Pinworm

According to the Center for Disease Control, Pinworm is the most common worm infection in the U.S. School-age children; followed by pre-schoolers, have the highest rates of infection.

A pinworm infection is caused by a small, white intestinal worm called Enterobius vermicularis. Pinworms are about the length of a staple and live in the rectum of humans. While an infected person sleeps, female pinworms leave the intestines through the anus and deposit egos on the surrounding skin.

Itching around the anus, disturbed sleep, and irritability are common symptoms. Eggs are infective within a few hours after being deposited on the skin. They can survive up to two weeks on clothing, bedding, or other objects. Children can become infected by accidentally swallowing infective pinworm eggs from contaminated surfaces or fingers.

If you suspect pinworms, consult your physician who will instruct you regarding sample gathering for microscopic examination. Both over-the-counter and prescription treatments are effective. Treatment involves a two-dose course. The second dose is normally given two weeks after the first.

To prevent the spread of infection:

  • Bathe immediately upon awakening to reduce egg contamination
  • Change nightclothes frequently
  • Change underwear, pj's and sheets after each treatment
  • Pinworm eggs are susceptible to sunlight, so open blinds and curtains in bedrooms during the day.
  • Wash hands after going to the toilet, before eating, and after changing diapers
  • Trim fingernails short
  • Discourage nail biting and scratching bare anal areas to reduce self-reinfection.
