When Your Child Has Pinworms

How do pinworms spread?

Pinworms spread through the transfer of very tiny pinworm eggs. Contamination can occur if an infected person doesn’t wash their 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 they touch. Eggs can survive 2 to 3 weeks on objects. You or your child can become infected by touching a contaminated item and then swallowing the eggs.

What are the symptoms of pinworms?

• Itching around the anus and buttocks, usually at night

• Vaginal itching in girls

• Mild abdominal (belly) pain (rare)

How are pinworms diagnosed?

• Your child's health care provider will examine your child and ask about your child’s symptoms and health history.

• 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 in the morning before any washing has been done. The piece of tape is removed and checked for the presence of worms or eggs. Your child's provider may give you a tape test kit, or you can buy one at a pharmacy.

How are pinworms treated?

The usual treatment is a single pill taken once when diagnosed and again 2 weeks later. There is also an over-the-counter medicine available. All other household members will also be treated, as they likely are infected as well, even if they have no symptoms. Itching and other symptoms should go away within a week.

How can you prevent the spread of pinworms?

Follow these steps to keep your child from passing pinworms to others:

• Teach your child to wash their hands with soap and water often. Handwashing is especially important before eating or handling food, after using the bathroom, and after scratching the affected area.

• Don't allow your child to share cups, utensils, napkins, or personal items, such as towels and toothbrushes with others.

• Keep your child’s hands out of their mouth.

• Wash any toys or items that your child places in their mouth.
