Abstract: This study was conducted in El Seyal Agricultural Scheme; northern El Matama / River Nile State in order to assess the current situation of bilharzasis and to determine the ecological, behavioural and other factors associated with the prevalence and intensity of the disease. A sample of 350 school children were selected randomly. Questionnare was used for data collection, by direct interviewing of study population. Laboratory investigation were carried to confirm the existence of Bilharziasis infection. The collected data analyzed by computer using the statistical package for social sciences (SPSS for MS Windows release 5.0). The prevalence and intensity of S. HAEMATOBIUM which was the only detected species were very high, that about 11.5 percent of the selected children were infected with a mean intensity of about 50.7 eggs/ 10ml urine. Prevalence and intensity were not following the usual pattern and their association tested by correlation coefficient shown negative result. The distribution an intensity infection varied among different schools in the scheme. The differences in distribution and intensity of infection might be associated mainly to extensive contact with contaminated water. 87.5 percent of the infected children were found to be closely in contact with canals water, with a mean intensity of infection 64.7 eggs/10 ml of urine. In addition to contact with canals water, the study concluded that distribution and intensity of S. HAEMATOBIUM infection were significancely influenced by demographical, behavioural, ecological factors, knowledge about the disease, its transmission and protection against infection..
