The result revealed a low level of knowledge about the cause, prevention and complications of onchocerciasis. Respondents have developed a cultural system around the disease due to long exposure. The majority are aware of the disease which they recognize once their body starts itching or musculoskeletal pain develops but only 64.4, 34.0, 1.4 and 3.6%, respectively attributed chronic itching, nodules, bad vision and leopard skin to blackfly bite.
