Tanzania's fight against onchocerciasis.

摘要

Leo Khalfam Msakile is blind, and he does not know why. The middle-aged Tanzanian maize farmer sits on the ground in front of his hut with his five children around him, as his wife tends a pot over a wooden fire. He gestures to his clouded up eyes, which he says began to itch 3 years ago, before his sight failed completely. In his village, Mngazi, 50 people have epilepsy, including his son, and another 20 are becoming blind. Msakile's community has endemic onchocerciasis.
