Trichiniasis Overview

Another name for Trichiniasis is Trichinosis.

What is trichinosis?
A person with trichinosis has an infection caused by the roundworm, Trichinella spiralis. Trichinosis is caused by eating undercooked, pork or wild game that contains Trichinella cysts. Round worms form in the intestines and small cysts form in the muscles. Most cases of trichinosis do not cause symptoms. Fortunately, complete recovery is expected without treatment.

What are the symptoms of trichinosis?
The most common symptoms of trichinosis include diarrhea and abdominal pain. Additional symptoms of trichinosis include constipation, abdominal swelling, nausea, headache, muscle aches, fever, fatigue, and a rash that looks like bruises or broken blood vessels under the skin.

How does the doctor treat trichinosis?
Treatment for trichinosis includes antiparasitic medications and oral corticosteroids.
