Eczema is a common skin disease that can occur in both men and women, young and old, regardless of the season. Most patients are pruritic, with papules predominating in the acute phase and epidermal hypertrophy and mossy lesions in the chronic phase. Eczema can occur in any part of the body and is often symmetrically distributed. Common site-specific eczema includes ear eczema, hand and foot eczema, breast eczema, and eczema of the external anal genitalia. The symptoms of eczema are some red spots, blisters, papules and other polymorphs on the skin, often accompanied by itching. Many people think that eczema is caused by a decline in immunity or related to humidity, but in fact, eczema is generally easy to get for people with allergies. The most serious type of eczema disease is atopic dermatitis, also known as atopic dermatitis. If a child has severe eczema that is so severe that he cannot eat or sleep well, it can affect his growth and development, and he should be seen by a hospital in a timely manner. Is eczema hereditary? Is it contagious? Allergies can be inherited. If both parents have had eczema, the child will have a greater chance of getting eczema, which is not contagious.
