Eczema is not contagious. It cannot be caught or spread through touching, hugging, sharing a home, or having close contact with someone who has it. Eczema is an inflammatory skin condition, not an infection.
The condition can cause dry, itchy, cracked, or inflamed skin. It is linked to problems with the skin barrier and the immune system, and it may also run in families. Scratching can further damage the skin and make symptoms worse.
Although eczema itself does not spread between people, broken or cracked skin can become infected with bacteria, viruses, or fungi. Some of these infections, including impetigo or certain viral infections, may be contagious. Increasing pain, warmth, swelling, pus, weeping, crusting, rapidly worsening redness, or fever can be signs that medical care is needed.
Regular moisturizing, avoiding known triggers, and following the prescribed treatment plan can help protect the skin barrier. A dermatologist should evaluate eczema that is severe, keeps returning, or may be infected. Avoid using antibiotics, antifungal products, or strong medicated creams without medical advice.
