Circumstantial epidemiology of Schistosoma mansoni in the West-Nile district of Uganda: results of a cross-sectional study in the Rhino Camp area.

A cross-sectional survey of Schistosoma mansoni was undertaken at the Rhino Camp of the West-Nile district of Uganda to establish baseline data for subsequent studies intended to compare this area (a low transmission area) with Pakwach area (high transmission). An overall prevalence of 37% of S. mansoni infection was demonstrated. There was no statistically significant difference in prevalence between males and females. Six per cent of all cases were heavily infected (400 eggs g-1 of faeces). There was no statistically significant difference in prevalence between those with pit-latrines and those with no conventional method of excreta disposal.
