ABSTRACT
Aims:This study aimed at determining the prevalence, infection intensities and risk factors associated with Schistosomiasis (SCH) and Soil transmitted helminthiasis (STH) among school aged children (SAC) in Tiko Health District (THD). Study Design: A community-based cross-sectional study was conducted in three health areas (Likomba, Holforth and Tiko town) in Tiko Health District.Place and Duration of Study: The study was carried out in THD from July to October, 2018.Methodology:The study included 464 children of both sexes aged between 4 –15 years. Stool and urine samples were collected from 464 children and processed using the Kato Katz and Urine filtration techniques respectively. Information on socio-demographic characteristics and risk factors were collected using structured questionnaires. Data was analyzed using SPSS version 25 with statistical significance set at p< 0.05.Results:Of the 464 SAC examined, the overall prevalence of Schistosomiasis, STH and Schistosomiasis/STH co-infection rate in THD was 16.16%, 14.44% and 0.43% respectively. Females (18.98%; 14.81%) were more infected with Schistosomiasis when compared to STH than males (13.71%; 14.11%). The order of STH prevalence observed was Ascariasis (9.27%) > Hookworm disease (3.88%) > Trichuriasis (1.29%). The mean infection intensity for Urinary Schistosomiasis and STH was 4.36 eggs per 10ml and 11.74 eggs per gram (EPG) respectively. SAC residing in Likomba HA were significantly at higher risk of Schistosomiasis (aOR: 4.40, P=0.008) and STH (aOR: 2.14, P= 0.031). Use of tap water was associated with STH.Conclusion: Tiko Health District can be considered as a moderate-risk zone for Schistosomiasis and a low risk zone for STH infection according to WHO classification
