Pinworms are tiny, visible parasites (Enterobius vermicularis) that infect the intestines and rectal/anal areas of humans.
Discomfort and itching in the anal area are the main symptoms of pinworms. Other signs and symptoms associated with pinworms include
- rash around the anus or vagina,
- vaginal itching,
- insomnia or restlessness during sleep due to the irritated skin,
- visible pinworms in the anus, vagina, or on stools, and
- painful urination.
Some people may experience abdominal pain or secondary bacterial skin infections that arise after scratching.
Cause of a pinworm infection
Pinworm infections spread from person to person by ingesting pinworm eggs that have contaminated fingers, bed linens, clothing, or other items. Young and school-aged children are at greatest risk for pinworm infection.
