Eczema vs Impetigo Australia: Telling School Sores From a Flare
Eczema vs impetigo is mostly a question of crusting and contagion. Eczema is dry, itchy and not catching. Impetigo — school sores — produces golden or honey-coloured crusts over weeping sores, spreads quickly across the skin and to other people, and needs antibiotics. The two often occur together, because cracked eczema skin is exactly where the bacteria get in.
At a Glance
- Honey-coloured or golden crusting is the signature of impetigo, not of ordinary eczema
- Impetigo is highly contagious; eczema is not catching at all
- Sores commonly appear around the nose, mouth, hands and legs, and spread by touching and scratching
- Eczema and impetigo frequently coexist — dry, cracked, scratched skin is the usual entry point
- Australian exclusion rules apply: children stay home until antibiotic treatment has started, with exposed sores covered
What Does Eczema vs Impetigo Actually Look Like?
Ordinary eczema is dry. It scales, flakes, thickens where it has been rubbed, and itches persistently. It sits in familiar places and follows a pattern you recognise. It does not produce golden crusts, and it does not pass to anyone else.
Impetigo behaves differently from the start. As Victoria's Department of Health describes it, the infection usually begins as small flat spots that develop into fluid-filled blisters or pustules, which then burst and leak fluid that dries into honey-coloured crusts. The responsible bacteria are Staphylococcus aureus and, less commonly, Streptococcus pyogenes, and while infants and young children are most affected, anyone can get it.
The Australian name is school sores, which tells you most of what you need to know about how it moves through a classroom. Sores tend to appear on exposed skin — around the nose and mouth, on the hands, on the legs — and are often more than a centimetre across.
The tell that matters most for anyone managing eczema is the crust colour. Weeping eczema produces clear or slightly cloudy fluid. Golden, sticky, varnish-like crusting is a bacterial signature and is worth a same-week appointment even if nothing else has changed.
Speed is the second tell. Eczema shifts over days and weeks. Impetigo can spread visibly across a cheek in a day, and new sores appear away from the original site because the bacteria travel on fingers.
Why Eczema vs Impetigo Is Not Always Either-Or
This is the part most comparisons get wrong by treating it as a choice between two diagnoses. Very often it is both.
Cuts, abrasions and dry, cracked skin let these bacteria reach the deeper layers where they cause infection — which describes eczema-affected skin precisely. Scratching breaks the surface, the bacteria are frequently already living on the skin harmlessly, and an ordinary flare becomes an infected one. Clinicians call this impetiginised eczema.
So the useful question is often not "is this eczema or impetigo" but "has this eczema become infected". Our guide to signs a flare has become infected covers what changes: crust colour, spread beyond the usual pattern, and weeping that has altered in character.
It matters for reassurance in the other direction too. Parents often worry that a child's eczema is contagious, and it is not — the question of whether eczema itself can spread has a clear answer. What can spread is a bacterial infection sitting on top of it.
One practical consequence: if a child with eczema keeps developing crusted sores, managing the underlying eczema well is part of preventing recurrence, because intact skin is much harder for bacteria to colonise. That is a conversation for the GP rather than a reason to change products on your own.
What Are the School and Childcare Rules in Australia?
This is the question that usually brings parents looking, and there is a clear national answer. The national guidance for childcare and schools is to exclude until antibiotic treatment has started, and to cover any sores on exposed skin with a waterproof dressing before returning.
States word this slightly differently. Queensland's health department specifies exclusion until the day after treatment begins, with exposed sores covered until they are dry, so it is worth checking your own state or simply asking the school. The common thread across all of them is that treatment must be underway and exposed sores must be covered.
Treatment itself is prescription territory. A doctor may recommend an antibiotic cream for mild, localised sores, with oral antibiotics used where there are multiple sores or the infection keeps returning. Nothing over the counter substitutes for that, and the sores remain infectious while they are still discharging.
Household measures are worth taking seriously alongside treatment: separate towels and face washers, frequent hand washing, keeping fingernails short, and washing clothing and bedding that has been in contact with the sores. For families already managing flares at school, our parent's practical guide to school and eczema covers the broader conversation with teachers.

FAQ
Is impetigo just infected eczema?
Not quite. Impetigo is a specific bacterial skin infection that can occur on otherwise healthy skin. Infected eczema is a flare that bacteria have colonised. They overlap heavily, look similar, and are both treated with antibiotics — which is why a doctor makes the call rather than a checklist.
How contagious is it really?
Very. It spreads by direct contact with the sores or their fluid, and indirectly through towels, clothing, bedding and toys. Scratching moves it to new sites on the same child and onto other people via their hands.
Can adults get school sores?
Yes. It is most common in infants and young children, but people of any age can get it. Adults with eczema, cuts or cracked skin are more susceptible than adults with intact skin.
What does honey-coloured crusting actually look like?
Golden or amber, sticky when fresh and varnish-like when dry, sitting on top of a moist or raw patch. It differs from the pale, dry flaking of ordinary eczema and from the clear fluid a weeping flare produces.
Should I use my child's eczema cream on the sores?
Ask a doctor or pharmacist first. A steroid cream is not treatment for a bacterial infection, and applying one before assessment can make the sores harder to interpret. Moisturising unaffected skin is a separate matter.
How long until my child can return to school?
The national guidance is once antibiotic treatment has started and exposed sores are covered with a waterproof dressing. Some states specify the day after treatment begins. Confirm with your school or state health department.
Does impetigo leave scars?
It generally settles without scarring when treated, though temporary marks or colour change can persist for weeks — longer on darker skin. Scratching and picking increase the chance of a lasting mark.
Can it become something more serious?
Untreated, it can extend into the deeper tissue as cellulitis, which is a more serious infection. This is uncommon with prompt treatment, and it is the main reason not to wait it out.
Key Takeaways
- Golden, honey-coloured crusting over weeping sores is the impetigo signature; dry scaling and itch is eczema
- Impetigo is highly contagious and eczema is not, which is the difference that changes household behaviour
- The two coexist often — cracked, scratched eczema skin is the usual entry point for the bacteria
- Antibiotics are required, so a GP or pharmacist visit is the necessary step, not a product change
- Children stay home until treatment has started, with exposed sores covered; check your state for the exact wording
When to Seek Medical Advice
See a GP if crusted, golden or weeping sores appear, if a rash is spreading rapidly across the skin or to other people in the household, or if a familiar eczema flare has changed character with yellow crusting or pus. This infection needs antibiotic treatment and will not settle with moisturiser or a steroid cream.
Seek same-day assessment if a child develops fever, becomes generally unwell, or if the surrounding skin becomes hot, swollen, painful and increasingly red — that can indicate the infection has extended deeper. In an emergency, call 000.
Also see a doctor if sores keep coming back, if they are not improving after several days of prescribed treatment, or if new sores appear despite it. Healthdirect sets out symptoms and treatment in plain language, and you can call them on 1800 022 222 to speak to a registered nurse.
Australian Psoriasis and Eczema Supplies stocks fragrance-free moisturisers and gentle cleansers for everyday eczema care, which is separate from the treatment of any bacterial skin infection.
