Assessment of two Techniques Used in Diagnosis of Urinary Schistosomiasis and The Prevalence of The Disease among School Pupils in Dar alslam – Khartoum State

Abstract

This study was conducted in Dar alslam, East of Khartoum. The study was conducted on 500 individuals comprising different genders and age groups. Two technique were used in this study; centrifugation technique for all studied individuals and ELISA technique for 50 of the positive cases detected by centrifugation technique and 50 of the negative cases as well. The results revealed that out of 500 urine samples examined by the centrifugation technique, 61pupils were found to be positive for S.haematobi-um infection constituting an overall prevalence rate of 12.2%. Out of 420 males examined, 58 males were found positive for S.haematobium infection and out of the 80 females examined, 3 females were found positive. This constitutes 13.8% and 3.8% prevalence rate respectively. The highest prevalence rate (14%) was reported among the 12 – 17 age groups, while the lowest rate (7.9%) was reported among the 18 – 22 age groups. The result showed that the prevalence rate was 32.3% for those who had contact with water, while it was 1.5% for those who had no contact with water. The result showed that the prevalence rate was 28.9% among those with a history of previous infection compared to the 8.5% rate for those with no previous schistosoma infection. For those who received treatment, the prevalence rate was 22% compared to the 10.4% rates for those who did not receive treatment. From the result, ELISA test proved sensitivity rate of 88% and specificity rate of 92%.
