The first intermediate host of Paragonimus westermani, a lung fluke, is typically a freshwater snail, often from the genus Oncomelania. The second intermediate host is usually a crustacean, commonly a freshwater crab or crayfish. Humans become infected by consuming undercooked or raw crustaceans harboring the larvae. This fluke can cause significant respiratory issues and other health problems in infected individuals.
