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.
