Schistosomiasis
Schistosomiasis, also known as bilharzia, is a parasitic disease caused by Schistosoma worms. It spreads through contact with freshwater contaminated by infected snails, leading to chronic illness if untreated.
What is Schistosomiasis?
Schistosomiasis is a waterborne disease primarily found in tropical and subtropical regions. It occurs when parasitic larvae penetrate human skin during activities like swimming or wading in contaminated water. Once inside the body, the parasites mature in the blood vessels, causing organ damage over time. Schistosomiasis is a leading cause of chronic illness in endemic areas, affecting millions of people worldwide.
