River blindness, or onchocerciasis, is a neglected tropical disease caused by the parasitic worm Onchocerca volvulus, transmitted through the bites of infected blackflies. It leads to severe itching, skin discoloration, and can cause irreversible blindness, primarily affecting communities near fast-flowing rivers in sub-Saharan Africa and parts of Latin America and Yemen.
