Participatory investigation and trypanosomosis prevalence studied during April 2019 and March 2020 in two selected districts of South Omo, Ethiopia. The study site is located in the gridline of 04.90 to 5.60N and 35.80 to 36.90 E. Twelve community groups are employed. A cross-sectional study design and 288 animals bled and examined a wet film prepared from the buffy coat. Sixty NGU traps baited with acetone and cow urine were deployed for 48 hrs to estimate the apparent density. Data generated from focus group discussion and trypanosomosis prevalence analyzed using an appropriate statistical package. Proportional piling showed that cattle, goats, and sheep were proportionally dominant with a high median score of 32(14-40), 26(12-33), and 21(5-23), respectively; trypanosomosis ranked first with a proportional median score of 24(13-26) followed by contagious bovine/caprine pleuropneumonia with a proportional median score of 23(19-26) among others. Community unanimously agreed that ( = 0.9) trypanosomosis affects their socioeconomic status and was able to describe clinical signs with significant ( < 0.05) agreement. Tsetse fly (Echut and Kusubo) is the main vector with the agreement of = 0.9( < 0.05). Perception on human trypanosomosis varies between Benna Tsemay and Gnagatom districts. Therefore, further study supported by laboratory like molecular test is very important to conclude the presence of human trypanosomosis in the suggested area. The overall prevalence of cattle trypanosomosis was 10.1%. The prevalence of trypanosomosis was significantly higher in poor body condition (OR = 2.1, < 0.05) and in black coat color (OR = 13.5, < 0.05) animals. and were circulating in the area. A total of 455 (385 , 17 , and 53 ) were trapped. The overall apparent density of was 3.79 Flies/Trap/Day. Three species of Glossina, namely , and , were distributed in the study areas. Therefore, the finding suggests that the problem is significant and the human trypanosomosis is doubtful. Hence regular control measures and molecular diagnosis need to be conducted.
2019年4月至2020年3月期间，在埃塞俄比亚南奥莫的两个选定地区进行了参与式调查和锥虫病流行情况研究。研究地点位于北纬04.90至5.60度、东经35.80至36.90度的网格线内。雇佣了12个社区小组。采用横断面研究设计，采集了288只动物的血液，并对从血沉棕黄层制备的湿涂片进行了检查。部署了60个用丙酮和牛尿诱饵的NGU诱捕器，放置48小时以估计表观密度。通过焦点小组讨论生成的数据和锥虫病流行情况使用适当的统计软件包进行分析。比例排序显示，牛、山羊和绵羊在比例上占主导地位，中位数得分分别为32（14 - 40）、26（12 - 33）和21（5 - 23）；锥虫病以24（13 - 26）的比例中位数得分排名第一，其次是传染性牛/山羊胸膜肺炎，比例中位数得分为23（19 - 26）等。社区一致认为（= 0.9）锥虫病影响他们的社会经济地位，并且能够以显著（< 0.05）的一致性描述临床症状。采采蝇（Echut和Kusubo）是主要传播媒介，一致性为 = 0.9（< 0.05）。本纳·采迈和格纳加托姆地区对人类锥虫病的认知有所不同。因此，由分子检测之类的实验室支持的进一步研究对于确定建议地区是否存在人类锥虫病非常重要。牛锥虫病的总体流行率为10.1%。身体状况差的动物（OR = 2.1，< 0.05）和黑色被毛颜色的动物（OR = 13.5，< 0.05）中锥虫病的流行率显著更高。 和 在该地区传播。总共捕获了455只（385只 ，17只 ，53只 ）。 的总体表观密度为3.79只/诱捕器/天。舌蝇属的三个物种，即 、 和 ，分布在研究区域。因此，研究结果表明该问题很严重，而人类锥虫病情况存疑。因此需要采取定期控制措施并进行分子诊断。
