Impetigo vs Eczema: Key Differences
Content reviewed against published AAP, AAD, NICE guidelines
Last reviewed:
Impetigo and eczema can look similar — both cause red, crusty patches on the skin. However, impetigo is a contagious bacterial infection that needs antibiotics, while eczema is a chronic inflammatory condition. Eczema can also become infected with impetigo (impetiginized eczema).
Key takeaways
- Honey-colored (golden) crusting is the hallmark of impetigo; eczema has dry/silvery scaling
- Impetigo is contagious and spreads rapidly to others; eczema is never contagious
- Impetigo clears with antibiotics; eczema is chronic and managed long-term
- Impetigo often starts near the nose/mouth; eczema favors skin creases
: Cause
Impetigo: Bacterial infection (Staph aureus or Group A Strep)
Eczema (Atopic Dermatitis): Chronic immune/skin barrier dysfunction (genetic + triggers)
: Appearance
Impetigo: Honey-colored or golden crusts on red base; may have fluid-filled blisters
Eczema (Atopic Dermatitis): Dry, red, rough, scaly patches; may crack or weep when severe
: Contagious
Impetigo: Highly contagious via direct contact or shared items
Eczema (Atopic Dermatitis): Never contagious
: Location
Impetigo: Face (around nose and mouth), hands, areas of broken skin
Eczema (Atopic Dermatitis): Creases (elbows, knees, wrists); cheeks in babies
: Itch
Impetigo: Mildly itchy
Eczema (Atopic Dermatitis): Intensely itchy, especially at night
: Onset
Impetigo: Develops over days; often starts at site of break in skin
Eczema (Atopic Dermatitis): Chronic; flares triggered by irritants, allergens, stress, weather
: Spread
Impetigo: Spreads to new areas by touching/scratching (auto-inoculation)
Eczema (Atopic Dermatitis): Does not spread by contact; patches appear in typical locations
: Treatment
Impetigo: Topical or oral antibiotics
Eczema (Atopic Dermatitis): Moisturizers, topical steroids, avoiding triggers
: Crust color
Impetigo: Golden/honey-colored crust (classic sign)
Eczema (Atopic Dermatitis): White/silver flaking or clear weeping (no golden crust unless infected)
| Impetigo | Eczema (Atopic Dermatitis) | |
|---|---|---|
| Cause | Bacterial infection (Staph aureus or Group A Strep) | Chronic immune/skin barrier dysfunction (genetic + triggers) |
| Appearance | Honey-colored or golden crusts on red base; may have fluid-filled blisters | Dry, red, rough, scaly patches; may crack or weep when severe |
| Contagious | Highly contagious via direct contact or shared items | Never contagious |
| Location | Face (around nose and mouth), hands, areas of broken skin | Creases (elbows, knees, wrists); cheeks in babies |
| Itch | Mildly itchy | Intensely itchy, especially at night |
| Onset | Develops over days; often starts at site of break in skin | Chronic; flares triggered by irritants, allergens, stress, weather |
| Spread | Spreads to new areas by touching/scratching (auto-inoculation) | Does not spread by contact; patches appear in typical locations |
| Treatment | Topical or oral antibiotics | Moisturizers, topical steroids, avoiding triggers |
| Crust color | Golden/honey-colored crust (classic sign) | White/silver flaking or clear weeping (no golden crust unless infected) |
When to Worry
- Golden/honey-colored crusting on eczema patches (likely secondary impetigo infection — needs antibiotics)
- Rapidly spreading red, warm, swollen area (possible cellulitis)
- Fever with skin infection (suggests deeper infection)
- Painful, pus-filled blisters (bullous impetigo)
- Eczema not improving with usual treatment (consider secondary infection)
- Dark or tea-colored urine 1-2 weeks after impetigo (rare kidney complication)

Bottom line
Both Impetigo and Eczema (Atopic Dermatitis) are common in young children. The key differences in symptoms can help you identify what your child may have, but when in doubt, consult your pediatrician.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
