Although they are tiny and usually easy to treat, their presence can cause significant discomfort—especially because of the nighttime itching that disrupts a child’s sleep and often the rest of the family’s as well.
Understanding how this parasite behaves and spreads is essential for detecting it early and breaking the cycle of infection.
How Pinworm Infection Begins
This parasitic infection usually starts with the accidental ingestion of microscopic eggs, so small they can’t be seen with the naked eye. These eggs can be found on everyday surfaces such as toys, bedding, tables, doorknobs, or even under fingernails, where they tend to stick easily.
Once the child ingests the eggs, they move to the small intestine, where they hatch and release the larvae. Over the following days, the parasites mature and settle in the colon, which becomes their home inside the body.
