In onchocerciasis-endemic communities, black fly vectors of cause annoyance. No vector control was performed in Cameroon to complement ivermectin treatment despite high fly densities in the savannah and forest areas. This study assessed the knowledge and practices of four onchocerciasis-endemic communities in Sudan and the Guinea savannah in Cameroon. We surveyed four communities using a structured questionnaire. We interviewed 452 individuals (Mawong: 136, Befang: 160, Soramboum: 88, and Galim: 68) aged 14-50 years. Most respondents (90%) knew about black flies being a nuisance but had misconceptions about their bite's effect, location, and season. Only 9.3% knew that black fly bites could lead to blindness, whereas 34.1% correctly regarded evenings as the biting period. In Savannah, Sudan, 30.9% of the interviewees stated that black flies bite both outdoors and indoors, and 37.0% of the enrolees believed that black flies bite any exposed body part. In the Guinea savannah, 61.1% of respondents agreed that black flies typically bite during the dry season. Proper clothing can protect against black fly bites, but the transmission mode and vector biology are poorly understood. Implementing community-based vector surveillance can help fight onchocerciasis and reduce black fly nuisance.
在盘尾丝虫病流行社区，传播该病的黑蝇会造成困扰。尽管喀麦隆的稀树草原和森林地区黑蝇密度很高，但该国未采取病媒控制措施来辅助伊维菌素治疗。本研究评估了苏丹以及喀麦隆几内亚稀树草原地区四个盘尾丝虫病流行社区的相关知识和做法。我们使用结构化问卷对四个社区进行了调查。我们采访了452名年龄在14至50岁之间的个体（马翁：136人、贝方：160人、索兰布姆：88人、加利姆：68人）。大多数受访者（90%）知道黑蝇会造成困扰，但对其叮咬的影响、部位和季节存在误解。只有9.3%的人知道黑蝇叮咬会导致失明，而34.1%的人正确地认为傍晚是叮咬时段。在苏丹的稀树草原地区，30.9%的受访者表示黑蝇在户外和室内都会叮咬，37.0%的受访者认为黑蝇会叮咬任何暴露的身体部位。在几内亚稀树草原地区，61.1%的受访者认为黑蝇通常在旱季叮咬。合适的衣物可以防止黑蝇叮咬，但人们对传播方式和病媒生物学了解甚少。实施基于社区的病媒监测有助于防治盘尾丝虫病并减少黑蝇造成的困扰。
