A person can have anywhere from a few to hundreds of pinworms, with each female laying thousands of eggs (around 10,000-16,000), causing intense itching as they deposit them at night around the anus. Pinworm infections are very common, especially in children, and spread easily through swallowed eggs from contaminated surfaces or hands, making it possible for whole families to get infected.
Children or families can have pinworm infections several times. If your child's symptoms return after treatment, go back to their pediatrician. If you or another family member has symptoms, see a healthcare provider.
This is an easily transmissible infection that is very common in families with small children. 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.
Most often, swallowing pinworm eggs causes a pinworm infection. The eggs spread through stool. This can be carried to the mouth by tainted food or drink or by unwashed fingers. Once swallowed, the eggs hatch in the small intestine.
Risk factors for pinworms include poor hygiene, eating after touching contaminated items and living with an individual who is identified as egg positive.

By an infected child not washing hands after using the bathroom. If the child then touches playmates or toys, he/she may pass on the eggs. 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.
Life cycle of a pinworm
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.
Pinworm eggs are infective within a few hours after being deposited on the skin. They can survive up to two (2) weeks on clothing, bedding, or other objects. The pinworms grow to adult size within two (2) to six (6) weeks. Pinworm infections can be spread as long as either worms or eggs are present.
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. bathroom surfaces.
Other types of worms may not cause any symptoms for example pork and beef tapeworms or strongyloides stercoralis. Other types of worms, such as dog tapeworm, may only cause symptoms after a long time, or if there is a severe infection.

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.

How do you get pinworms? Pinworm eggs are spread from direct transfer between hands and anus to the same person or others. Indirectly they can spread through clothing, bedding, food and other articles in the living environment. Dust may spread the eggs in heavily contaminated households and indoor environments.
