are pinworms visible
Young children and their household members, including adults, are at risk for pinworm infections. Pinworms are visible. They range in size from 2-13 mm, are white, and resemble a worm but the pinworm eggs are small, transparent and can be seen only with a microscope. Pinworm infections are spread person-to-person by ingesting pinworm eggs that have contaminated fingers, bedding, clothing or other items.
