In view of gathering baseline information about the prevalence of animal trypanosomosis, the Pan African Tsetse and Trypanosomiasis Eradication Campaign (PATTEC) funded a cross sectional survey in the region of the Boucle du Mouhoun which constitutes the Northern limit of the tsetse distribution in Burkina. This cross sectional study was carried out in 53 villages located in the six provinces of the region. A total of 2002 cattle, 1466 small ruminants and 481 donkeys were sampled. This survey showed that about 25% of the cattle had been treated with trypanocidal drugs within 3 months before the survey compared to 3% and 0.42% for the small ruminants and donkeys, respectively. Parasitological prevalence in cattle was low: 0.77% (95% C.I. 0.30-1.95%). No goats and three donkeys were found infected with trypanosomes. Infections were mainly due to Trypanosoma vivax (75.0%) with cases of Trypanosoma congolense (25.0%). In cattle, the serological prevalence of trypanosomosis, for the entire region of the Boucle du Mouhoun, was 34.2% (95% C.I. 26.1-43.4%). For sheep, goats and donkeys, the prevalence were of 20.9% (95% C.I. 12.2-33.5%), 8.5% (95% C.I. 5.7-12.5%) and 5.8% (95% C.I. 3.9-8.6%), respectively. The age and distance to the river were the two main risk factors associated with seropositivity.
鉴于收集动物锥虫病流行率的基线信息，泛非采采蝇和锥虫病根除运动（PATTEC）资助了在布基纳法索的采采蝇分布的北部边界布克莱迪穆洪地区进行的横断面调查。这项横断面研究在该地区的 6 个省的 53 个村庄进行。共采集了 2002 头牛、1466 只小反刍动物和 481 匹马。这项调查显示，与小反刍动物（3%）和马（0.42%）相比，大约 25%的牛在调查前 3 个月内接受了抗锥虫药物治疗。牛的寄生虫病流行率较低：0.77%（95%置信区间为 0.30-1.95%）。没有发现感染锥虫的山羊和 3 匹马。感染主要是由锥虫（75.0%）引起的，其中有 25.0%的病例是由刚果锥虫引起的。在牛中，整个布克莱迪穆洪地区的锥虫病血清流行率为 34.2%（95%置信区间为 26.1-43.4%）。绵羊、山羊和马的流行率分别为 20.9%（95%置信区间为 12.2-33.5%）、8.5%（95%置信区间为 5.7-12.5%）和 5.8%（95%置信区间为 3.9-8.6%）。年龄和与河流的距离是与血清阳性相关的两个主要危险因素。
