Impetigo is a skin infection that is common in school-aged children. Impetigo appears as flat, yellow, crusty or moist patches or blisters on the skin, usually on the face, arms and legs. The sores can measure 5mm or more. Impetigo spreads easily.
Impetigo is caused by 2 bacteria, Staphylococcus and Streptococcus. These germs often live harmlessly on and in the body, such as on the skin and in the nose. Cuts, abrasions, or dry and cracked skin can allow them to get into deeper layers of the skin and cause infections. However, healthy, intact skin can sometimes develop sores.
How it spreads
The sores are filled with the germs, which spread when others touch the sores or infected fluid. Because the sores can be itchy or painful, people can scratch or touch them, spreading the infection via their hands to other parts of their body or to other people. The infection also spreads by touching contaminated clothing or other items.
Exclusion period
Exclude until antibiotic treatment has started.
Cover any sores on exposed skin with a waterproof dressing (like a plastic adhesive strip).
Actions for educators and other staff
Ensure staff and children have good hand hygiene.
Ensure staff use appropriate cleaning practices, as described in the Staying healthy guideline.
Actions for parents and carers
Keep your child at home until they have had antibiotics for at least 24 hours. If antibiotics are not used, keep the child at home until the sores are dry.
Cover any sores on exposed skin with a waterproof dressing (like a plastic adhesive strip).
Make sure your child washes their hands thoroughly and often, especially if they touch the sores.
