Pinworms, also known as Enterobius vermicularis, are small, white parasitic worms that live in the human intestinal tract, specifically the colon and rectum. They are a common intestinal parasite, especially in children, and can cause a variety of symptoms.

Symptoms of pinworm infection include:

Itching and irritation around the anus, which is usually worse at night. This is caused by the female pinworms laying their eggs in the skin around the anus.

Insomnia.

Abdominal pain

Loss of appetite

Nausea

Generalized fatigue

Irritability and restlessness

Difficulty in concentration

Anemia

Vaginal itching in girls

Rectal itching

Perianal itching

Irritation of the anus and vaginal area

Loss of appetite

Nausea

Generalized fatigue

Irritability and restlessness

Difficulty in concentration

Anemia

Diagnosis of Pinworm Infection

The diagnosis of pinworm infection is typically made by identifying the worms or their eggs during a physical examination of the anus and surrounding area. A doctor may also use a tape test, in which a piece of transparent tape is pressed against the anus and then examined under a microscope for the presence of eggs.

Treatment for Pinworm Infection

Pinworm infections can be treated with medications that are taken orally, such as mebendazole and albendazole. These drugs work by paralyzing the worms, which are then passed out of the body in the stool. It is important to note that these medications do not kill the eggs, so it is important to repeat the treatment in 2 weeks to kill any new worms that have hatched from eggs that were not killed in the first treatment.

In addition to medication, there are several things that can be done to help reduce the risk of reinfection and to alleviate symptoms:

Keep fingernails short and clean, to reduce the risk of scratching the anus and transferring eggs to the fingers.

Wash hands thoroughly, especially after using the toilet and before eating.

Keep the anus and surrounding area clean, by taking a shower or bath instead of a tub bath, and using a mild soap.

Wash all bedding, clothing, and underwear in hot water and dry on a hot setting, as eggs can survive on these items.

Avoid scratching the anus and surrounding area, as this can cause the eggs to be transferred to the fingers and then to other surfaces.

Pinworm infections are highly contagious and can easily spread to others through close contact or by touching contaminated surfaces. It is important to take steps to prevent the spread of infection to others, especially in households or other close-knit communities.

Preventing pinworm infections can be done by:

Washing hands regularly and thoroughly, especially after using the toilet and before eating

Keeping fingernails short and clean

Keeping the anus and surrounding area clean

Avoiding scratching the anus and surrounding area

Washing all bedding, clothing, and underwear in hot water and dry on a hot setting
