10 Facts About Guinea Worm Disease

Dracunculiasis, or Guinea worm disease is, by all accounts, pretty awful: A person with the disease hosts a parasitic worm that forms a painful blister under the skin that eventually bursts, allowing the worm to emerge and lay its eggs in water. Those afflicted don't just endure pain (although there's plenty of that); they also run the risk of secondary infection and permanent paralysis, and there are economic consequences to the disease, too.
