Question

Quizplus · Accepted Answer

Schistosomiasis is caused by parasitic flatworms called blood flukes, specifically of the genus Schistosoma. It is contracted by skin contact with contaminated water, as the larvae of the parasite live in certain freshwater snails and are released into the water. When a person comes into contact with the contaminated water, the larvae can enter their body and develop into adult worms that live in the blood vessels around the bladder, intestines, or liver. The disease can cause serious health complications, including chronic pain, organ damage, and increased susceptibility to other infections.
