Onchocerciasis

Onchocerciasis, also known as “river blindness”, is a parasitic skin and eye disease. It is caused by the filarial worm Onchocerca volvulus, which is spread by the black fly. The disease affects millions of people worldwide, mainly in Africa, Latin America, and Yemen. Symptoms of onchocerciasis include intense itching, rash, eye inflammation, and in severe cases, permanent blindness. Treatment for onchocerciasis is available, however, due to a lack of resources it is often inaccessible and not utilized. If left untreated, the condition can cause severe damage to the eyes and lead to permanent vision loss. The disease is usually preventable and can be controlled using vector control, such as insecticides and eliminating breeding sites. Early detection and treatment is key in preventing the spread of the disease.
