Which statement best describes schistosomiasis?

Schistosomiasis is a parasitic disease caused by Schistosoma worms, and it is commonly known as bilharzia in many regions. The name bilharzia comes from Theodor Bilharz, who first described the disease. This naming is the best description here because it identifies a widely used alternative name for the same condition. The other statements aren’t correct: the disease is not caused by bacteria; the parasites spend part of their life cycle in freshwater snails and release larvae that can penetrate human skin, so transmission occurs through skin contact with contaminated water, not through ingestion or other means; and the worms do survive in water environments during parts of their life cycle, so saying they do not survive in water is inaccurate.
