How is intestinal fluke transmitted?
Humans (and pigs) pass eggs in their feces, which develop in water and infect snails as intermediate hosts. After further development, the parasites leave the snail intermediate host and encyst on water plants. Humans become infected as a result of eating these contaminated water plants raw (or undercooked).
