Taeniasis (taenia saginata)

ICD-10 B68.0: Taenia Solium Taeniasis
ICD-10 B68.1: Taenia Saginata Taeniasis
ICD-10 B69: Cysticercosis
3.14.1 Identification

Beef tapeworm and pork tapeworm.

Case classification:
• Suspect case: Clinical manifestations of infection with the adult worm, if present, are variable and may include nervousness, insomnia, anorexia, weight loss, abdominal pain and digestive disturbances.
• Probable case: In the presence of somatic cysticercosis, epileptiform seizures, headache, signs of intracranial hypertension or psychiatric disturbances strongly suggest cerebral involvement Neurocysticercosis.
• Confirmed case: Infection with an adult tapeworm is diagnosed by identification of proglottids (segments), eggs or antigens of the worm in the feces or on anal swabs. Specific diagnosis is based on the morphology of the scolex (head) and/or gravid proglottids.

3.14.2 Infectious agent

Taenia solium, the pork tapeworm, causes both intestinal infection with the adult worm and extra intestinal infection with the larvae (cysticerci). T. saginata, the beef tapeworm, only causes intestinal infection with the adult worm in humans.

3.14.3 Occurrence

Worldwide; frequent wherever beef or pork is eaten raw or insufficiently cooked and where sanitary conditions are lacking.

3.14.4 Reservoir

Humans are the definitive host of both species. Cattle are the intermediate hosts for T. saginata and pigs for T. solium.
