Pinworm infection (threadworm infection in the UK), also known as enterobiasis, is a human parasitic disease caused by the pinworm, Enterobius vermicularis. [3] The most common symptom is pruritus ani, or itching in the anal area. [1] The period of time from swallowing eggs to the appearance of new eggs around the anus is 4 to 8 weeks. [2]
Pinworm is the most common worm infection in the U.S., and up to half of kids can become infected at some time, according to the Centers for Disease Control and Prevention. We are the only hosts ...
In the United States, a study by the Center of Disease Control reported an overall incidence rate of 11.4% among children. [21] 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.

The lifetime of adult worms varies tremendously from one species to another but is generally in the range of 1 to 8 years (see following table). This lifetime of several years is a result of their ability to manipulate the immune response of their hosts by secreting immunomodulatory products. [4]
Strongyloides stercoralis is a human pathogenic parasitic roundworm causing the disease strongyloidiasis.Its common name in the US is threadworm.In the UK and Australia, however, the term threadworm can also refer to nematodes of the genus Enterobius, otherwise known as pinworms.
Spastic (tetanic) paralyzing agents, in particular pyrantel pamoate, may induce complete intestinal obstruction in a heavy worm load. [8] This obstruction is usually in the form of a worm impaction and happens when a very small, but heavily parasitized animal is treated and tries to pass a large number of dislodged worms at once.
A study of 459 children in Zanzibar revealed spontaneous increases in appetite after deworming. [25] Anorexia might be a result of the body's immune response and the stress of combating infection. [23] Specifically, some of the cytokines released in the immune response to worm infestation have been linked to anorexia in animals. [21]
Albendazole is a broad-spectrum antihelmintic and antiprotozoal agent of the benzimidazole type. [3] It is used for the treatment of a variety of intestinal parasite infections, including ascariasis, pinworm infection, hookworm infection, trichuriasis, strongyloidiasis, taeniasis, clonorchiasis, opisthorchiasis, cutaneous larva migrans, giardiasis, and gnathostomiasis, among other diseases.
