Symptoms of pinworm infection may include: Itching of the anal or vaginal area. Insomnia, irritability, teeth grinding and restlessness. Occasional stomach pain and nausea.
Pinworm infection (called enterobiasis or oxyuriasis) causes itching around the anus which can lead to difficulty sleeping and restlessness. Symptoms are caused by the female pinworm laying her eggs. Symptoms of pinworm infection usually are mild and some infected people have no symptoms.
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.
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.
Most people don't experience serious complications from pinworm infections, but in rare cases the following complications can occur: Urinary tract infections (UTIs). UTIs can develop if you do not treat the pinworm infection. Vaginitis and endometritis.
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.
Finding the female worm or the eggs confirms the diagnosis of pinworms. To find a female worm: At night, the adult worms can sometimes be seen directly around the anal area or in pajamas. The worm (one-quarter to one-half inch long) is clearly visible to the naked eye.
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.
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.
Medication can effectively treat pinworm infections, though reinfection is possible. Serious complications and long-term health effects are rare.
Pinworms are also called “threadworms.” They're the most common type of intestinal worm infection in the U.S., and one of the most common in the world. They're thin and white, and about one-quarter to one-half inch long -- about as long as a staple. Tapeworms are flatworms that look a bit like ribbons.
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.
Most pinworm infections are mild and easily treated. Your doctor may prescribe a single chewable tablet of a medicine called mebendazole. A second tablet is taken about 3 weeks later if the infection isn't cured. Or your doctor may recommend another kind of medicine called pyrantel, which is taken as a single dose.
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.
People of all ages can become infected with pinworms, but the infections are found most often in children. Caregivers and family members of infected children have a higher risk of infection.
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 infestation is very rarely fatal; death and morbidity are from secondary infection. A 28% to 68% increased risk for appendicitis is associated with pinworm infestation.
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.
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). The amount of time that passes from when someone swallows the eggs until the worms lay new eggs is about 1 to 2 months.
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. The eggs become infectious within a couple of hours after being deposited and can survive for about 2 weeks outside the host.
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.
Anyone can get a pinworm infection. It's the most common kind of worm infection in the United States. But it's more likely if: You're between the ages of 5-10.
Life cycle of a pinworm
A grown pinworm is yellowish white, slender and about one centimetre long. Around 4 weeks after ingestion, the adult female moves down the gut and exits the body via the anus to lay a batch of eggs on the surrounding skin, often at night. The worm then dies, her reproductive mission complete.
Anal itching (pruritus ani) is a skin condition that affects your perianal area, which may become worse at night or after a bowel movement.
