Pinworms are a common intestinal parasite infection caused by a small white intestinal worm about the length of a staple. While an infected person sleeps, female pinworms leave the intestines through the anus and deposit eggs on the surrounding skin.

Symptoms

There may be slight rectal itching, disturbed sleep and irritability. Most symptoms are mild and many infected people have no symptoms.
