Abstract: An epidemiological investigation to determine, the prevalence of urinary schistosomiasis parasite Schistosoma haematobium was conducted among children aged between 5-14 years from 15 January to 25 February 2010 in 10 public primary schools in the town of Maroua Head instead of the region of Far North Cameroon. A sample of 620 students responded to a questionnaire previously developed and these same students were subject to urine samples. The examination of urinary sediment under the microscope revealed an overall prevalence of 22.90% of bladder bilharziasis with Schistosoma haematobium. The age group most heavily infested was that of 9-11 years (36.40%) and less affected than 6-8 years (14.70%).
