Global Health Migrants One Step Closer to Eradicating Devastating Guinea Worm Disease
For the first time in decades, a significant decline in reported cases of Guinea worm disease has been recorded. In 2025, a mere 10 human cases were documented worldwide, according to the Carter Center's latest update.
When the eradication program began in 1986, there were an estimated 3.5 million cases of Guinea worm disease across 21 countries in Africa and Asia. The parasite was transmitted through contaminated water that contained copepods, tiny crustaceans that harbor its larvae. Infected individuals would later experience excruciating pain as the adult worm emerged from a painful blister on their skin.
The consequences of Guinea worm disease are dire. Apart from causing immense physical suffering, it can also lead to secondary infections and sepsis, resulting in temporary or permanent disability. The disease's impact extends beyond the individual, affecting entire families and communities.
Thanks to concerted efforts by health workers and the Carter Center, however, the tide seems to be turning. Since 1986, the eradication program has estimated to have prevented 100 million cases of Guinea worm disease. In 2024, there were just 15 reported cases, and this year's provisional total stands at a mere 10.
To achieve global eradication, health workers must also focus on eliminating animal cases. In 2025, such cases were detected in Chad, Mali, Cameroon, Angola, Ethiopia, and South Sudan. The eradication program relies on public education campaigns and tools like larvicide to treat contaminated water sources.
While progress has been made, there is still much work to be done. According to Adam Weiss, director of the Carter Center Guinea Worm Eradication Program, "every case is a real person we know by name." With this in mind, it's imperative that health workers redouble their efforts to finish what they started.
Only 10 human cases reported worldwide so far
