Enterobiasis

A pinworm infection or enterobiasis is a human parasitic disease and one of the most common parasitic worm infections (also called helminthiasis) in the developed world. It is caused by infestation of the parasitic roundworm Enterobius vermicularis, commonly called the human pinworm. Infection usually occurs through the ingestion of pinworm eggs, either through contaminated hands, food, or less commonly, water. The chief symptom is itching in the anal area. The incubation time from ingestion of eggs to the first appearance of new eggs around the anus is 4 to 6 weeks.
