Which of the following is a common sympton of eczema in children?

Dry, itchy skin is a hallmark symptom of eczema, also known as atopic dermatitis, particularly in children. Eczema often presents with patches of dry, inflamed skin that can be quite uncomfortable and lead to significant itching. This intense itchiness can result in scratching, which may further irritate the skin and exacerbate the condition, leading to a cycle of discomfort and inflammation. The characteristic dry, flaky appearance of the skin includes areas that may become red or swollen, indicating an inflammatory response.

In contrast, excessive sweating is not typically associated with eczema; it might aggravate existing skin conditions but is not a direct symptom of eczema itself. Frequent nosebleeds are unrelated to eczema, as they more commonly stem from factors like dry air or allergies. A persistent cough doesn't connect to eczema either, as it typically involves respiratory issues rather than dermatological conditions. Understanding these common symptoms can help in identifying eczema and differentiating it from other health concerns.
