Enterobius vermicularis

Enterobius vermicularis, also known as the pinworm or threadworm, is a type of parasite that lives in the human gastrointestinal tract. It is the most common parasitic worm infection in the United States and Western Europe.

Life Cycle[edit | edit source]

The life cycle of Enterobius vermicularis begins when eggs are ingested, usually due to poor hygiene or from contaminated surfaces. The eggs hatch in the small intestine and mature into adults in the colon. Female worms migrate to the anus to lay their eggs, causing intense itching.

Symptoms[edit | edit source]

The most common symptom of an Enterobius vermicularis infection is anal itching, especially at night. Other symptoms can include restlessness, insomnia, and abdominal pain. In rare cases, the worms can migrate to other parts of the body, causing serious complications.

Diagnosis[edit | edit source]

Diagnosis of Enterobius vermicularis is usually made by the "tape test", where a piece of clear tape is applied to the anal area in the morning before bathing. The tape is then examined under a microscope for the presence of eggs.

Treatment[edit | edit source]

Treatment for Enterobius vermicularis typically involves a two-dose regimen of medication, such as mebendazole or albendazole. All members of the household may need to be treated to prevent reinfection.

Prevention[edit | edit source]

Prevention of Enterobius vermicularis involves good hygiene practices, such as regular hand washing, cleaning under fingernails, and washing bedding and clothing regularly.
