What should you know about secondary impetigo?

Scratching, eczema, insect bites, or a break in the skin can make it easier for bacteria to enter. Small blisters or sores may ooze and form yellow-brown crusts, and nearby skin can become irritated. Atopic Dermatitis can create repeated barrier damage, so new crusting on an eczema patch may represent infection rather than an ordinary flare. Impetigo can spread through touch, towels, clothing, and shared personal items.

Have new sores assessed, especially when they spread or sit over an existing rash. Gently cleanse as advised, avoid picking crusts, keep lesions covered when possible, wash hands frequently, and use separate towels and linens. A clinician may recommend topical antibiotic therapy for limited disease or antibiotics for skin infection when broader treatment is needed. Follow the prescribed course and the advice about returning to school, work, or close contact.

Seek prompt care if sores spread quickly, become very painful, involve the eyes, produce increasing swelling, or accompany fever or unusual tiredness. Urgent assessment is appropriate for marked facial swelling, confusion, or a child who seems seriously unwell. Worsening crusting despite treatment may mean the diagnosis or treatment needs review.

Ask whether the underlying rash also needs treatment, how to clean and cover the area, how long it remains contagious, whether household contacts need advice, and what change should trigger review.
