  1. “River blindness is caused by a parasitic worm that lives under the skin – blindness is just one of the symptoms of this devastating human parasite.
    River blindness is primarily an African disease, common in central Africa, especially in villages near rivers and streams. A parasitic disease, it is caused by a large tissue roundworm that spreads from person to person through the bites of blackflies. The association with rivers occurs because this is where blackflies breed—in rivers where the water flows quickly, the humidity is high, and there is lots of plant growth.”
