The ‘sticky tape’ test involves sticking a piece of clear adhesive tape to the crease of the anus, and is best carried out at night. The adult worms can be seen with the naked eye, as thin, white, wriggling threads: look at the anus at night or at the surface of bowel motions.

Secondary bacterial infection of the perianal skin.Urinary tract infection particularly in children.However 40% of infested individuals have minimal symptoms or are asymptomatic What are the complications of pinworm infestation? Severe infestations rarely result in abdominal pain, nausea, or vomiting. This may result in an itchy vaginitis with a mucous or blood-stained discharge. The adult worms sometimes migrate to the vagina instead of returning to the bowel. The itchiness tends to be worse at night when the female worms are active on the skin surface and can cause trouble sleeping. The most common symptom caused by pinworms is itching around the anus. What are the clinical features of pinworm infestation? Pinworm infestation can spread during sexual intercourse. Others can come in contact with pinworm eggs and ingest them unknowingly, although the eggs survive only a few days in the environment. Infested individuals ingest the eggs (auto-infection) when biting their nails, or putting fingers in their mouth. When someone with pinworm scratches their perianal skin, the eggs are lodged beneath their fingernails, and can be deposited on clothing, toys, and furniture. The main way that pinworms spread is through swallowing the eggs. They can survive for up to 2 weeks on the skin. After exposure to the air, the microscopic eggs mature and are typically infectious within a few hours. The eggs are attached to the skin with an adhesive mix. It is thought to be the movement of the female worms that causes the itch. Why are pinworms so itchy at night?Īt night, the female adult pinworm emerges from the anus to deposit eggs onto the skin around the anus. The translucent eggs are an asymmetrical elongated oval shape visible under a microscope. They are visible to the naked eye - the female pinworm is 9-12 mm in length while the male is much shorter, 3-5 mm. They have a long thread-like appearance, are a white-beige colour, and round in shape (roundworm). It can affect all social classes, races, and countries. The worldwide infestation rate is estimated to be 1 billion. Family members are at particular risk of acquiring pinworms. Infestation or infection with pinworms is most common amongst school-aged children, in some communities affecting up to two-thirds of children aged 5-10 years. Pinworms ( Enterobius vermicularis) are also called threadworms or seatworms, and the condition they cause is called enterobiasis or, the older term, oxyuriasis.
