Abstract
Studies on urinary schistosomiasis and its snail vector were 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 10 ml 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 the routine malacological survey include Bulinus globosus, B.
truncatus, Lymnaea natalensis and Melanoides tuberculata. Of those snails, only B. globosus was found
infected with cercariae believed to be human schistosomes
