Schistosomiasis is caused by which type of parasite?

Explanation:
Schistosomiasis is caused by trematodes, the fluke worms. These flatworms—multicellular parasitic worms—live in the human circulatory system as adults and lay eggs that trigger tissue inflammation. Their life cycle also involves freshwater snails as intermediate hosts. This distinguishes them from other parasite types: roundworms (nematodes) are elongated cylindrical worms, tapeworms (cestodes) are flat but have a different body structure with a scolex and proglottids, and protozoa are single-celled organisms. So the parasite type linked to schistosomiasis is the fluke worm.
