Abstract: Studies on urinary scistosomiasis and its snail vector was undertaken. Of the 1,564 urine specimens examined, 472 (30.2%) comprising 312 (66.1%) males and 160 (34.0%) females were infected, with visible haematuria as their predominant presenting symptoms. Among the infected, 331 (70.1%) were excreting under 100 eggs per 10ml urine while 132 (28.0%) and 9 (1.9%) were excreting 10,500 and above respectively. Statistical analysis revealed the intensity of the infection to be significantly higher (p<0.01) in persons under 20 years than in persons above 20 years, while significant variation (p<0.01) in incidence was recorded among different villages, sex, age and occupational groups. The snail intermediate hosts collected during routine malacological survey include Bolinus globosus, B. truncatus, Lymnaca matalensis and Melanoides tuberculata. Of those snails, only B. globosus was found infected with cercariae believed to be human schistosomes.
