Pork tapeworm disease; cysticercosis and neurocysticercosis

Parasitic Diseases, Cestodes (Tapeworms)

Animals Involved

People are definitive host; swine, occasionally other mammals, including people, are intermediate hosts

Known Distributions

Worldwide where swine are reared; most cases seen in Africa, Asia, Central and South America

Probable Means of Spreading

Ingestion of undercooked pork containing larvae causes taeniasis; ingestion of eggs (including autoinfection from adult worm in intestine) causes cysticercosis

Clinical Manifestations in People

Adult stage in intestine (taeniasis) mild or asymptomatic; cysticercosis usually asymptomatic for years until cysticercus becomes large or death of small cysticerci result in inflammation in CNS (seizures, other CNS signs) or infrequently in eye or heart; massive numbers in muscles can also be symptomatic
