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.
Pinworm eggs become infective within a few hours after being deposited on the skin around the anus and can survive for 2 to 3 weeks on clothing, bedding, or other objects.
Pinworm infections are very common, affecting approximately 1 billion people worldwide. 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.
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 eggs can also be transferred to the fingers from clothing or bedding, and then spread around the home. Eggs may be inhaled from the air or deposited onto food and swallowed. Pinworms can survive up to two weeks on clothing, bedding or other objects, if kept at room temperature.
Call your child's school or childcare center so that they can take extra steps to prevent the spread to others. Your child can return to school or childcare 24 hours after treatment.
The eggs, which are too small to see, will contaminate whatever they come in contact with: bedclothes, underwear, hands and food touched by contaminated hands. Even pinworm eggs floating in the air can be swallowed and cause infection. Pinworms are very contagious.
Washing your hands with soap and warm water after using the toilet, changing diapers, and before handling food is the most successful way to prevent pinworm infection.
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.
When you scratch the itchy area, the eggs cling to your fingers and get under your fingernails. The eggs then get transferred to other surfaces, such as toys, bedding or toilet seats. The eggs can also be transferred from contaminated fingers to food, liquids, clothes or other people.
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.
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.
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.
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.
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.
Prevention of Pinworm Infestation
Pinworm reinfestation is common because viable ova may be excreted for 1 week after therapy, and ova deposited in the environment before therapy can survive 3 weeks. Multiple infestations within the household are common, and treatment of the entire family may be necessary.
Pyrantel pamoate is in most over-the-counter (OTC) treatments for pinworms. This includes Reese's Pinworm Medicine and Pin-X. Prescription-strength medications are also available. Your doctor may prescribe a two-dose treatment of mebendazole or albendazole to help you clear the infection.
Children may return to child care if they are well enough to participate in activities and they have received their first treatment dose, have bathed and have trimmed and scrubbed their nails. All others may attend work, school and other activities provided good hygiene and hand-washing is practiced.
Call the doctor if your child complains of itchy skin or always seems to be scratching the anal or vaginal area. Also ask if pinworms could be why your child has trouble sleeping or has begun to wet the bed.
Pinworms do not cause abdominal pain, bloody bowel movements,fevers, or poor appetite. If the person has any of these signs or symptoms, they may have a more serious condition and should call a doctor or visit the hospital's emergency department.
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.
If you, your child, or someone in your household has symptoms of pinworm infection, call the doctor and ask about the tape test. Simply take a clear piece of tape and press the sticky side to the skin around the anus. Do this as soon as you or your child wakes up -- before you use the bathroom, shower, or get dressed.
Up to half of kids, typically between ages 5 to 10, will get a pinworm infection at some point, according to the Centers for Disease Control and Prevention. It is the most common parasitic infection in the U.S.
