Schistosoma lives in human body in

• A. Lymph nodes
• B. Urinary tract blood vessels
• C. Mesenteric and hepatic portal veins
• D. All of the above

Answer 1

Answer: (D)

All of the above

Schistosomiasis is an acute and chronic disease caused by blood flukes. People become infected when larval forms of the parasite released by freshwater snails and penetrate the skin during contact with infested water. Transmission occurs when people suffering from schistosomiasis contaminate freshwater sources with their excreta containing parasite eggs, which hatch in water. In the body, the larvae develop into adult schistosomes. Adult worms live in the blood vessels, lymph nodes, mesentric and hepatic portal veins etc. depending on the infected species. So, option D is correct.
