Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2
Abstract
Schistosomiasis is considered as the second parasitic disease responsible for morbidity and mortality. The disease in prevalent in several tropical and subtropical regions with sub-Saharan Africa being among the highest endemic areas. In Sudan, the disease has been determined since the early twentieth century and it's prevalence has been increasing with the extension of irrigated agricultural schemes all over the country. This study aimed to determine the prevalence of intestinal and urinary schistosomiasis in two areas in Sudan: Alkalkla area in Khartoum State near the White Nile and Halfa Algadida, Kassala State, near Atbara River. This cross sectional laboratory based study was conducted between March to October 2011. Seven-hundreds and seventy stool specimens and 770 urine specimens were collected from 720 inhabitants of the both study areas and 50 healthy controls. Samples were investigated by Kato-Katz method and sedimentation technique for stool and urine samples, respectively. The intensity of infection was determined for each subject. The results obtained showed an overall prevalence of 14.5% for Shistosoma. mansoni and 0.4% for Schistosoma. haematobium. Moreover, S. mansoni was found only in Halfa and S. haematobium was found only in Khartoum. The intensity of infection was variable among the study subjects and several factors were found associated with the positive cases including sources of drinking water, history of water contact, level of education and the knowledge about the disease. The study concluded that reduction of water contact and knowledge about the disease are positively acting towards the reduction of disease prevalence in endemic areas. -----------------------------------------------------------------------------------------------------------------
