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.
Scratching an affected area and then eating can lead to unintentionally ingesting pinworm eggs. This can lead to a repeat pinworm infection. Sometimes eggs on the anus hatch, and the larvae can reenter the large intestine. If not treated, this can cause the infection to continue indefinitely.
Medication can effectively treat pinworm infections, though reinfection is possible. Serious complications and long-term health effects are rare.
Reinfection occurs easily. Prevention always should be discussed at the time of treatment. Good hand hygiene is the most effective means of prevention. If pinworm infection occurs again, the infected person should be retreated with the same two-dose treatment.
Pinworm infection is very common, occurring in children much more often than in adults. As many as one in five children will be bothered by this parasite. Between 30 and 40 million people in the United States get this infection, many without even knowing it.
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.
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.
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)
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.
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.
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.
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.
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.
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.
For most people, treatment will involve taking a single dose of a medication called mebendazole to kill the worms. If necessary, another dose can be taken after 2 weeks. During treatment and for a few weeks afterwards, it's also important to follow strict hygiene measures to avoid spreading the threadworm eggs.
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.
The worms get into the body when people swallow the tiny pinworm eggs. The eggs can be on contaminated hands, under fingernails, and on things people touch a lot, such as: clothing, bed linens, and towels.
Pinworm is the most common worm infection in the United States. Experts estimate that one in ten people throughout the world become infected with pinworms.
Pinworm Infection Symptoms
Anal itching, especially at night. Restless sleep. Itching in the vaginal area -- if adult worms move to your vagina. Feeling irritable.
Life cycle of a pinworm

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.
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.
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.
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.
Coconut oil
It is a popular home remedy for pinworms, as many people believe that applying the oil around the anal area can prevent the female from laying eggs there. Some people also ingest a teaspoon of pure coconut oil each morning.
