Prevalence and Molecular Identification of Human Schistosomiasis With Assessment of Associated Epidemiological Risk Factors in Assiut Governorate, Egypt

Schistosomiasis remains one of the most important parasitic diseases of public health concern, particularly in developing countries including Egypt. It is caused by a trematode worm (blood flukes) of the genus Schistosoma

Detailed Description

Schistosomiasis has been diagnosed in Egypt since pharaonic times (3200 B.C.) by recovering Schistosome eggs and antigens in ancient mummies.In Egypt, Schistosoma mansoni and Schistosoma haematobium have historically been highly endemic, with widespread distribution along the Nile Delta and Valley.(4) Schistosoma haematobium is responsible for urogenital schistosomiasis, with hematuria as its primary manifestation, while Schistosoma mansoni, the prevalent species in Egypt, is causing intestinal schistosomiasis with liver-related sequelae
