In a child with enterobiasis, which finding is expected?

In a child with enterobiasis, intense perianal itching is a hallmark symptom. This condition, commonly caused by the pinworm Enterobius vermicularis, results in female pinworms migrating to the anal region to lay their eggs, which is the source of the discomfort and itching. This itching often becomes particularly noticeable at night, leading to significant restlessness or irritability in affected children.

Other symptoms associated with enterobiasis might include mild abdominal pain or secondary bacterial infections due to scratching, but intense perianal itching is the most directly associated and characteristic finding. The other options—constipation, high fever, and frequent urination—are not typically associated with enterobiasis and can suggest different medical issues or conditions.
