Prevalance of Urinary Schistosomiasis in Al Lamab – Khartoum State Using three Diagnostic Methods

Abstract

This cross sectional study was conducted in AL-Lamab_Khartoum State on 270 (200 males and 70 females) to determine the prevalence rate of Schistosomahaematobiumand to evaluate three diagnostic methods (sedimentation,filteration technique andELISA technique. The study was carried out during the period between August 2013 to December 2013. Urine and blood samples were taken from the subjects. Epidemiological and parasitological were obtained and recorded. The study showed that the overall prevalence rate of infection was 11.1% All positive cases (30) out of 270 were detected by using urine sedimentation and filtration techniques. Males have reported higher rate of infection than females (14% and 2.8% respectively). The highest infection rate (16.4%) was reported among the age group 10-15 years, while the lowest infection rate was reported among the age group>22 year (5%). The study showed that among 30 positive cases, 29 (14.2%) had direct contact with water and 1(1.4%) had no contact with water. Also the study showed that among 30 positive cases 27(90%) had haematuriaand proteinuria in their urine while 3(10%) had no haematouria and proteinuria in their urine. The study indicate that the prevalence rate of S.haematobium11.1% in the study area and urine sedimentation technique more sensitive than filtration technique in diagnosis of infection Only 30 positive samples and 30 negative samples were tested by the ELISA technique. The sensitivity and specificity reported were (90.6% and 96.4% respectively).
