Overview
Pinworms are particularly common in children. The prevalence of pinworms is not associated with gender, race, social class, or culture. The pinworm has a worldwide distribution, and is the most common helminth (i.e., parasitic worm) infection in the United States and Western Europe.
Epidemiology and Demographics
Pinworm infections are more common within families with school-aged children, in primary caregivers of infected children, and in institutionalized children.
Age
The people most likely to be infected with pinworm are children under 18. In these groups, the prevalence can reach 50%. The prevalence in this age group has been reported to be as high as 61000 in India, 50000 in England, 39000 in Thailand, 37000 in Sweden, and 29000 in Denmark per 100,000 population. It is estimated that over 200 million people are infected annually. It is more common in the temperate regions of Western Europe and North America, (it being relatively rare in the tropics) and is found particularly in children. Samples of Caucasian children in the U.S.A. and Canada have shown incidences of infection of between 30% to 80%, with similar levels in Europe.
Gender
The prevalence of pinworms is not associated with gender.
Race
The prevalence of pinworms is not associated with any particular race, social class, or culture.
Developed Countries
The pinworm has a worldwide distribution and is the most common helminth (i.e., parasitic worm) infection in the United States and Western Europe. In the United States, a study by the Center for Disease Control reported an overall incidence of 11,400 per 100,000 people of all ages.
Habitat
The pinworm lives in the large intestine and cecum. It is found worldwide and causes the most common infection enterobiasis in humans. Unlike many other intestinal parasites, the pinworm does not usually enter the bloodstream or any other organs besides the intestines. Only in rare cases pinworms are found in the vagina, and even more rarely in the uterus, fallopian tubes, liver, and peritoneum, but the worms cannot survive long in these places.
