What is the fluke life cycle?

The fluke life cycle typically involves multiple hosts and stages. It begins with eggs excreted in host feces, which hatch into larvae in water. These larvae then infect a first intermediate host, usually a snail, where they undergo several developmental stages. After leaving the snail, the larvae infect a second intermediate host, like a fish or mammal, where they mature into adult flukes that can eventually infect a definitive host, often a vertebrate, to complete the cycle.
