Cause of Guinea worm disease
The parasite Dracunculus medinensis causes the infection. The infection spreads to humans when a person drinks water contaminated by water fleas that harbor Guinea worm larvae. The larvae then grow into adult worms (2-3 feet in length) in the small intestine and then migrate and emerge from the skin. GWD affects poor communities in remote parts of Africa that do not have safe water to drink.
