angiostrongyliasis /an′jē·ō·stron′ji·lī′ə·sis/ , infection by a species of Angiostrongylus. Infection comes after eating contaminated raw or insufficiently cooked hosts such as snails, slugs, prawns, or crabs. Most cases occur in Southeast Asia and the Pacific Basin. A. costaricensis causes abdominal or intestinal angiostrongyliasis. Abdominal cases have been reported in Costa Rica and occur most commonly in young children. A. cantonensis larvae migrate to the central nervous system and cause eosinophilic meningitis.
