Progress Toward Global Eradication of Dracunculiasis — Worldwide, January 2021–June 2022

What is already known about this topic?

Human cases of dracunculiasis (Guinea worm disease) have decreased from an estimated 3.5 million in 1986 to 15 in 2021. Emergence of Guinea worm infections in dogs in 2012 has complicated eradication efforts.

What is added by this report?

Fifteen cases in humans were reported in 2021 and three during January–June 2022. As of November 2022, dracunculiasis remained endemic in five countries (Angola, Chad, Ethiopia, Mali, and South Sudan).

What are the implications for public health practice?

With only 15 human cases identified in 2021 and three during January–June 2022, program efforts appear to be closer to reaching the goal of eradication. However, dog infections and impeded access because of civil unrest and insecurity in Mali and South Sudan continue to be the greatest challenges for the program.
