In sub-Saharan Africa, the effect of neglected tropical diseases as a group is comparable to that of malaria and tuberculosis.

For example, praziquantel for schistosomiasis costs about US $0.20 per child per year. [6]
S. haematobium is a digenetic trematode found in Africa and the Middle East. It is the major agent of schistosomiasis, the most prevalent parasitic infection in humans. [10] It is the only blood fluke that infects the urinary tract, causing urinary schistosomiasis, and is the leading cause of bladder cancer (only next to tobacco smoking).
