Notes on our processing step for this indicator
The current and historical values for the status of Guinea worm disease (Dracunculiasis) as certified by the WHO. To be certified as free of guinea worm disease, a country must have reported zero indigenous cases through active surveillance for at least three consecutive years. Data regarding certification status is available at the WHO: https://web.archive.org/web/20211024081702/https://apps.who.int/dracunculiasis/dradata/html/report_Countries_t0.html We have added the recent changes to Guinea worm disease certification: - Angola has had endemic statuss since 2020: https://www.who.int/news/item/23-09-2020-eradicating-dracunculiasis-human-cases-and-animal-infections-decline-as-angola-becomes-endemic - Kenya was certified guinea worm free in 2018: https://www.who.int/news/item/21-03-2018-dracunculiasis-eradication-south-sudan-claims-interruption-of-transmission-in-humans - DRC was certified guinea worm free in 2022: https://www.who.int/news/item/15-12-2022-the-democratic-republic-of-the-congo-certified-free-of-dracunculiasis-transmission-by-who
