When The Carter Center began leading the international campaign to eradicate Guinea worm disease in 1986, there were an estimated 3.5 million cases in 21 countries in Africa and Asia. Today, that number has been reduced by more than 99.99 percent.

In 2017, 30 human cases of Guinea worm disease were reported worldwide.
