The signs and symptoms commonly experienced by individuals are dry skin, itching (sometimes severe) along with redness of the affected area (usually in arms, legs, chest, neck and knees). The skin becomes thick, cracked, red and scaly after itching.

Atopic dermatitis is diagnosed by a physical examination of the affected area and by thorough review of medical history of the patient. The presence of red, scally and itchy skin confirms the condition of atopic dermatitis.

Since there is no cure for atopic dermatitis, the treatment can last for longer periods. However, with proper precautionary care, one can prevent the episodes of flare-ups by avoiding triggers, such as soap, detergents, some fabrics and perfumes. These trigger factors (sometimes it can vary from individuals) must be identified and avoided under proper medical supervision.

Skin allergies, mainly urticaria, are characterised by red, itchy raised areas of skin and can occur anywhere in the body suddenly after coming in contact with any substance, either food or otherwise. Atopic dermatitis consists of scaly, itchy rashes that affect, usually, the face, hands or knees. These rashes are not elevated and last for a longer period.

Atopic dermatitis is not known to be contagious. Therefore, it cannot spread from infected person to a healthy person by touching, hugging, etc. It usually appears to be genetic in nature.
