PubMed was searched for English-language research articles, systematic reviews, meta-analyses and guidelines published until February 2023 using the key term \"atopic dermatitis\" and terms relevant to infections. Patients with AD have an increased risk of bacterial, viral and fungal infections of the skin, mainly due to impaired barrier function, altered immune response and frequent scratching. The most common pathogens are Staphylococcus aureus and herpes simplex virus, which can cause impetigo, folliculitis, abscesses, eczema herpeticum and other complications. They also appear to increase susceptibility to systemic infections, including respiratory and urinary tract infections and sepsis. Certain systemic treatments for AD, such as mycophenolate mofetil and Janus kinase inhibitors, increase the risk of viral infections.
