Taeniasis and cysticercosis

Teniasis is an intestinal infection with an adult worm. Cysticercosis corresponds to larvae in tissues after ingestion of Taenia solium eggs.

Documentary Enrichment: · General information

Essentials

Tenasis follows the ingestion of pigs containing larvae; cysticercosis follows the ingestion of eggs of the parasite by the fecooral route.

Agent
Taenia solium
Transmission or exposure
Water and food · Animal / zoonosis · Close contact

Situation and vulnerability

Cysticercosis can affect a person who does not eat pork if it ingests eggs through faecoral contamination. The consequences depend in particular on the organs affected.

Signs and limits of their interpretation

Teniasis can give little digestive evidence. Neurocysticercosis may occur through seizures, headaches or visual disturbances, sometimes after a long silent period.

Diagnosis and monitoring

Convulsive crisis should be evaluated quickly. The distinction between intestinal worm and tissue cysts is essential for organizing examinations and treatment.

Prevention and care

Meat cooking, hand hygiene and sanitation work at different stages of the cycle. Neurocysticercosis requires specialized care: destroying cysts can cause inflammation.

Practical issues

Does eating uncooked pork directly give a cysticercosis?

Pork containing larvae transmits teniasis to T. solium. Cysticercosis comes from ingestion of its eggs: both situations and their treatments must be distinguished.

Preparing for an exchange with a professional

  • Residence places and food exhibitions
  • Crises, headache and visual disorders
  • Previous imaging and pest treatments

Individual decisionThe choice of a test, treatment or prevention depends on the local situation and recommendations. In case of distress, call 911.
