Atopic dermatitis (AD) is the most common allergic skin disease in the general population. It is a chronic inflammatory skin disease complicated by recurrent bacterial and viral infections that, when left untreated, can lead to significant complications.
Eczema (atopic dermatitis) is a type of skin inflammation that can cause a variety of symptoms, from an itchy red rash to patchy sores. Open sores — especially from scratching eczema — can allow viruses, bacteria, and fungi to enter the skin. This can result in an infection.
What type of infection is dermatitis?
Dermatitis is a general term for conditions that cause inflammation of the skin. Examples include atopic dermatitis (eczema), contact dermatitis and seborrheic dermatitis (dandruff). These conditions cause red rashes, dry skin and itchiness among other symptoms.
Is dermatitis a bacterial skin disease?
Patients with atopic dermatitis (AD) have an increased risk of bacterial skin infections, which cause significant morbidity and, if untreated, may become systemic. Staphylococcus aureus colonizes the skin of most patients with AD and is the most common organism to cause infections.
Can viruses cause dermatitis?
Two other viruses that can cause problems for eczema patients are Molloscum contagiosum and Vaccinia. This last virus may cause severe skin reactions (eczema vaccinatum) in individuals with active, but even past histories of, atopic dermatitis after immunization against smallpox with vaccinia.
Do you get fever with dermatitis?
If a person has chronic eczema flares, they should see their doctor if they develop a fever, experience chills, have low energy, or show signs of infection, such as oozing blisters and excessive itchiness.
Can antibiotics help dermatitis?
Don’t use oral antibiotics for treatment of atopic dermatitis unless there is clinical evidence of infection. Rationale and Comments: The presence of high numbers of the Staphylococcus aureus (staph) bacteria on the skin of children and adults with atopic dermatitis is common.
What triggers dermatitis?
A common cause of dermatitis is contact with something that irritates your skin or triggers an allergic reaction — for example, poison ivy, perfume, lotion and jewelry containing nickel.

Is dermatitis an autoimmune disease?
For the first time, a team led by researchers at the Icahn School of Medicine at Mount Sinai has proven that atopic dermatitis, also known as eczema, is an immune-driven (autoimmune) disease.
Can dermatitis become infected?
Occasionally, areas of skin affected by contact dermatitis can become infected. Signs of an infection can include: your existing symptoms getting rapidly worse. discharge from your skin.
What happens if dermatitis is untreated?
When left untreated, contact dermatitis can develop into an escalating cycle of itching, scratching and inflammation. In some cases, the excessive scratching can introduce bacteria or fungus into layers of the skin, resulting in infections that can be serious in some people.
Dermatitis is a general term for a swollen skin rash that covers many conditions. These include atopic dermatitis, or eczema, and contact dermatitis, an allergic reaction to an irritating substance. Unlike cellulitis, most forms of dermatitis are the result of allergic reactions, not bacterial infections.
Viral skin infections are a wide group of conditions. They can be a reaction to a virus inside your body, or they can be an actual infection of your skin. They range from the entirely harmless, to the quite serious (but not usually life-threatening). Some are contagious; others you can touch without catching.
What infections cause atopic dermatitis?
The most common skin infections in AD are caused by Staphylococcus aureus (S. aureus) and herpes simplex virus (HSV). In the absence of clinical signs of infections, the majority of AD patients are also colonized with S. aureus on their skin lesions.
