatographic test (rk39-ICT). A logistic regression model was used to assess factors associated with VL infection and a -value of < 0.05 was considered statistically significant. A total of 432 study participants were included (their mean age was 26.69) and 218 (50.5%) were females. The overall seroprevalence of VL was 33/432(7.6%) (95%CI: 5.32-15.60). Sero-prevalence was significantly associated with high family size (>5) (adjusted odds ratios (AOR) = 5.134; 95% CI: 2.032-9.748), sleeping or/and staying under acacia tree (AOR = 2.984; 95%CI = 1.074-8.288), presence of cracked house walls (AOR = 1.801; 95%CI: 1.026-4.926), presence of termite hills (AOR = 1.938; 95%CL: 1.002-7.050), availability of water points (AOR = 3.893; 95%CI: 1.034-7.426) and presence of domestic animals (AOR = 2.124; 95% CI: 2.341-5.108). It is recommended that community awareness on the transmission and prevention methods of and taking appropriate interventions on the identified factors play a greater role to prevent and control infection in the area. Further investigation is also needed to characterize the pathogens and risk factors and tackle the problem.
内脏利什曼病(VL)是一种由媒介传播的原生动物性热带病。在埃塞俄比亚的一些地区,它是一个公共卫生问题,其主要病原体是 。本研究的目的是确定无症状牧民社区的 VL 血清流行率及其相关因素。这是一项 2021 年 6 月至 7 月在博雷纳地区迪雷区进行的基于社区的研究。采用系统随机抽样方法选择家庭。使用经过预测试的结构化问卷和面对面访谈收集数据。采集单指血样,并用免疫层析试验(rk39-ICT)检测 。采用逻辑回归模型评估与 VL 感染相关的因素,p 值<0.05 认为具有统计学意义。共纳入 432 名研究参与者(平均年龄为 26.69 岁),其中 218 名(50.5%)为女性。VL 的总血清流行率为 33/432(7.6%)(95%CI:5.32-15.60)。血清流行率与大家庭规模(>5 人)(调整后的优势比(AOR)=5.134;95%CI:2.032-9.748)、在金合欢树下睡觉或/和停留(AOR=2.984;95%CI=1.074-8.288)、房屋墙壁有裂缝(AOR=1.801;95%CI:1.026-4.926)、有白蚁丘(AOR=1.938;95%CL:1.002-7.050)、有水源点(AOR=3.893;95%CI:1.034-7.426)和有牲畜(AOR=2.124;95%CI:2.341-5.108)有关。建议在该地区开展针对 和预防方法的社区宣传,采取针对已确定因素的适当干预措施,以预防和控制感染。还需要进一步调查以确定病原体和风险因素,并解决这一问题。
