River blindness, or onchocerciasis, is a parasitic infection that can cause severe skin irritation, itching and, over time, irreversible blindness. It’s spread by the bite of infected black flies that breed near fast-flowing rivers and is major health problem in Burkina Faso.

To combat River Blindness, Sightsavers is carrying out mass drug administration programmes in the Cascades region, in the country’s south west, distributing medication to treat and prevent the disease.
