Epidemiological study on public health problem of Schistosoma mansoni and soil-transmittedrnhelminthes was carried out between October and November 2007, in 9 primary schools of Adwarntown to determine the prevalence, intensity and associated risk factors for S. mansoni and soil-rntransmitted helminthes (STH). Fecal samples of 386 subjects aged 7-18 years, were examinedrnusing Kato-Katz and formol-ether concentration methods. A questionnaire was used to obtainrnsocio-demographic information and associated risk factors for S. mansoni and STH infections.rnData was analyzed using the SPSS statistical software. Both Kato-Katz and formol-etherrnconcentration methods done on the 386 stool specimen revealed that 263(69%) had one or morernintestinal parasites. S. mansoni infection was the most prevalent (63%), while the prevalence ofrnsoil-transmitted helminthiasis was found to be low. The prevalence of A. lumbricoides andrnhookworm infections were (6.4%) and (1%), respectively, whereas no infection of T. trichiurarnwas found. Other parasites identified in this study were S. stercoralis (0.3%), H. nana (8.1%) andrncysts of E. histolytica /dispar (1.8%). S. mansoni and A. lumbricoides were found in all agerngroups; but with no significant difference among the age groups. Intensity of S. mansoni and A.rnlumbricoides infection was generally low, except for 5.1% who have high intensity of S. mansonirninfection. Double infection was found in 4% of the children. An association was not foundrnbetween socio-demographic variables and STH infection. However, multiple regressions revealedrnthat male gender (p
