An adult pinworm generally is 1/4 to 1/2 inch (about 6 to 13 millimeters) in length. The most common symptom of infection is
You might have anal itching, especially at night. You could also have stomach pain, nausea, or vaginal itching. Sometimes pinworms can be seen around your anus or on your underwear or bed sheets about 2 to 3 hours after you've gone to bed. Most of the time, pinworms don't cause major problems.
Itching during the night in a child's perianal area strongly suggests pinworm infection. Diagnosis is made by identifying the worm or its eggs. Worms can sometimes be seen on the skin near the anus or on underclothing, pajamas, or sheets about 2 to 3 hours after falling asleep.
The eggs are laid in a sticky, jelly-like substance that, along with the wriggling of the female pinworm, causes severe itching.
The worm may be seen around the anus or on the child's bottom. It is especially active at night or early morning. Rarely, the pinworm is seen on the surface of a stool. The pinworm's secretions are a strong skin irritant and cause the itching.
Summary. Pinworm is the most common worm infection in Australia. The major symptom is an itchy bottom, particularly at night. Treatment usually includes a single or 2-dose course of medication that should be taken by all members of the affected household.
Pinworm, or Enterobius vermicularis, is a small intestinal roundworm about the size of a staple. 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.
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.
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. The best way to diagnose this infection is to do a tape test.
The second option is to touch the perianal skin with transparent tape to collect possible pinworm eggs around the anus first thing in the morning. If a person is infected, the eggs on the tape will be visible under a microscope.

According to the CDC, pinworms can survive for up to 2 to 3 weeks in the home. So parents…you have a lot of cleaning to do to get rid of that itchy feeling you just got, and to ensure your family does not re-infect themselves. Where should you start when it comes to cleaning your home post-pinworm infection?
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.
Adults are rarely affected, except for parents of infected children. Infection often occurs in more than one family member. While an infected person sleeps, female pinworms crawl out of the anus and lay their eggs on the surrounding skin.
People are most likely to get pinworms if they swallow their eggs. This can happen if a person with pinworms scratches around the anus. Then the person gets eggs on his or her hands or under the fingernails. You can then get pinworms if you touch that person or if you touch something he or she touched.
If left untreated, the intense itching and scratching associated with these infections will result in secondary bacterial infections. Some of these may be difficult to treat. Untreated people can continue to infect other people.
Threadworms do not go away by themselves, and people do not build up immunity to them, so they must be treated in order to eradicate them totally from the body.
Kids in school get pinworms easily because they spend a lot of time with other kids, who may have pinworms. They might touch something with pinworm eggs on it when they're playing with other kids and eat the eggs without even knowing it.
To treat pinworm infection, your doctor may recommend over-the-counter pyrantel pamoate or prescribe medication to all members of your household to prevent infection and reinfection. The most common prescription anti-parasite medications for pinworms are: Mebendazole. Albendazole (Albenza)
The C. elegans sleep-like behavior is surprisingly similar to the sleep of humans and other mammals. In this state, the worm stops moving, relaxes, and uncurls its body. It also shows reduced neuronal activity and is less responsive to stimuli, but will then"wake up" if an experimenter pokes it too much.
See a GP if you:
find a large worm or large piece of worm in your poo. have a red, itchy worm-shaped rash on your skin. have sickness, diarrhoea or a stomach ache for longer than 2 weeks. are losing weight for no reason.
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.
You must do this straight away after getting up from bed. ❖ Change and wash underwear, nightwear (and bed linen if possible) each day. Avoid shaking clothes and linen as any eggs on them may be wafted into the air and be swallowed.
A person is infected with pinworms by ingesting pinworm eggs either directly or indirectly. These eggs are deposited around the anus by the worm and can be carried to common surfaces such as hands, toys, bedding, clothing, and toilet seats.
