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.
Spread among family members is common. Animals do not harbor pinworms - humans are the only natural host for this parasite. The most common symptom of pinworms is an itchy rectal area. Symptoms are worse at night when the female worms are most active and crawl out of the anus to deposit their eggs. Although pinworm infections can be annoying, they rarely cause serious health problems and are usually not dangerous.
