Ghana and Nigeria, the two countries with the highest number of known cases of dracunculiasis (i.e., Guinea worm disease) in 1991, recorded substantial declines in the reported incidence of the parasitic infection caused by Dracunculus medinensis. Provisional surveillance data from 1991 indicate that the combined incidence of dracunculiasis declined 32.7% in the two countries since 1990 and 57.5% since 1989 (Figure 1). This report summarizes surveillance data for the two countries.
