Guinea worm cases fall to ten worldwide, an all-time low

The Carter Center has reported ten human cases of guinea worm disease worldwide in 2025, the lowest number since records began. Four were in Chad, four in Ethiopia and two in South Sudan, down from 15 cases in 2024. The disease infected an estimated 3.5 million people a year across 21 countries when the eradication campaign started in 1986. There is still no vaccine and no drug treatment; the decline has come from filtering drinking water, treating ponds and case-by-case surveillance.
