Impetigo is a very common, contagious, bacterial skin infection. It is most common in young children and is seen on the face.
What causes impetigo?
- Breaks in the skin barrier such as cuts, burns or eczema

How is impetigo diagnosed?
Diagnosis is usually based on symptoms and examination.
During an online GP consultation, we can:
- Assess symptoms and risk factors
- Provide treatment advice or prescriptions if needed
NB. You may need in-person assessment if the diagnosis is unclear and a physical examination/ skin swab is required.
When to seek urgent medical help
Go to A&E or seek urgent help if you have:
- Immunosuppression (a weakened immune system) and the rash is widespread
- You are unwell in yourself, and ‘sepsis’ is suspected
- The rash starts to look different or is rapidly spreading
What are treatment and management options for impetigo?
Self-Care and Home Management
Impetigo will usually get better by itself within 3 weeks.
It is important to take measures to prevent the spread of impetigo to other areas of the body and to other people. Some tips on how to prevent spread:
- do not share towels/ pillow cases – was at a high temperature after each use
- avoid touching or scratching the rash
- avoid contact with newborn babies, anyone who is immunosuppressed or playing contact sports
- check school/ work exclusion policy
- wash your hands regularly
Treatment from a GP
A GP can help with:
- Confirming the diagnosis.
- Recommendations on treatment to speed up resolution- such as a hydrogen peroxide, antibiotic cream or antibiotic tablet.
- Treating any underlying skin issues such as eczema
- Advice on when symptoms may indicate complications.·
