The study was conducted in Selected Rural Communities of Mecha District and Bahir Dar Town Administration, West Gojjam, Northwestern Ethiopia, to determine the prevalence and intensity of human schistosomiasis. A total of 490 stool and urine specimens were collected using stool cup and test tubes respectively. The overall prevalence and intensity of Schistosoma mansoni was 10.4% and 128.03 eggs per gram of stool (EPG) respectively. The prevalence of infection ranging from 7.8% in Wotet Abay Peasant Associations to 12.9% Kudmi Peasant Associations. The prevalence of Schistosoma mansoni infection among males and females was 13.2% and 7.5%, respectively, and the intensity of infection was 132.37 EPG and 120.42 EPG, respectively. The prevalence of Schistosoma mansoni infection among different age groups ranging from 3.9% in ≥ 30 years to 20.5% in 10-14 years whereas, the intensity of infection was ranging from 89.47 EPG in ≥ 30 years to 168.22 EPG in 10-14 years. It signifies the fact that the age groups 10-14 and 15-19 years are the highest risk groups. It is recommended that to control schistosomiasis in the areas should target at the youngest segment of the population.
