Show me impetigo: what to know

Impetigo commonly affects the face, around the nose and mouth, or areas where skin has been scratched, but it can occur elsewhere. It may start as a small blister, red patch, or oozing sore before a yellow-brown crust develops. Crusting Skin can be a clue, though eczema, insect bites, and other infections may look similar.

The bacteria can pass through direct contact, shared towels, clothing, bedding, or contact with fluid from a sore. A child or adult with atopic dermatitis may have more opportunities for bacteria to enter through irritated or broken skin. Avoid touching sores and wash hands after applying any treatment.

Arrange a clinical assessment, especially when sores are spreading or recurring. Gently cleanse the area, pat it dry, cover it with a clean dressing if practical, and wash hands before and after contact. Do not share towels, razors, clothing, or bedding; launder used fabrics and keep fingernails short to reduce scratching.

Treatment depends on how widespread the infection is and where it appears. Topical Antibiotic Therapy may be used for selected localised sores, while Antibiotics For Skin Infection may be considered when infection is more extensive or needs treatment beyond the skin surface. Use prescribed medicine for the instructed course and do not share it.

Seek prompt medical care if sores spread quickly, involve the eyes, cause marked pain or swelling, or occur with fever or feeling very unwell. Urgent advice is needed for facial swelling, severe headache, or eye symptoms. Contact a clinician if the infection is not improving with prescribed treatment or if several household members develop similar sores.

Ask whether the sores are consistent with impetigo, how to clean and cover them, and when it is safe to return to close contact with others. Tell the clinician about eczema, recent skin injury, medicine allergies, and anyone else at home with crusted or oozing lesions.
