There are intestinal parasites called pinworms (Enterobius vermicularis). Their appearance is more common during childhood. They are small white worms that can cause an itchy sensation, especially at night, which often interrupts the child’s rest.
For this reason, it is extremely important to learn how the infection occurs and how to prevent it; this is key to managing this problem properly. The infection begins when the microscopic eggs of the parasite are ingested. These can be found on toys, bedding, household surfaces, or even under fingernails.
Once inside the body, this is the incubation process that pinworms follow:
Ingestion of the eggs: The eggs reach the small intestine through the mouth.
Maturation: There they hatch and develop, and later the adult parasites reside in the large intestine.
Night migration: During the night, the females move to the outer skin to lay their eggs.
This is why children wake up claiming to feel itchy, as this process can cause irritation and itching in the affected area, leading the child to scratch frequently, especially while sleeping.
Scratching increases the risk of spreading the infection to other children because it causes the eggs to stick to the fingers and accumulate under the nails. This makes it easier for them to spread to other objects or for the child to unknowingly ingest them again, restarting the infection cycle.
There is a peculiarity in this parasite, and that is that the eggs can survive in the environment for several days, which makes it important to maintain proper hygiene habits to prevent the infection from spreading to other members of the household.
