Guinea worm (Dracunculiasis) eradication: update on progress and endgame challenges.

Area of Science:

• Global health
• Infectious disease control
• Parasitology

Background:

• Dracunculiasis, or Guinea worm disease, is a debilitating parasitic disease targeted for global eradication.
• The International Commission for the Certification of Dracunculiasis Eradication (ICCDE) convenes to assess eradication progress.
• WHO and The Carter Center play key roles in monitoring and reporting on dracunculiasis eradication efforts.

Purpose of the Study:

• To review the global progress of dracunculiasis eradication efforts.
• To certify countries that have achieved transmission-free status.
• To identify remaining endemic countries and challenges in the eradication program.

Main Methods:

• Review of reports from international certification teams on dracunculiasis transmission.
• Assessment of program status presented by WHO and The Carter Center.
• Discussion of epidemiological data, including unusual transmission patterns.

Main Results:

• Cote d'Ivoire, Niger, and Nigeria were reported as transmission-free and recommended for certification.
• Somalia and South Africa were certified as free of dracunculiasis transmission.
• Chad, Ethiopia, Mali, and South Sudan were identified as remaining endemic.
• South Sudan reported a 78% decline in cases in 2013.
• Dracunculiasis in dogs was reported in Chad, highlighting complex epidemiology.

Conclusions:

• Several African nations are nearing or have achieved dracunculiasis eradication.
• Continued vigilance and targeted interventions are necessary in endemic regions.
• The emergence of animal reservoirs, such as in Chad, presents new challenges for eradication.
