Onchocerciasis, also known as river blindness and Robles disease, is a disease caused by infection with the parasitic worm Onchocerca volvulus. Symptoms include severe itching, bumps under the skin, and blindness. It is the second most common cause of blindness due to infection, after trachoma. The parasite worm is spread by the bites of a black fly of the Simulium type.
River blindness effects both the eyes and skin, and is caused by infection of the parasitic worm known as the Onchocerca Volculus. This worm is transmitted by fly bites, typically from the notorious blackfly that breeds in rivers, which is where the diseaseâs name originates from.
