Human intestinal parasites in primary school children in Kampala, Uganda.

A cross sectional survey on intestinal parasite infections was carried out in 5,313 pupils between the ages of ten and fifteen years in 98 primary schools in Kampala. The aim was to identify the types and distribution of intestinal parasites and to estimate the prevalence in school children. Trichuris trichiura (28%), Ascaris lumbricoides (17%) and hookworms (12.9%) were common infections among the children. Other less commonly found parasites were S.mansoni, Strongyloides stercolaris, Taenia sp, Enterobius vermicularis, Giardia lamblia, Entamoeba coli and E. histolytica. Refuse dumps are probably a significant source of transmission of intestinal helminthic infections in Kampala.
