Abstract
The control of schistosomiasis has been hampered by lack of baseline data to demarcate communities at risk for treatment in Ogun State. This study was therefore aimed at implementing a rapid and valid epidemiological assessment of Urinary Schistosomiasis in this state, and help prioritised areas for treatment. Questionnaires were developed, pre-tested and delivered to head teachers of 1,310 state-owned primary schools, with the assistance of Local Government Primary Schools Education Authority (LGEA) respectively. Class teachers conducted interviews. School children were asked among other health problems, if they have passed blood in urine or have urinary schistosomiasis and their responses recorded as yes or no. The completed questionnaires were retrieved to the researches through LGEA within six weeks. Responses were then validated by parasitological examination of randomly collected urine sample in 50 schools for Schistosoma heamatobium eggs. A total of 101, 682 children in classes 4 to 6 were interviewed in 1,092 out of 1,310 primary schools in the state. Questionnaires retrieved rate was 83.4%. the overall mean prevalence of self-reported blood in urine and self-reported urinary schistosomiasis were 10.00%, SD = 13.84 and 7.60% SD = 12.85 respectively. Spearman rank correlation showed a highly significant association between reported blood in urine and urine filtration test (r=0.704; pNigerian Journal of Parasitology Vol. 25, 2004: 111-119
