Dracunculiasis

After leaving office, former U.S. President Jimmy Carter led a decades-long effort to eradicate Guinea worm disease, and he nearly lived to see it happen.

Researchers reported the first known case of human Dracunculus worm infection in Vietnam. The case was caused by an unknown species of worm that was determined not to be the species that causes dracunculiasis, or Guinea worm disease.
