Background: Schistosomiasis and Soil-transmitted helminthiasis cause considerable morbidity and mortality in developing countries, especially among children. To this end it, a cross-sectional survey to determine the pattern of Schistosomiasis and Soil-transmitted helminthiasis co-infection was undertaken among primary school pupils in Oduma Community in Enugu State, Nigeria.

Methods: Fresh urine and stool samples were collected from pupils. The urine and stool samples were examined using sedimentation and Kat-Katz techniques respectively.

Results: Of the 236 pupils examined, 137 (58.1%) were found positive for at least one helminth infection. Ascaris lumbricoides was the most prevalent soil-transmitted helminth (STH), with a prevalence rate of 40.3%, followed by Trichuris trichiura (15.3%) and hookworm (8.9%). Infection with Schistosoma haematobium was detected in 13.6% of the pupils while Schistosoma mansoni infection prevalence was 7.2%. Age group 4 -7 years recorded the highest prevalence for S. haematobium, A. lumbricoides, T. Trichiura and hookworm infections. Multiple infections were also recorded, with 22.9% having double infections and 2.5% having triple infections. The most common double infection was A. lumbricoides with T. trichiura (8.9%), while the most common triple infection was A. lumbricoides, S. haematobium and hookworm (1.7%).

Conclusion: The results from the present study revealed an evident need for the systematic and sustained administration of school-based chemotherapy program targeting the control of STH infection and Schistosomiasis using Albendazole and Praziquantel respectively in the community, instead of a one-off approach that was carried out.
