Schistosomiasis, also known as bilharziasis , is caused by parasitic worms. Infection occurs in people when they come in contact with certain parasites such as Schistosoma mansoni, S. haematobium, and S. japonicum. These parasites may be present in contaminated fresh water and the snails that live in it.
Symptoms for schistosomiasis surface within days after the infection and continue till months. Note that the symptoms are caused by the body’s reaction to the eggs produced by worms, not by the worms themselves. Below are the signs and symptoms of schistosomiasis:
