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.
If pinworm infection occurs again, the infected person should be retreated with the same two-dose treatment. The infected person's household contacts and caretakers also should be treated. If pinworm infection continues to occur, the source of the infection should be sought and treated.
Causes of threadworms
Scratching the anus or vagina, or wiping them after going to the toilet, can cause the eggs to stick to your fingertips or under your fingernails. If you don't wash your hands, the eggs can be transferred to your mouth or on to food or objects, such as toys and kitchen utensils.
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.
Strict hygiene measures can clear up pinworm infection without medication, and reduce the risk of reinfection. The worm has a lifespan of about six weeks, therefore the strict hygiene needs to last that long.
Chlorine dioxide gas inactivates pinworm eggs in a non-invasive and non-corrosive manner.
The key is to break the 6-week cycle of pinworm reinfection by killing any live pinworms and preventing the ingestion of eggs. A diagnosis should be confirmed before treating with medications. Medications kill only the adult worms and have no effect on developing eggs and larvae.
Eggs can pass to other people when they touch these surfaces and then touch their mouth. They take around 2 weeks to hatch. Children can get threadworms again after they've been treated for them if they get the eggs in their mouth. This is why it's important to encourage children to wash their hands regularly.
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.
Complications. Typical pinworm infections don't cause serious problems. In rare circumstances, heavy infestations can cause infection of female genitals. The parasite can travel from the anal area up the vagina to the uterus, fallopian tubes and around the pelvic organs.
The people most likely to be infected with pinworm are children under 18, people who take care of infected children and people who are institutionalized. In these groups, the prevalence can reach 50%. Pinworm is the most common worm infection in the United States.

Worms are mainly spread in small bits of poo from people with a worm infection. Some are caught from food. You can get infected by: touching objects or surfaces with worm eggs on them – if someone with worms does not wash their hands.
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.
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.
