Pinworm (parasite)

Pinworm (parasite)

The Pinworm (Enterobius vermicularis), also known as threadworm or seatworm, is a parasitic worm. It is a nematode (roundworm) and a common intestinal parasite or helminth, particularly in humans.

Life Cycle

The life cycle of the pinworm begins with the ingestion of pinworm eggs. Once inside the body, the eggs hatch and mature within a few weeks. Adult pinworms live in the colon (large intestine) where they mate. Female pinworms move to the anal area to lay their eggs, which often results in anal itching. When the host scratches the anal area, microscopic pinworm eggs are transferred to the host's fingers. The eggs can then be spread to others or re-ingested by the host.

Symptoms

The most common symptom of a pinworm infection is anal itching, particularly at night. Other symptoms can include restlessness, insomnia, and abdominal pain. In severe cases, pinworms can cause weight loss and stunted growth in children.

Treatment

Treatment for pinworm infections involves medication to kill the parasites. The most commonly used medications are mebendazole, pyrantel pamoate, and albendazole. In addition to medication, it is important to maintain good personal hygiene to prevent re-infection.

Prevention

Prevention of pinworm infections involves maintaining good personal hygiene. This includes washing hands regularly, particularly before eating and after using the toilet, keeping fingernails short and clean, and avoiding scratching the anal area.
