Schistosomiasis, also known as snail fever, bilharzia, and Katayama fever, [1] [2] [9] is a disease caused by parasitic flatworms called schistosomes. [5] The urinary tract or the intestines may be infected. [5] Symptoms include abdominal pain, diarrhea, bloody stool, or blood in the urine. [5]
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]
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), with hundreds of millions infected worldwide.
Symptoms of all forms of schistosomiasis are caused by the immune system's reaction to the eggs, rather than the adult worms themselves. [5] A few hours to days after cercariae invade the skin, some people experience pruritus and raised papules at the site of penetration. This is called cercarial dermatitis, also known as swimmer's itch.
These symptoms negatively impact nutritional status, including decreased absorption of micronutrients, loss of appetite, weight loss, and intestinal blood loss that can often result in anemia. It may also cause physical and mental disabilities, delayed growth in children, and skin irritation around the anus and vulva.
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 the leading cause of bladder cancer (only next to tobacco smoking). [2] [3] The diseases are caused by the eggs.
The signs and symptoms of helminthiasis depend on a number of factors including: the site of the infestation within the body; the type of worm involved; the number of worms and their volume; the type of damage the infesting worms cause; and, the immunological response of the body. Where the burden of parasites in the body is light, there may be ...
A diagnosis usually can be made by the presenting signs and symptoms alone. If the diagnosis is unclear, a throat swab or stool specimen may be taken. Medications are usually not needed as hand, foot, and mouth disease is a viral disease that typically resolves on its own. Under research [15] [16] Sin Nombre virus: Hantavirus Pulmonary Syndrome ...
