A cross- sectional study was carried out during the period between March to June 2011. A total number of 519 inhabitants from different villages in New Halfa city were included in this study. Stool samples were taken from all the study subjects. Epidemiological and parasitological data were obtained and recorded. Out of 519 stool samples, 112 (21.5%) were positive for S.mansoni by using direct wet mount by examining 3 slides preparation for each sample and Kato-Katz technique respectively. The study reflected that the two methods direct wet mount by examining 3 slides preparation and Kato technique showed highly significant differences (p=0.000). Regarding the gender and age groups, the current study showed that the difference in prevalence rate was found to be statistically significant at p. value=0.000. This study indicated that the study area is highly endemic for intestinal schistosomiasis and the prevalence rate of S.mansoni infection is reflecting high.
