Pinworms can survive up to two weeks on clothing, bedding or other objects, if kept at room temperature.
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.
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.
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.
Encourage children to avoid scratching their bare anal areas. Pinworm eggs continue to be present (excreted) in the feces of an infected person for up to a week after the treatment, so precautions should be taken to prevent reinfection by washing hands thoroughly, especially under the nails.
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.
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)
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 you have pinworms, you might see the worms in the toilet after you go to the bathroom. They look like tiny pieces of white thread. You also might see them on your underwear when you wake up in the morning. But the pinworm eggs are too tiny to be seen without a microscope.
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.
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.
Eggs can live for 2 to 3 weeks outside the body. They can be found in house dust, on toilet seats, bed linens and toys and in play areas in or outside the home. Although pinworms only grow in humans, the eggs can be carried in a pet's fur.
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.
If you are self-treating for pinworms, take the medication once only. Do not repeat the dose without talking with your doctor first. Depending on the type of worm infection you have, your doctor may direct you to take the medication only once or for several days.
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.
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.
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 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.
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.
The worms die after about six weeks. Provided that you do not swallow any new eggs, no new worms will grow to replace them. So, if you continue the hygiene measures described above for six weeks, this should break the cycle of re-infection, and clear your gut of threadworms.
Reinfection does happen with pinworm
Eggs are swallowed, usually after hand-to-mouth contact, and the pinworm infection begins again. Pinworm eggs may spread to shared surfaces, such as bedding, curtains, toilets, doorknobs, towels, utensils, and furniture. These areas should be kept clean to avoid reinfection.
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.
