What is pinworm infection?
Pinworm infection is an infection of the large intestine and anal area by a small, white parasite that resembles a "worm." The medical name for the parasite is Enterobius vermicularis, but it is commonly termed a pinworm in both the lay and medical literature. These parasites are also termed seatworms or threadworms, and the infections is medically termed enterobiasis or helminthiasis. Pinworms and other parasitic worms (as a group are termed helminths) feed off of the host animal by adsorbing nutrients from the host animal. Pinworm infections are the most common helminth infection that occurs in the US. The US Centers for Disease Control and Prevention (CDC) estimates about 40 million people are infected with pinworms currently in the US.
Who is at risk for getting pinworms?
Pinworm is the most common worm infection in the United States, and the majority of pinworm infections worldwide occur in temperate climates.
Pinworms in children
School-age children have the highest rates of pinworm infection. They are followed by preschoolers. Institutional settings including day care facilities often harbor cases of pinworm infection. Sometimes, nearly half of the children may be infected.
Pinworms in adults
Pinworm infection often occurs in more than one family member. Adults are less likely to have pinworm infection, except for mothers of infected children. However, adult sexual partners can transfer the eggs to each other.
