Effects of water sanitation and hygiene (WASH) education on childhood intestinal parasitic infections in rural Dembiya northwest Ethiopia: an uncontrolled before-and-after intervention study

摘要

BackgroundSoil-transmitted helminthes (STH) infections are among the most common infections worldwide and affect the most deprived communities. Adequate water, sanitation, and hygiene (WASH) prevents environmental contamination, thereby preventing transmission of STH. Cognizant of this, WASH education was implemented in rural Dembiya to reduce intestinal parasitic infections. This study was, therefore, conducted to assess the impacts of the intervention on households’ WASH conditions and prevalence of intestinal parasitic infections.
