What should you know about a rash similar to impetigo?

Impetigo can produce fragile blisters or moist sores that develop a yellow-brown crust, often around the nose, mouth, or on exposed skin. Atopic dermatitis may crack, ooze, and crust after scratching, while other causes of Crusting Skin can look alike. The location, speed of spread, pain, itch, fever, and whether anyone else is affected help a clinician separate infection from inflammation.

Wash hands after touching the area, cleanse gently, pat dry, and use a separate towel. Keep nails short and avoid picking. Do not share clothing, bedding, or personal items. Do not start leftover antibiotics or squeeze blisters; a clinician may recommend Antibiotics For Skin Infection or Topical Antibiotic Therapy only when the diagnosis and extent support it.

Arrange prompt medical review when crusting is spreading, sores are multiplying, the skin is hot or painful, or a child is unwell. Seek urgent care for fever with rapid progression, marked swelling near the eye, severe pain, dehydration, or a widespread blistering rash.

Ask whether the rash is infectious, how to limit spread at home, whether a swab is useful, and how to use any prescribed antibiotic safely.
