PY - 2023 T2 - Current Medical Diagnosis & Treatment 2023 AB - Eight species of Paragonimus lung flukes cause human disease. The most important is Paragonimus westermani. Paragonimus species are endemic in East Asia, Oceania, West Africa, and South America, where millions of persons are infected; rare infections caused by Paragonimus kellicotti have occurred in North America. Eggs are released into freshwater, where parasites infect snails, and then cercariae infect crabs and crayfish. Human infection follows consumption of raw, undercooked, or pickled freshwater shellfish. Metacercariae then excyst, penetrate the peritoneum, and pass into the lungs, where they mature into adult worms over about 2 months (eFigure 35–26).
