Infected Eczema in Children

How to recognise infection early — and when to seek urgent medical care.

Children with eczema have a weaker skin barrier, and scratching can create tiny breaks that allow bacteria or viruses to enter. This can turn a regular flare into infected eczema, which often worsens quickly and needs prompt treatment.

This page explains:

  • the common signs of bacterial infection (impetigo)
  • the important (but less common) viral infections to watch for
  • what you can do at home, and
  • when to seek urgent help.

Key takeaways

  • Infected eczema often looks different from a normal flare: weeping, crusting, pain, rapid spread
  • Yellow “honey” crusts suggest impetigo (bacterial infection)
  • If a child becomes unwell, has fever, or redness is spreading quickly, seek review promptly
  • Painful blisters or eczema suddenly becoming very painful can be urgent (possible eczema herpeticum)
  • Infection prevention matters: daily routine , triggers , medications , wet wraps , and eczema baths

Why infection is more common in eczema

Eczema skin is “leaky” and inflamed. Scratching damages the barrier further, making it easier for:

  • bacteria (especially Staphylococcus aureus) to overgrow
  • viruses (like herpes simplex) to enter through broken skin
  • and sometimes yeast to contribute to inflammation. (1–3)

This is why infection control and barrier repair go together.

1) Bacterial infection: impetigo / infected eczema

What it can look like

Bacterial infection often causes:

  • weeping or ooze
  • yellow or “honey-coloured” crusts
  • pimples/pustules or small pus bumps
  • increased redness and swelling
  • skin becoming more tender than usual
  • flare worsening suddenly rather than gradually (1–3)

What to do

If it looks mild and localised:

If there is significant crusting, rapid spread, pain, fever, or your child seems unwell — it often needs medical review and may require prescription topical or oral antibiotics. (1–3)

Important: If your child’s eczema is frequently crusting/infected, prevention strategies can help eczema bath; sometimes bleach is used for infection-prone eczema). (1,4)

2) Viral infection: eczema herpeticum (urgent)

Eczema herpeticum is a serious viral infection caused by herpes simplex virus spreading into eczema-affected skin. It can become severe quickly and needs urgent medical assessment. (2,5)

Red flags for eczema herpeticum

Seek urgent care the same day if you see:

  • clusters of painful blisters or small “punched-out” sores
  • eczema suddenly becoming very painful (pain is a key clue)
  • fever, lethargy, or child appears unwell
  • rapidly spreading lesions
  • involvement near the eyes (2,5)

Treatment usually requires antiviral medication promptly (e.g., aciclovir), and sometimes hospital assessment depending on severity. (2,5)

3) Molluscum and warts in eczema-prone skin

Children with eczema often get molluscum contagiosum and warts more easily because breaks in the skin barrier help viruses spread.

  • Molluscum bumps can trigger surrounding eczema (“molluscum dermatitis”) and lead to intense itch. (6)
  • Warts can spread more quickly when children scratch or when skin is inflamed.

What you can do at home (safe steps)

If you suspect infection:

When to seek urgent care (use this as your checklist)

Seek urgent medical review if:

  • your child has fever or seems unwell
  • redness is spreading quickly or the skin is hot and painful
  • there is significant pus, weeping, or crusting
  • your child has painful blisters or eczema suddenly becomes very painful (possible eczema herpeticum)
  • there is swelling or infection around the eyes
  • your child is very young and infection is suspected
  • you are worried — infection can escalate quickly in eczema (1–3,5)

FAQ

Can infected eczema heal on its own?

Mild cases sometimes improve, but infections can worsen quickly in eczema. If there is spreading redness, significant crusting, pain, or fever, it should be reviewed.

Are bleach baths helpful for infection-prone eczema?

They can be. Bleach baths are used in some children with recurrent infected flares as part of a broader plan. See Eczema Baths for Children for the RCH-style eczema bath approach.

Should we stop steroid creams if eczema is infected?

Not always. Sometimes inflammation still needs treatment while the infection is treated — but this depends on the type and severity of infection. If infection is suspected, seek review for a clear plan.
