Facial cleanliness and environmental improvement are key to eliminating trachoma

Trachoma is a leading cause of preventable blindness. It is caused by a bacterial infection transmitted through contact with eye-seeking flies, fingers and fomites. Facial cleanliness and environmental improvement are primary prevention components of WHO’s SAFE strategy for trachoma elimination. Water is required for face washing to remove eye discharges. Environmental improvement includes safe disposal of excreta to reduce fly populations.
