Soil-transmitted helminth (STH) like roundworms, whipworms, and hookworms, infect humans around the world. Soil samples from selected barangays in Alangalang, Leyte were examined for STH contamination. A total of 100 soil samples from four selected barangays were collected and processed using sucrose centrifugal flotation technique. The results showed that 12% (12/100) of soil samples were contaminated with STH eggs and larvae. STH recovered were hookworm/strongylid (12.0%) and Toxocara (2.0%). The contamination rate was found higher in Binongtoan (20.0%) followed by Ekiran (12.0%), Canvertudes and Hupit with an 8.0% contamination rate ( p = 0.64 ; not significant). Additionally, the mean density among selected barangays was not statistically significant (p = 0.54) Physicochemical parameters specifically soil pH ( r = - 0.018 ; P = 0.86 ), soil temperature ( r = 0.021 ; p = 0.83), and soil texture ( r = 0.22 ; p = 0.092 ) have no significant correlation to STH contamination rate. This study showed that the soil in four selected barangays in Alangalang, Leyte were contaminated with STH, which can contribute to STH infections of the residents. Lago, Catherine B. adviser.
