Pinworms are the most common worm infection in the United States. They are most common in school-age children. Pinworm eggs are spread directly from person to person. They can also be spread by touching bedding, food, or other items that are contaminated with the eggs. Typically, children are infected by touching pinworm eggs without knowing it and then putting their fingers in their mouth. They swallow the eggs, which eventually hatch in the small intestine. The worms mature in the colon. Female worms then move to the child's anal area, especially at night, and deposit more eggs.
