Abstract:A preliminary investigation of the incidence of guinea worm (Dracunculus medinensis) infection was undertaken in the villages of Mafi and Kawaram in Damboa Local Government Area, Borno State, Nigeria, in 1987/1988. The results, based on a random sample of twenty-five families in Mafi and twenty families in Kawaram, indicate high rates of guinea worm infection, viz. 42 percent and 45.7 percent respectively. These infection rates are higher than those estimated for the year 1986/1987 in both villages. Individuals within the productive age group of 16-35 years appeared to run the highest risk of infection, while the lowest infection rate occurred among the under 16. Parasites were aggregated or overdispersed with variance to mean ratios of 2.34 for Mafi and 1.48 for Kawaram. Possible foci of infection include ponds, shallow wells and streams that provide drinking water for the human population. Living organisms in these foci included cyclopoid copepod vectors of guinea worm, cladocerans (Daphnia), and ostracodans. The cyclops were most abundant in November/December. Their population dropped slightly in January/February, but increased again in May/June. Dissection and microscopical examination of these vectors did not reveal the presence of any juvenile nematodes. Bibliogr., sum.
