Pinworms are contagious and easily spread, usually from child to child. Pinworm eggs can be picked up on children's fingers when they're playing. When children who are infected scratch their itchy bottoms, the tiny eggs can get under their fingernails.
How is pinworm infection spread? Pinworm infection is spread by the fecal-oral route, that is by the transfer of infective pinworm eggs from the anus to someone's mouth, either directly by hand or indirectly through contaminated clothing, bedding, food, or other articles.
Pinworms spread easily. When people who are infected touch their anus, the eggs attach to their fingertips. They can spread the eggs to others directly through their hands, or through contaminated clothing, bedding, food, or other articles. The eggs can live on household surfaces for up to 2 weeks.
When and for how long is a person able to spread the disease? A person will remain infectious for as long as there are worms laying eggs on the skin around his or her rectum. Pinworm eggs can remain infectious in an indoor environment for two to three weeks.
Pinworm infections are highly contagious. The infection cycle typically follows these steps: An individual acquires an infection by ingesting or inhaling pinworm eggs. These microscopic eggs are usually deposited onto a surface by a person with the infection.
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.
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.
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.
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.
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.
Use clean washcloths or paper towels each time. Scrub the toilet seat daily with disinfectant or soap and water (Picture 2). Wipe down any toys that your child usually puts in his mouth or hard surfaces that he has touched with disinfectant or soap and water.
Pinworm eggs become infective within a few hours after being deposited on the skin around the anus and can survive on objects for 2 to 3 weeks.
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.
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.
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.
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.
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.
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.
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.
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.
If a person with a pinworm infection touches their underwear, bedsheets, or their anus, they can pick up eggs on their fingers. If they touch another surface, they can leave the eggs there. Anyone who touches that surface and then touches their mouth is at risk of infection.
If your child develops a pinworm infection, try not to worry. Pinworms don't cause any harm (just itching and restless sleep), and it won't take long to get rid of them.
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.
Pinworm eggs can cling to surfaces, including toys, faucets, bedding and toilet seats, for two weeks. So besides regular cleaning of surfaces, methods to help prevent the spread of pinworm eggs or to prevent reinfection include: Wash in the morning.
