The worms are white and look like small pieces of thread. You may notice them around your child's bottom or in their poo. They don't always cause symptoms, but people often experience itchiness around their bottom or vagina. It can be worse at night and disturb sleep.
The most common symptom of infection is anal itching, particularly at night, as worms migrate to the host's anal area to lay their eggs. Pinworm infection is the most common type of intestinal worm infection in the United States and one of the most common worldwide.
A person with intestinal worms may not have any symptoms, but threadworms (Enterobius vermicularis), the most common worm infection in Australia, often do cause symptoms. A person with threadworms (also known as pinworms) may have an itchy bottom or redness and scratch marks around the bottom.
The female adult worms leave the anus in the middle of the night while the person is sleeping to deposit her eggs around the skin of the perianal region.
Other symptoms can include:
extreme itching around the anus or vagina, particularly at night. irritability and waking up during the night.
At night, the female adult worms deposit their eggs outside the rectum or anal area. One way to detect pinworms is to shine a flashlight on the anal area. The worms are tiny, white, and threadlike. If none are seen, check for 2 or 3 additional nights.
Pinworm infections often produce no symptoms but, when they occur, symptoms can include: itchy bottom, especially at night.
Causes of itchy bottom
a bacterial infection – such as those that cause streptococcal infections. a skin condition – such as atopic eczema, where the skin becomes red, dry and flaky. haemorrhoids (piles) – swellings that contain enlarged and swollen blood vessels in and around the anus.
Pinworms can survive up to two weeks on clothing, bedding or other objects, if kept at room temperature.
Pinworm eggs can be collected and examined using the “tape test” as soon as the person wakes up. This “test” is done by firmly pressing the adhesive side of clear, transparent cellophane tape to the skin around the anus. The eggs stick to the tape and the tape can be placed on a slide and looked at under a microscope.
small, white worms in your poo that look like pieces of thread. extreme itching around your anus, particularly at night.
The life cycle of threadworms
This tends to occur at night when you are warm and still in bed. The eggs are too small to see without a microscope, but cause itching around the anus due to accompanying irritating mucus. You then scratch around the anus to relieve the itching.
It moves. If it doesn't wiggle, it's probably lint or a thread. The worm may be seen around the anus or on the child's bottom. It is especially active at night or early morning.
Formication is a symptom where you hallucinate the feeling of insects crawling in, on or underneath your skin. This symptom has many possible causes, including mental health disorders, medical conditions and more. This symptom is often treatable, with available treatments depending on the cause and other factors.
Wash bedsheets, pajamas, underwear, washcloths and towels in hot water to help kill pinworm eggs. Dry on high heat.
Wash hands and scrub nails each morning. Always wash hands before meals or snacks, before preparing food, and after going to the toilet or changing nappies. ❖ Every morning have a bath, or wash around the anus, to get rid of any eggs laid overnight. You must do this straight away after getting up from bed.
The medications used for the treatment of pinworm are either mebendazole, pyrantel pamoate, or albendazole. Any of these drugs are given in one dose initially, and then another single dose of the same drug two weeks later. Pyrantel pamoate is available without prescription.
An itchy bottom that's worse at night is often caused by threadworms, especially in children. Children under 2, and pregnant and breastfeeding women, cannot usually take medicine for threadworms – see a GP, midwife or health visitor instead.
In the evening, the body releases more heat, and blood flow to the skin increases, which may contribute to nighttime itching. In addition, skin loses water at night, resulting in dryness that can make you itchy.
Itchy skin at night, also known as nocturnal pruritus, happens when you have the urge to itch and scratch your skin in the middle of the night. This can disturb your sleep. Itchy skin at night can happen because of changes to your body temperature, dry skin or as a symptom of an underlying condition.
Although not all infected people will have symptoms, many will experience itching around the rectum. Some females may also experience itching in the genital area. How soon do symptoms appear? Symptoms usually are noticed one to two months after infection.
Your child may be fussy and wake often at night. If your child is infected, it may take 2 to 8 weeks for symptoms to start.
How long does pinworms last? The life cycle of a pinworm is 4 to 6 weeks. Without treatment, infestation will continue as long as fresh eggs are being swallowed, unless a person develops immunity to pinworms, which is unusual before age 15.
