Schistosomiasis is known as bilharzia or bilharziosis in many countries, after German physician Theodor Bilharz, who first described the cause of urinary schistosomiasis in 1851. [81] [82] The first physician who described the entire disease cycle was the Brazilian parasitologist Pirajá da Silva in 1908.
Clinical symptoms are caused by the eggs. As the leading cause of schistosomiasis in the world, it is the most prevalent parasite in humans. It is classified as a neglected tropical disease. As of 2021, the World Health Organization reports that 251.4 million people have schistosomiasis and most of it is due to S. mansoni. [1]
It is found in Africa and the Middle East. It is the major agent of schistosomiasis, the most prevalent parasitic infection in humans. [1] It is the only blood fluke that infects the urinary tract, causing urinary schistosomiasis, and is a leading cause of bladder cancer (only next to tobacco smoking). [2] [3] The diseases are caused by the eggs.
Schistosoma is a genus of trematodes, commonly known as blood flukes.They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis, which is considered by the World Health Organization to be the second-most socioeconomically devastating parasitic disease (after malaria), infecting millions worldwide.
11-year-old Filipino boy with ascites due to schistosomiasis. There are over 200 million cases of schistosomiasis. [16] Approximately 85 percent of cases are in sub-Saharan Africa. [16] The disease can be fatal by causing bladder cancer and hematemesis. [16] Schistosoma species have a complex life cycle that alternates between humans and ...
Schistosoma japonicum is an important parasite and one of the major infectious agents of schistosomiasis.This parasite has a very wide host range, infecting at least 31 species of wild mammals, including nine carnivores, 16 rodents, one primate (human), two insectivores and three artiodactyls and therefore it can be considered a true zoonosis.
The 1990–2013 Global Burden of Disease Study estimated 5,500 direct deaths from schistosomiasis, [77] while more than 200,000 people were estimated in 2013 to die annually from causes related to schistosomiasis. [78] Another 20 million have severe consequences from the disease. [79] It is the most deadly of the neglected tropical diseases. [80]
Schistosomiasis is an environmentally-acquired trematodiasis accounting for over 200 million cases annually, most of which are in Africa. [10] The urinary blood fluke ( Schistosoma haematobium ), the Southeast Asian liver fluke ( Opisthorchis viverrini ) and the Chinese liver fluke ( Clonorchis sinensis ) are recognised by the International ...
