The eggs pass into the digestive system, where they hatch. About 1 to 2 months later, adult female pinworms lay eggs on the skin right around the anus, which makes the area itchy. Often, this happens at night.
The best way to diagnose this infection is to do a tape test. The best time to do this is in the morning before bathing, because pinworms lay their eggs at night.
Pinworms are tiny, white, thread-like worms that live in the rectum. The worms crawl out of the anus (bum) at night and lay their eggs on nearby skin.
Symptoms of a pinworm infection (enterobiasis) include: Anal itching, especially at night: Pinworms lay their eggs around the anus at night, causing itching and irritation. While symptoms are usually mild, anal itching can be severe.
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 eggs pass into the digestive system, where they hatch. About 1 to 2 months later, adult female pinworms lay eggs on the skin right around the anus, which makes the area itchy. Often, this happens at night.
What to Expect: After taking the pinworm medicine, itching should stop in 5 to 7 days.
How is pinworm infection diagnosed? 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.
How long after exposure do symptoms begin? Two to six weeks.
In order to stop the spread of pinworm and possible re-infection, people who are infected should shower every morning to help remove a large amount of the eggs on the skin. Showering is a better method than taking a bath, because showering avoids potentially contaminating the bath water with pinworm eggs.
After a few weeks, the female pinworms move to the end of the large intestine, and they come out of the body at night to lay their eggs around the anus (where poop comes out).
Do not scratch. Itching around the anus caused by a pinworm infection usually happens at night. Try wearing gloves, pyjamas, and close-fitting clothing to help prevent scratching.
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.
The medicine usually takes approximately 72 hours to fully rid the system of pinworms. For several days after treatment, clean the bedroom floor by vacuuming or damp mopping. After treatment, wash bed linens and night clothes (don't shake them).
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.
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.
The test involves pressing the adhesive side of a piece of transparent tape to the skin around the anus of the person you suspect has pinworms as soon as the person awakens. The eggs stick to the tape. You then take the tape to your appointment so the doctor can look for pinworms or eggs under a microscope.
For the itching, wash the skin around the anus with warm water. For severe itch, use 1% hydrocortisone cream (such as Cortaid) 2 times per day. Use for 1 or 2 days. No prescription is needed.
An itchy bottom in children is often caused by worms. If treatment for worms is recommended, other family members with the same symptom should also be treated.
How threadworms spread. Threadworms spread when their eggs are swallowed. They lay eggs around your bottom (anus), which make it itchy.
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.
Complete die-off within the tested exposure time range was noted for 70 °C, 75 °C and 80 °C, however treatment at 60 °C and 65 °C allowed for development of a few eggs after incubation.
Pinworm infection is very contagious. If you don't take precautions, it's easy to become reinfected. If anyone in your home has pinworms, take these steps to get rid of the pinworm eggs. Doing so will minimize your chances of reinfection.
Pinworms can usually be treated completely with two doses of over-the-counter medicine called pyrantel pamoate, available in the United States under the brand names Pin-X and Reese's Pinworm Medicine. Take one dose immediately and another dose two weeks later.
