Paragonimiasis; Life cycle
Human acquire the fluke by ingesting larvae in law or incompletely cooked crustarceans, mainly crayfish and crabs
Metacarcariae hatch in the human duodenum and pass through the bowel wall into the peritoneal cavity through diaphragm pleural cavity lung parenchyma mature in about 70 days and lodge near the bronchioles and bronchi deposit their ova discharge into the bronchial lumen with blood and inflammatory debris some expectroated and others swallowed passed in the feces miracidia infect freshwater snails, genus Melania
