Trichinosis symptoms, causes, diagnosis, treatment

Trichinosis (trik-ih-NO-sis), sometimes called trichinellosis, is a type of roundworm infection. Roundworms are parasites that use a host body to stay alive and reproduce. Trichinosis occurs primarily among meat-eating animals (carnivores), especially bears, foxes and walruses. Trichinosis infection is acquired by eating larvae in meat.

When humans eat undercooked meat containing trichinella larvae, the larvae mature into adult worms in the intestine over several weeks. The adults then produce larvae that migrate through various tissues, including muscle. Trichinosis is most widespread in rural areas throughout the world. In the United States, it’s most commonly found in hog-producing regions.

Trichinosis can be treated with medication, though it’s not always necessary. It’s also easy to prevent.

Symptoms

Possibly no signs or symptoms
Mild cases of trichinosis — those with only a small number of parasites in your body — may cause no symptoms. Symptoms can develop with moderate or heavy infestation, sometimes progressing as the parasite migrates through your body.

Initial signs and symptoms
You swallow trichinella larvae encased in a cyst. Your digestive juices dissolve the cyst, releasing the parasite into your body. The larvae then penetrate the intestine, where they mature into adult worms and mate. At this stage, you may experience: Continue reading Trichinosis symptoms, causes, diagnosis, treatment
