Overview
The pinworm has a worldwide distribution,[1] and is the most common helminth (i.e., parasitic worm) infection in the United States and Western Europe.[2] In the United States, a study by the Center of Disease Control reported an overall incidence rate of 11.4% among people of all ages.[2] Pinworms are particularly common in children, with prevalence rates in this age group having been reported as high as 61% in India, 50% in England, 39% in Thailand, 37% in Sweden, and 29% in Denmark.[2] Finger sucking has been shown to increase both incidence and relapse rates,[2] and nail biting has been similarly associated.[3] Because it spreads from host to host through contamination, pinworms are common among people living in close contact, and tends to occur in all people within a household.[1] The prevalence of pinworms is not associated with gender,[1] nor with any particular social class, race, or culture.[2] Pinworms are an exception to the tenet that intestinal parasites are uncommon in affluent communities.[2] The earliest known instance of pinworms is evidenced by pinworm eggs found in coprolite, carbon dated to 7837 BC at western Utah.
