Non-bullous impetigo: what to know

Non-bullous impetigo is the common crust-forming pattern of impetigo. The spots may begin around the nose and mouth, on the hands, or where skin has been scratched, bitten, or irritated. They can enlarge as nearby spots join. A person may have little discomfort, although itching can lead to scratching and further spread. Similar crusting can occur with eczema or other skin conditions, so appearance alone does not confirm the diagnosis.

Clean the affected skin gently with lukewarm water, pat it dry, and cover open areas with a clean dressing. Wash hands after contact, avoid scratching, and keep nails short. Use separate towels, clothing, bedding, and washcloths until the infection has been assessed and treatment advice is complete. A clinician may prescribe [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) for a limited area or another option when lesions are more widespread.

Arrange medical review if new lesions keep appearing, the area is spreading, there is increasing tenderness, or the skin is not improving with prescribed care. Seek urgent help for fever, severe pain, rapidly expanding redness, marked swelling, or unusual weakness. These signs can suggest a more extensive infection and may require [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/).

Ask how non-bullous impetigo differs from infected eczema, whether lesions should stay covered, when close contacts can safely share items again, and what changes should trigger reassessment.
