A common symptom of Enterobiasis?

• A. Nausea
• B. Severe itching
• C. Cough
• D. Rash

Answer: (B)

Enterobiasis is caused by pinworms, and the most characteristic sign is intense perianal itching caused by the female worms laying eggs around the anus, usually at night. This itching leads to scratching, which can cause irritation and sleep disturbance in children. Among common symptoms, severe itching around the anal area best fits the typical presentation of this infection. Nausea, cough, and rash can occur with other conditions, but they are not the defining feature of pinworm infection. A simple tape test in the morning is a common way to diagnose it, and treatment includes antiparasitic medication plus hygiene practices to prevent reinfection.
