Dracunculiasis eradication: aggressive vector control to accelerate interruption of transmission

29 May 2017 | Geneva −− The World Health Organization (WHO) has called on countries where dracunculiasis (guinea-worm disease) is endemic to expand the treatment of all water bodies with the cyclopicide, temephos.

Application of temephos in surface water is known to kill the water fleas (cyclops) that carry the infective guinea-worm larvae.
WHO’s call comes as the world enters the “last mile” in eradicating the first parasitic disease of humans. Until the end of April, only four human cases have been reported to WHO.

The decreasing number of dracunculiasis (guinea-worm disease) infections in dogs in Chad indicates that enhanced control and surveillance measures, supported by a robust education campaign, are working.

The World Health Organization recommends that control measures should be combined with treatment using cyclopicide of all water bodies surrounding affected villages and neighbourhoods.

22 August 2016 | Geneva −− The number of confirmed human cases of dracunculiasis (guinea-worm disease) rises to 11 with 5 cases reported from Chad – the highest number so far from a single country endemic for the disease. Chad has also seen a significant increase in the number of dogs infected with the worm.
In South Sudan, surveillance activities have continued in almost all endemic villages despite safety concerns by the country’s Guinea-Worm Eradication Programme although the recent escalation of the conflict there remains a major concern.

14 June 2016 | Geneva −− Kenya and Sudan have announced they will formally request WHO to verify interruption of transmission of dracunculiasis (guinea-worm disease) in September and November 2016, respectively.

Both former endemic countries have reported zero cases during the past 3 years and are currently in the precertification phase.

WHO is the only organization mandated to certify countries as free of guinea-worm disease.
