Adult tapeworm infection is the infection of the digestive tract by parasitic flatworms called cestodes or tapeworms. Tapeworm larvae are sometimes ingested by consuming undercooked food. Once inside the digestive tract, the larva grows into an adult tapeworm, which can live for years and grow very large. Additionally, many tapeworm larvae cause symptoms in an intermediate host. For example, cysticercosis is a disease of humans involving larval tapeworms in the human body.
