The female pinworms lay eggs in the folds of skin around the anus. The presence of these eggs often causes itching and irritation. When a person scratches the affected area, the pinworm eggs are transferred to the fingers. The eggs can survive for several hours on your hands.
Pinworm infection is caused by the helminth (Enterobius vermicularis), a small, white parasitic worm. The pinworm is about the length of a staple (ranges from 2 to 13 mm [0.08 to 0.5 inches]) and lives for the most part in the rectum of humans. While an infected person is asleep, female pinworms exit the intestines through the anus and deposit eggs on the skin around the anus.
