This is why they are often called seatworms. They often attach themselves to the soiled linen in this region. According to Dr. Brooks, the worms deposit their eggs mostly at night, contaminating pajamas and bed linen. The eggs are readily transported through the air, and it is not uncommon to find them in every room of the house. In other words, the eggs of the pinworm are disseminated by air currents.
Infection occurs by wearing clothes or sleeping in the bed of an infected person.
You can also get the pinworm by handling pets. Pinworms are often found within the appendix and have been associated with acute and chronic inflammation. Heavy infestations of pinworms can cause insomnia, nausea, mental depression, and anorexia. Complications are much more common in women than in men. This stems from the fact that the female worm, after depositing her eggs, loses her way while trying to return to the colon.
