Thread Worm

Subject: Community Health Nursing II

Overview

Threadworm is an intestinal nematode found in the caecum and vermiform appendix of humans. Threadworm is sometimes known as pinworm or seatworm. The large intestine is the primary habitat of threadworm. Threadworms have three morphological forms: eggs, larvae, and adults. Its life cycle is completed in a single host. Its clinical symptoms include pruitis and dermatitis around the anus and perineum, as well as nocturnal enuresis. Finding adult worms and displaying the eggs can help to diagnose it. It can be treated with the right medications at the right time, such as mebendazole, pipetaxine citrate, albendazole, and pyrantel pamoate. It can be avoided by practicing basic personal hygiene, such as hand washing with clean water and soap, frequent washing of linen, and timely treatment of wounds. It can be avoided by practicing proper personal hygiene, such as hand washing with clean water and soap, frequent laundry, and prompt treatment of the infected person.

It is a nematode that lives in the human caecum and vermiform appendix. It has a global range but is more frequent in cold and temperate settings. It is also known as threadworm, pinworm, and seat worm.

Habitat

It lives inside the large intestine.

Morphology

 It has the following morphological forms, they are:

  • Eggs
  • Larva
  • Adults

Life cycle

This worm's life cycle is completed in a single host. Infection occurs when eggs containing larvae are consumed. These eggs are laid on the perianal skin, and finger contamination with these eggs occurs during scratching.

Because the egg shells are dissolved by digestive acids, the larvae escape and mature into worms in the small intestine. The male worm dies after fertilizing the female. The pregnant woman then moves down the colon to the rectum.

The fertilized female then descends and emerges from the anus at night to deposit eggs on the perianal skin. These eggs are then swallowed by contamination of fingers while scratching, and the cycle begins again. As a result, no intermediate host is required.

Clinical Features

  1. Pruitis and an eczematous condition around the anus and perineum.
  2. Nocturnal enuresis.

Laboratory Diagnosis

  • Finding of adult worms

    • Worms are frequently detected by the patient or the child's parents. The characteristics of these worms identify them as Enterobius vermicularis.

  • Demonstration of eggs
    • Eggs are typically demonstrated by an NIH (National Institute of Health) swab scraped from the perianal area. The swab should be taken as soon as the patient awakens in the morning.

Treatment

  • Pyrantelpamoate
  • Mebendazole
  • Albendazole
  • Pipetaxine citrate
  • Prophylaxis

Prevention

  • Handwashing, finger nail cleaning, and regular bathing are examples of personal hygiene.
  • Washing nightwear and bed linen on a regular basis.
  • Treatment of infected individuals
