Cellulitis in Children: Early Awareness, Risk Factors & Prevention

What is cellulitis?
Cellulitis is a bacterial infection of the deeper layers of the skin and underlying tissues. It develops when bacteria enter through a break in the skin, such as a cut, scrape, bite, or cracked area.

Canadian first aid & caregiver relevance
Cellulitis can affect children of all ages and is often first noticed by parents, caregivers, educators, or childcare staff. Early awareness of skin changes helps ensure timely medical assessment when needed.

Scenario: Playground scrape

After falling at the playground, a toddler had a small scrape on the lower leg. A few days later, the area appeared red and warm and seemed to be spreading. A caregiver arranged medical evaluation, and the child recovered with appropriate care.

Common areas affected

Cellulitis often appears on:

• Lower legs and feet

• Arms or hands

• Face (less common in children)

However, it can develop anywhere the skin barrier is compromised.

Signs and symptoms to watch for

Cellulitis may involve:

• Redness that spreads over time

• Swelling or firmness of the skin

• Warmth in the affected area

• Skin tenderness or discomfort

• Fever or general unwellness in some cases

In young children, behaviour changes such as fussiness or reduced activity may also be noticed.

Common ways bacteria enter the skin

Cuts and scrapes
Minor skin injuries are common in toddlers as coordination develops. Even small breaks in the skin can allow bacteria to enter.

Animal bites or scratches
Bites from pets or animals can introduce bacteria beneath the skin surface, even when the wound appears small.

Insect bites
Scratching insect bites can break the skin, increasing infection risk.

Athlete’s foot or cracked skin
Peeling or cracked skin between the toes can create openings for bacteria, particularly on the feet.

Eczema or chronic skin irritation
Dry, itchy skin that cracks more easily can increase susceptibility to infection.

Chickenpox sores
Scratching or broken blisters during chickenpox can increase infection risk until healing occurs.

Prevention & everyday skin care awareness

General prevention principles include:

• Prompt attention to skin injuries

• Keeping skin clean and dry

• Avoiding scratching when possible

• Monitoring healing areas for changes

• Supporting healthy skin barrier care for children with eczema

These measures are especially important in childcare, schools, sports, and outdoor play settings.

When to seek medical assessment

Medical evaluation is important if:

• Redness spreads or worsens

• Swelling or warmth increases

• Fever develops

• Pain becomes significant

• A child appears increasingly unwell

• Cellulitis is suspected on the face or near joints

FAQ

Is cellulitis contagious?
No. Cellulitis itself does not spread person-to-person, but the bacteria that cause it can be shared through skin contact.

Can cellulitis start from a very small cut?
Yes. Even minor breaks in the skin can allow bacteria to enter.

Are children more at risk than adults?
Children experience more skin injuries, which can increase risk, but cellulitis can occur at any age.

Does redness always mean cellulitis?
No. Many skin reactions cause redness, which is why medical assessment is important when changes worsen or spread.
