What is the Definition of Eczema?
Eczema, also known as atopic dermatitis, is a common, chronic inflammatory skin condition. It's characterized by itchy, dry patches of skin that may appear red, rough, and sore. Eczema is not contagious.
Eczema isn't a single disease but rather a group of inflammatory skin conditions. The key symptoms include:
- Itchiness: This is often the most prominent symptom, leading to scratching and potential skin damage.
- Dry skin: Affected areas tend to be dry and flaky.
- Rashes: Red, inflamed patches are common.
- Scaly patches: The skin may appear scaly or thickened.
- Blisters: In some cases, small, fluid-filled blisters can develop.
- Skin infections: Scratching can increase the risk of secondary skin infections.
The symptoms can be triggered or worsened by contact with irritants or allergens. While there's no cure, various treatments are available to manage symptoms and improve quality of life. These may include topical creams, ointments, and in some cases, oral medications.
Several reputable sources define eczema as follows:

- National Eczema Association: States that "Eczema (eg-zuh-MUH) is the name for a group of inflammatory skin conditions that cause itchiness, dry skin, rashes, scaly patches, blisters and skin infections." https://nationaleczema.org/eczema/
Prevalence estimates vary, but studies suggest that eczema affects a significant portion of the population, particularly children.
