What symptom is usually associated with a pinworm infection?

• A. Itching around the anus
• B. Chest pain
• C. Nausea
• D. Headaches

Answer: (A)

Itching around the anus is a hallmark symptom of a pinworm infection, also known as enterobiasis. This condition is caused by the parasite Enterobius vermicularis, which is commonly found in children. The female pinworm migrates to the anal area at night to deposit her eggs, which often leads to irritation and intense itching. This itching can cause significant discomfort and may lead to scratching, increasing the risk of secondary bacterial infections. While other symptoms like nausea, chest pain, or headaches may arise from a variety of conditions or other infections, they are not typically associated with pinworm infections specifically. Thus, the notable symptom of itching around the anus distinctly identifies this type of parasitic infection.
