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.
By Mayo Clinic Staff. Accidentally swallowing or breathing in pinworm eggs causes a pinworm infection. The microscopic eggs can be carried to your mouth by contaminated food, drink or your fingers. Once swallowed, the eggs hatch in the intestines and mature into adult worms within a few weeks. Female pinworms move to the anal area to lay their eggs, which often results in anal itching. When you scratch the itchy area, the eggs cling to your fingers and get under your fingernails.
