What are pinworms?

  • Pinworms are small, white, threadlike worms that live in the large intestine and are usually 0.25” to 0.5” long.

Signs or Symptoms

  • Itching and irritation around the anal or vaginal area.
  • Pinworms are dangerous.
  • Are relatively common among preschool and school aged kids.
  • Are easily shared within these age groups.

Incubation and Contagious Period

  • Incubation period occurs 1 to 2 months or longer from the time of ingesting the pinworm egg until an adult worm migrates to the anal area.
  • Contagious period occurs as long as the female worms are discharging the eggs to the skin around the anus.

How are pinworms spread?

  • Through fecal-oral route.
  • Directly or indirectly by sharing of toys, bedding, clothing, toilet seats, or baths.
  • Pinworm eggs remain infective for 2 to 3 weeks in indoor environments.
  • Infestation with pinworms commonly clusters within families.

How is it controlled?

  • Practicing good hand hygiene is the most effective method of prevention.
  • Treatment with oral medications once or repeated in 2 weeks may be necessary for the whole family and the group of children who share a common environment.

Caregivers, Teachers, and Family Roles

  • Report the infection to staff members of the child care program or school facility for a decision making and action related care of the ill child.
  • Alert infection to all family members who might be exposed.
  • Suspect pinworm infection if a child has intense itching around the anal or vaginal area. The worms may be seen with a flashlight as 0.5” long crawling threads in the area of the anus after the child as been asleep for about an hour.
  • It’s important to see a health professional for recommended treatments.
  • Bathe the child in the morning to remove a large proportion of eggs that are laid at night.
  • Frequently change underwear, bedclothes, and bed sheets to decrease the amount of egg contamination.
  • Wash children’s hands directly after using the toilet and before putting something anything in their mouths, like food.
  • Frequently clean and sanitize toys and surfaces that are used for eating, toileting, hand washing, food preparation, and diapering.

Group Settings

  • It is unnecessary to exclude children from group settings.
