How is Schistosoma sp most likely transmitted to humans?
The parasites that cause schistosomiasis live in certain types of freshwater snails. The infectious form of the parasite, known as cercariae, emerge from the snail into the water. You can become infected when your skin comes in contact with contaminated freshwater.
What disease does Schistosoma spp cause?

What is the vector of schistosomiasis?
Schistosomiasis (also known as bilharzia) is a vector-borne parasitic disease caused by trematode flatworms of the genus Schistosoma. Freshwater snails act as the vector, releasing larval forms of the parasite into water. These larvae subsequently penetrate the skin of people who are in that water (e.g. fishermen).
What causes urinary schistosomiasis?
Urinary schistosomiasis is caused by S haematobium and deposition of eggs in the bladder and ureters. The subsequent granulomatous inflammation causes nodules, polypoid lesions, and ulcerations in the lumens of the ureter and bladder, which in turn causes urinary frequency, dysuria, and end stream haematuria.
