What is a common secondary infection in atopic dermatitis that can worsen the condition?

In the context of atopic dermatitis, bacterial infections are particularly common and significant. Atopic dermatitis, characterized by dry, pruritic skin, often leads to breaks in the skin barrier. This compromised barrier allows bacteria, especially Staphylococcus aureus, to colonize and proliferate on the skin. The presence of these bacteria can exacerbate the inflammation and irritation associated with atopic dermatitis, potentially leading to a more severe and widespread condition.

Management of atopic dermatitis often includes addressing these secondary bacterial infections, as they can worsen the eczema and complicate the overall treatment. The presence of bacterial infections may produce additional symptoms such as increased redness, warmth, and oozing from the affected areas, signaling a need for targeted antibiotic therapy in conjunction with the treatment of the dermatitis itself.

Other types of infections, while they can occur in patients with atopic dermatitis, are less common as complications in this specific context. Fungal infections, such as those caused by Malassezia, can arise, but they're not as frequent as bacterial infections. Viral infections do occur and may include herpes simplex virus, especially if there are excoriated lesions, but typically bacterial infections are the most prevalent issue linked to worsening atopic dermatitis. Parasitic infections are also
