Abstract



This study has determined the prevalence and intensity of geohelminth infections and the effect of some epidemiological factors on their distribution in Oba Ile, Osun State, Nigeria. The study was conducted between November 2004 and March 2005. Of 489 school children examined, 76.9% harboured Ascaris lumbricoides while 54.6% and 29.2% had hookworm and Trichuris trichiura respectively. The prevalence and intensity of all the three species of geohelminths significantly (p<0.001) varied with age and sex of pupils, with peaks prevalence and intensity occurring in the 6-10 years' age-group. A co-infection of A. lumbricoides and hookworm was the commonest (58.6%) multiple infection. Statistical analysis showed that walking barefoot was the only risk factor for hookworm infection at regular (OR 4.39, 95%CL 2.59-7.45, p<0.001) and occasional levels (OR 2.24, 95% CL 1.16-4.30, p<0.016) while licking of fingers and drinking from hand-dug well, or surface tank were high risk factors for A. lumbricoides and T. trichiura infections. Geophagous pupils were at significantly increased risk of having the three species of geohelminths at both regular and occasional levels.

Keywords: geohelminths, prevalence, intensity, infection determinants.
