Threadworms in Humans – Pictures, Symptoms & Treatment
Threadworms are also recognized as pinworms and seatworms. Threadworm belongs to the class of parasites called the helminthes. Thread worms are tiny worms around 1 cm in length and look like white cotton threads. Once the egg is consumed or inhaled, it travels to the small intestine and quickly develops into adult worms. At night the female threadworm moves to the outer anal area and lays their eggs on the skin around the anus. One adult can produce around 10,000 eggs at one time. The eggs are picked up on fingers can be transferred back to the mouth and ingested again. Eggs on the fingers can be spread to other members of the family or to close friends. They can also drop off and become part of general household dust.

The existence of threadworms in the person can be diagnosed from stool exams and the presence itself of the worms in the anus through rectal physical assessment. Threadworm infection is expected among immigrants, returning travelers or military personnel, people who live in parts of Appalachia and the southeastern states and persons in homes for the retarded and similar institutions. In untreated patients, the disease has a high rate of reinfection caused by worms already presents in the body. This type of disease recurrence is known as autoinfection. Threadworms can remain inside humans for as long as 45 years after the initial infestation because of autoinfection.

Treatment of Threadworms in Humans

There are two methods to treat threadworms in humans, medications and Hygiene method.


  • Mebendazole: Mebendazole is the usual treatment for children aged over two years. It can be bought over-the-counter and is accessible as a chewable tablet or in liquid form. It prevents the threadworms to absorb glucose, which means that they will die within a few days. Second dose of mebendazole may be prescribed to be taken after two weeks. Mebendazole can cause abdominal pain or diarrhoea, particularly if the infection of threadworms is very severe.
  • Piperazine: Piperazine is an alternative medicine used to treat children who are between three months to two years of age. Piperazine paralyses the threadworms until they are pushed naturally out of the bowel. It is mixed with a medication called senna, which has a laxative effect to drive out the worms earlier. Piperazine and senna both come in a sachet of powder, which can be mixed with a small amount of milk or water before drinking. Second dose may be taken after two weeks. Piperazine is not suggested if the person have epilepsy or problem with liver or kidneys.

Hygiene method:

  • Clean the bathroom and kitchen carefully by ‘damp-dusting’ surfaces and washing the cloth regularly in hot water.
  • Avoid shaking any material that may have eggs on it like clothing or bed sheets, as this may transfer the eggs to other surfaces.
  • Vacuum and dust the whole house thoroughly paying particular attention to the bedrooms.
  • Keep your finger nails short.
  • Wash your hands frequently, and scrub under your finger nails, particularly before eating, after visiting the toilet, and before and after changing a nappy.
  • Discourage nail biting and finger sucking and make sure that children do not suck their thumb.
  • Wear close-fitting underwear at night and change your underwear every morning.
  • Wearing cotton gloves at night may help to prevent scratching while you are asleep.
  • Bath or shower regularly, particularly first thing in the morning and make sure that you clean around your anus and vagina to remove any eggs.
  • Ensure that everyone in your household has their own face flannel and towel. Avoid using communal towels.
  • Keep toothbrushes in a closed cupboard and rinse them thoroughly before use.
  • Do not eat food in the bedroom because you may end up swallowing eggs that have been shaken off the bedclothes.
  • Herbal Remedies for Threadworms:
  • Crush 15 to 25 tablespoons of fresh squash seeds and mix with sugar, milk, or water. You can drink this even when on an empty stomach.
  • Make a decoction from the leaves of a bitter gourd. Take half a cup of the decoction first thing in the morning before eating.
  • Eating high fiber soluble foods would help clean and sweep the intestinal linings. A fruit diet for 3 days would be very healthy and at the same time provide a cleansing and detoxification process.


  • Trim down your child’s fingernails to prevent accumulation of dirt.
  • Change underwear, night clothes, and sheets after each treatment. Because the eggs are sensitive to sunlight, open blinds or curtains in bedrooms during the day.
  • Get your child treated with purgative measures that is usually indicated and prescribed during the ages of 2 to 4 years old.
  • Eat healthy and nutritious foods regularly.
