Effects of Water Source, Sanitation and Hygiene on the Prevalence of Schistosoma mansoni among School Age Children in Jawe District, Northwest Ethiopia

Abstract

Background: Intestinal schistosomiasis is a disease caused by infection with one of the blood flukes called Schistosoma mansoni. The distribution of Schistosoma mansoni infection is high in Sub-Saharan Africa due to water source, sanitation and hygiene problems. This study aimed to determine the effect of water source, sanitation and hygiene on the prevalence of schistosomiasis among school-age children in Northwest Ethiopia.

Methods: A cross-sectional study was conducted from Apr 2016 to Aug 2016. Children were selected by systematic random sampling and Formol Ether Concentration Technique (FECT) was used to identify Schistosoma mansoni infection. Statistical analysis was done using descriptive statistics and strength of association of schistosomiasis with determinant factors was calculated by bivariate analysis.

Results: Among 333 children, 7% were infected with Schistosoma mansoni. Using surface water for drinking, poor hand wash habit and latrine utilization were significantly associated (P<0.05) with Schistosoma mansoni infection.

Conclusion: Absence of safe water for bathing, washing and swimming, poor sanitation and hygiene practices were major risk factors for schistosomiasis. Therefore, health education should be given on the transmission of S. mansoni infection, pure water, sanitation and hygiene in S. mansoni endemic areas.
