Schistosomiasis
What is it?
Schistosomiasis, also known as bilharzia, is caused by a parasitic fluke – a type of flatworm. The infection is contracted by bathing in contaminated fresh water.
The parasite’s eggs get into water from human urine or faeces and develop within the body of a freshwater snail. In the next stage of their life cycle, the parasites leave the snail and enter the human body by burrowing through the skin and entering the bloodstream. They then migrate to the liver and spread from there to the bladder or bowel, where they mate and produce eggs, which are excreted in urine or faeces.
What does it do(Schistosomiasis symptoms)?
Some people may develop a swimmer’s itch where the schistosoma enters the body, but in most cases there are no initial symptoms. Later, however, an infected person may develop coughing, diarrhoea, weight loss, blood in the urine, headaches, joint and muscle pain and enlargement of the liver and spleen. If the infection persists it can cause liver damage, bladder damage and kidney problems.
Where is it ?
The infection arises mainly in sub-Saharan Africa, southern China, the Philippines and Brazil. Lake Malawi in Africa is particularly renowned for the disease.
Schistosomiasis treatment?
There is an antibody test to confirm infection. The disease requires specialist treatment by tropical disease units.
Can it be prevented?
There is no vaccine, but the disease can be prevented by avoiding swimming in rivers or lakes. Chlorine and salt water both kill flukes, so swimming pools and seawater are safe.
