Pinworms are half an inch long or smaller.Pinworms are tiny white worms that are visible to the naked eye. They infect the intestines. Pinworms are generally harmless. They do not cause serious health problems. Your child can easily be treated with medication.
Pinworms spread through the transfer of very tiny pinworm eggs. Contamination can occur if an infected person doesn’t wash his or her hands well after having a bowel movement or after touching the anus or buttocks. The eggs can remain on the person’s nails and hands and can be transferred to any object he or she touches. You or your child can become infected by touching a contaminated item, then swallowing the eggs.

The doctor will ask about your child’s symptoms and health history. The doctor will also examine your child.
You may be asked to do a tape test. This involves applying the sticky side of transparent or cellophane tape to the skin around your child’s anus. The piece of tape is removed and checked for the presence of worms. The doctor may give you a tape test kit, or you can buy one at a drugstore.
Medication is prescribed for your child. All household members may also need to take the medication to prevent pinworms from spreading. Itching and other symptoms should go away within a week.
