Overview
Impetigo is a common and highly contagious bacterial skin infection, most often seen in young children. It causes sores and blisters that burst and form characteristic golden-brown or honey-coloured crusts, usually around the nose and mouth. It spreads easily through close contact and shared items, but is usually not serious and clears with treatment.
Symptoms
- Red sores or blisters, often around the nose, mouth, hands or other exposed skin
- Sores that burst and leave golden-brown or honey-coloured crusts
- Itching and sometimes mild soreness
- Spread to other body areas through scratching
- Occasionally fluid-filled blisters that are larger and last longer
Causes & risk factors
- Bacteria (commonly staphylococcus or streptococcus) entering through breaks in the skin
- Cuts, insect bites, eczema or other skin damage
- Close contact with an infected person or contaminated towels, clothing or toys
- Warm, humid conditions and crowded settings encourage spread
Treatment & self-care
Impetigo is treated with antibiotics, either applied to the skin or taken by mouth, as advised by a clinician. Good hygiene, not sharing towels, and keeping affected children away from school or nursery until no longer contagious help prevent spread. A doctor or pharmacist can guide diagnosis and treatment.
See a doctor urgently if
- You or your child develop crusted or blistering sores that may be impetigo
- The infection is spreading, not improving with treatment, or keeps coming back
- There is increasing redness, swelling, pain or fever
- Sores are widespread or the person has a weakened immune system
- You develop dark urine or swelling in the days after impetigo - seek prompt care
