Type of disease: Rare conditions
Anisakiasis is a disease caused by an infection of anisakid worms that invade the walls of the stomach or gastrointestinal tract of humans. Transmission occurs when an individual ingests raw or undercooked fish or squid that contains anisakid worm larvae. Symptoms include stomach pain, nausea, vomiting, diarrhea, blood in stool, and mild fever. Affected individuals may also develop severe allergic reactions, including hives, swelling around the face, itching, and, in severe cases, difficulty breathing. Infection may resolve without treatment but antiparasitic medications or surgery may be required.
