Pinworms are small, white worms (Enterobius vermicularis) that infest the intestines.
The worms, which look like quarter-inch-long pieces of dental floss, can be seen wiggling around the anus and in the stool.
It can be upsetting to discover that your baby has pinworms, but keep in mind that this common childhood malady isn't a sign of poor hygiene.
Also, the worms pose no health risks, and — unlike lice — are easily eradicated.
