Long-term disability due to guinea worm disease

Abstract

The village-based surveillance system for guinea worm disease (dracunculiasis), which has been established in all endemic villages in Ghana, was used to carry out a retrospective study of long-term disability due to the disease. A sample of 195 cases was interviewed and examined, 12-18 months after emergence of the worm. Currently continuing pain when walking or working, attributable by its location and date of onset to the episode of dracunculiasis, was reported by 55 persons (28.2%). Some difficulty in performing at least one of 6 everyday physical activities, attributable after careful interview to the episode, was reported by 66 respondents (34.0%), of whom 10 (5.1%) were unable to carry out one of the activities. In one case, the disease had caused impairment of movement of the joints of the right thumb. The prevalence of serious permanent physical impairment among the cases in the study was thus 0.5%.
