The Project for Water Supply and Guinea Worm Eradication, Burkina Faso
The disease is caused by Guinea worm (a round worm family), which enters into human body when people drink filthy pond water infested with Cyclops as the intermediary host harboring larvae of Guinea worm. A year later adult females carrying larvae come out of the extremities of human body breaking through the skin, which causes great pain. The incidence of the disease reached 3,231 in 1996 in Burkina Faso and had become one of the most urgent matters to be solved. The only remedy to the problem is to avoid infested water. In order to supply 20 liters of clean water per person per day to the people in 225 villages in 9 most affected provinces, 258 boreholes with hand pumps were constructed.
