Facts
Pinworms are the most common intestinal nematode and there are an estimated 30,000 cases per year in the United States.
Infestation cans occur world wide but are more common in temperate climates. The prevalence of an infection is lowest during infancy and is highest in school age children (ages 5-14). Infections can affect multiple family members. Pinworm are also known as "threadworms" and affect only humans. |
Description
|
Pinworms are threadlike, white worms which are approximately 1 cm long (the size of a standard staple). Pinworm infestations affect the small and large intestines but are nothing to be afraid of! They often can be visualized 2-3 hours after a child falls asleep at night near the anus.

Transmission
|
Pinworm eggs are often ingested from soil, water contamination, or direct fecal-oral contact. This can occur from contact with contaminated bedding, clothing, toys, baths, and also may be transmitted from person to person. They can also be transmitted through air or dust and inhaled. In addition, an egg can remain viable for 20 days in a moist environment. After the egg is inside the body it travels to the intestines where it later hatches. The worm then thrives and begins to grow and travel inside the small intestine, making its way to the large intestine. Female eggs then lay their eggs near the opening of the anus. This process usually occurs 1-2 months after ingestion of the egg.

Healthy People 2020 recognize the need to improve health measures to promote well-being in early and middle childhood. Goals that support well-being in this population include self discipline and the ability to make good decisions. Both of these goals can impact the risk a child is at for transmissible diseases including pinworms. By fostering knowledge and providing education to parents, caregivers, and the child themselves positive outcomes will occur.
