We expect Guinea Worm to be the second disease in the history of the world to be completely eradicated from the face of the Earth.

Former President Jimmy Carter in a conversation with Scientific American Editor-in-Chief Mariette D. Christina at the American Museum of Natural History in New York City on January 12th.

Can you speak to the Carter Center's work in Guinea Worm? And the progress since you began working on
