Cercaria of blood fluke pass into human body through

• A. Ingestion of food
• B. Drinking of contaminated water
• C. Direct penetration through skin
• D. Both B and C

Answer 1

The correct option is D Both B and C

People become infected when larval forms of the parasite, which are released by freshwater snails 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. Drinking of contaminated water also causes the disease. So, option D is correct.
