Abstract: Epidemiological study on public health problem of Schistosoma mansoni and soil-transmitted helminthes was carried out between October and November 2007, in 9 primary schools of Adwa town to determine the prevalence, intensity and associated risk factors for S. mansoni and soil- transmitted helminthes (STH). Fecal samples of 386 subjects aged 7-18 years, were examined using Kato-Katz and formol-ether concentration methods. A questionnaire was used to obtain socio-demographic information and associated risk factors for S. mansoni and STH infections. Data was analyzed using the SPSS statistical software. Both Kato-Katz and formol-ether concentration methods done on the 386 stool specimen revealed that 263(69%) had one or more intestinal parasites. S. mansoni infection was the most prevalent (63%), while the prevalence of soil-transmitted helminthiasis was found to be low. The prevalence of A. lumbricoides and hookworm infections were (6.4%) and (1%), respectively, whereas no infection of T. trichiura was found. Other parasites identified in this study were S. stercoralis (0.3%), H. nana (8.1%) and cysts of E. histolytica /dispar (1.8%). S. mansoni and A. lumbricoides were found in all age groups; but with no significant difference among the age groups. Intensity of S. mansoni and A. lumbricoides infection was generally low, except for 5.1% who have high intensity of S. mansoni infection. Double infection was found in 4% of the children. An association was not found between socio-demographic variables and STH infection. However, multiple regressions revealed that male gender (p<0.05, OR=1.72), swimming habit in rainy season (p<0.05, OR=2.12), and water contact while crossing the stream (p<0.05, OR=1.85) were significantly associated with S. mansoni infection. The high prevalence of S. mansoni infection among school children of Adwa town signifies the need for timely control measures in the study area.
