I'm going to answer this question that many people have: is atopic dermatitis or eczema contagious? No, atopic dermatitis is not contagious. We do not know why it appears, although there's been newer and more research and investigation into its origin and pathogenesis. It has several risk factors, including a history of asthma and allergic rhinitis, family or personal history of eczema. It arises from a complex interaction of environmental and genetic influences, including a defective skin barrier. This makes the skin more sensitive to irritation from temperature changes, irritants like soaps and other harsh substances, and other non-specific triggers. Are there different types of eczema? Yes. There are many different types of eczema. I may not be able to remember or be able to cover all of them. However, there are some variations that we can discuss: papular eczema, hand and foot eczema, scalp eczema, et cetera. Eczema also varies depending on the age group involved, including infancy, childhood, adolescence, and adulthood. Regional variation can also occur with eczema, occurring exclusively sometimes in some areas such as the ears, eyelids, lips, head and neck, nipples, flexures, hands, and feet.
