Prevalence of Schitosomiasis in Ommahani Village (White Nile Province)

Abstract

This cross-sectional study was carried out in Ommahani village in White Nile Province (WNP) during December 2008. The study aimed to determine the prevalence of Schistosomiasis. In this study, stool samples were collected from 200 participant (118 males and 84 females) and urine samples from 200 participant (104 males and 94 females) at age between 6-60 years were collected. The participant were categorized according to age group as follows, (6-16), (17- 27), (28-38), (39-49) and (50 years and above). The stool samples were processed using kato-katz technique, while the urine samples were examined by ordinary sedimentation technique. The overall prevalence of urinary (Schistosoma haematobium) and intestinal (Schistosoma mansoni) schistosomiasis were found to be 10.5%, with 21 positive samples and 0% with no positive samples respectively. For the positive cases of S. haematobium, the age group (6-16 ) had the highest disease prevalence 12/21 (57.1%). From these , 19 (90.5%) were males while 2 ( 9.5%) were female. S.haematobium egg intensity was found significantly higher in the age group (6-16) years, mean (7 egg/10ml) and also higher in males than in females, mean (5.73 egg/10ml). Statistical analysis showed significant correlation between the egg intensity and clinical feature (haematouria), clinical feature (haematouria) and hatching test, and between the egg count and hatching test. It was concluded that mass treatment by Praziquentel lead to a significant decrease in the disease prevalence as previous studies from the same area revealed higher prevalence.
