Onchocerciasis. Treatment with ivermectin (Date taken unknown)
Onchocerciasis treatment distribution. Third World health worker giving a woman an ivermectin tablet for the treatment of onchocerciasis ('river blindness'). A queue of villagers are waiting for their tablet. Onchocerciasis is caused by the infective tiny worms (microfilariae) of Onchocerca volvulus. The worms are transmitted from person to person by biting flies which breed in rivers. Blindness occurs as an allergic reaction when these worms die in or near tissues of the eye. Ivermectin is highly effective at killing the worms when given in doses 6-12 months apart. Photographed in Mali.
