Factors that contribute to the increased infections in atopic dermatitis (AD) are skin barrier defects, suppression of cutaneous innate immunity by type 2 inflammation, Staphylococcus aureus colonization, and cutaneous dysbiosis. Skin infections in AD increase the risk of life-threatening systemic infections.
Can atopic dermatitis get infected?
What is infected eczema? 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.
Does eczema increase risk of infection?
An eczema rash is also typically very itchy, which will cause you to scratch your skin. Scratching your skin can cause small breaks in the skin, which increases the risk of it becoming infected since bacteria and viruses can more easily enter the body.
What infection causes 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.
Does dermatitis affect your immune system?
Atopic dermatitis is an immunological disease, which means it involves the immune system. With atopic dermatitis, your immune system is highly sensitive and can react to even the smallest allergens or irritants. This can cause inflammation underneath your skin, which may lead to frequent flare-ups.
Is atopic dermatitis a bacterial infection?
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.
What is infected eczema called?

Is atopic dermatitis a comorbidity?
Atopic dermatitis is associated with substantial burden and comorbidities. Identifying AD comorbidities is essential for proper disease management and improving overall patient outcomes. Atopic dermatitis (AD) impacts all aspects of patients’ quality of life and emotional well-being.
What is the underlying cause of eczema?
We don’t know what exactly causes eczema. However, for most types of eczema, researchers believe a combination of genes and triggers are involved. People with eczema tend to have an over-reactive immune system that when triggered by a substance outside or inside the body, responds by producing inflammation.
What are the complications of dermatitis?

Unlike cellulitis, most forms of dermatitis are the result of allergic reactions, not bacterial infections.
Is atopic dermatitis an autoimmune disorder?
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 at the molecular level.
Why is my atopic dermatitis spreading?
