History. The history of such an important disease as schistosomiasis involves a great number of observations, events, and individuals; a detailed account of the history is given by Grove , and there are shorter accounts by Foster , Goodwin , and Hoeppli . Egypt has the world's highest hepatitis C infection rate, and the infection rates in various regions of the country closely track the timing and intensity of the anti-schistosomiasis campaign. [14][18] Bladder cancer diagnosis and mortality are generally elevated in affected areas; efforts to control schistosomiasis in Egypt have led to decreases in the bladder cancer rate. In children schistosomiasis can cause anaemia, stunting and a reduced ability to learn. [39], Many countries are working towards eradicating the disease. The morbidity control strategy focused on synchronous chemotherapy for humans and bovines and the new strategy developed in 2004 intervenes in the transmission pathway of schistosomiasis, mainly including replacement of bovines with machines, prohibition of grazing cattle in the grasslands, improving sanitation, installation of fecal-matter containers on boats, praziquantel drug therapy, snail control, and health education. History of schistosomiasis Bilharzia or schistosomiasis is more insidious that sleeping sickness, for it is a debilitating disease rather than a killer. When 20 to 50 percent of children have bloody urine, only school-age children are treated. Schistosomiasis is a snail-borne disease caused by worms of the genus Schistosoma. Content by Isabel Jones. [10] Diagnosis is by finding eggs of the parasite in a person's urine or stool. Quantification is possible by using filtration through a nucleopore filter membrane of a standard volume of urine followed by egg counts on the membrane. Case history #2. [20] Severe disease can lead to narrowing of the colon or rectum. Schistosomiasis is a chronic parasitic infection caused by flukes of the genus Schistosoma.The infection is acquired through contact with infective cercariae in fresh water (e.g. For example, in S. haematobium and S. intercalatum it is snails of the genus Bulinus, in S. mansoni it is Biomphalaria, and in S. japonicum it is Oncomelania.

S. mansoni is found in parts of South America and the Caribbean, Africa, and the Middle East; S. haematobium in Africa and the Middle East; and S. japonicum in the Far East. [23], The worms of S. haematobium migrate to the veins around the bladder and ureters. Three other species, more localized geographically, are S. mekongi, S. intercalatum, and S. guineensis (previously considered synonymous with S. intercalatum). Schistosomiasis is due to immunologic reactions to Schistosomaeggs trapped in tissues. This disease is spreading in first world countries as an STD. The etiology of schistosomiasis in humans was first discovered in 1851 by the German physician Theodor Bilharz. It assisted the Ministries of Health and Education to deliver treatment for schistosomiasis and soil-transmitted helminthiasis in 6 countries, targeting school-age children and adults at high risk of infection. [62], Estimates regarding the number of deaths vary. There is evidence that osteoporosis has affected people for thousands of years. Symptoms include abdominal pain, diarrhea, bloody stool, or blood in the urine. [34], Microscopic identification of eggs in stool or urine is the most practical method for diagnosis. Worldwide, human schistosomiasis remains a serious public health problem, threatening ∼800 million people in 78 countries with a loss of 70 million disability-adjusted life years. [5] The urinary tract or the intestines may be infected. Schistosomiasis is named for the genus of parasitic flatworm Schistosoma, whose name means 'split body'. The parasites that cause schistosomiasis live in certain types of freshwater snails. The name Bilharzia comes from Theodor Bilharz, a German pathologist working in Egypt in 1851 who first discovered these worms.
