Crusted or oozing sores around the nose, mouth, or other areas can spread quickly between children.
We look at the extent, symptoms, and whether a deeper infection is present before deciding what treatment is needed.
We also explain hygiene, school or daycare considerations, and signs that should prompt follow-up.

How is it treated?
A clinician can usually diagnose impetigo by examining the skin. A few localized sores may be treated with a prescription topical antibiotic; more extensive disease may need an oral antibiotic. Use the medicine for the prescribed course.
Reducing spread
- Wash hands and avoid picking at sores.
- Keep affected skin clean and cover exposed sores.
- Do not share towels or clothing.
- Ask about return-to-school timing after treatment starts and follow school rules.
Could it be a deeper infection?
Spreading warmth, swelling, increasing pain, or fever needs prompt medical assessment for problems such as cellulitis. A pus-filled lump may be an abscess; do not squeeze it.
