Considered a neglected tropical disease, Guinea worm disease (dracunculiasis) is contracted when people consume water contaminated with Guinea worm larvae. After a year, a meter-long worm slowly emerges from the body through a painful blister in the skin. In the absence of a vaccine or medical treatment, the ancient disease is being wiped out mainly through community-based interventions to educate and change behavior, such as teaching people to filter all drinking water and preventing contamination by keeping anyone with an emerging worm from entering water sources.Ok, maybe that's not as impressive as Dubya sitting around the house painting pictures of his feet, but it's something.
The Carter Center, together with ministries of health, local communities, and other partners, has reduced cases by more than 99.99 percent since 1986. The Center estimates that the eradication campaign has averted more than 80 million cases among the world's poorest and most neglected people. Guinea worm disease is positioned to be the second human disease, after smallpox, to be eradicated. It will be the first parasitic disease to be eradicated and the first disease to be eradicated without the use of a vaccine or medicine.
