Schistosoma is a genus of trematodes, commonly known as blood flukes. These parasitic worms live in the bloodstream of humans and other mammals, causing schistosomiasis. Unlike other trematodes, they don't require a second intermediate host beyond snails. Infection occurs when skin comes into contact with contaminated freshwater. Think of them as tiny, stealthy invaders who sneak into your bloodstream for a free ride 😈. They're the ultimate hitchhikers!
