Impetigo vs Other Common Skin Rashes

What Is Impetigo?

Impetigo is a bacterial skin infection that affects the outer layers of the skin.

It is usually caused by bacteria entering through damaged skin and is highly contagious.

Without treatment, impetigo can spread to nearby skin and to other people through close contact.

What Does Impetigo Look Like?

Impetigo often begins as small red sores, spots, or blisters.

The crusts are often described as looking similar to dried honey.

This appearance is one of the most recognisable signs of impetigo.

Impetigo vs Eczema

Eczema is a long-term inflammatory skin condition that causes dry, itchy, and irritated skin. While eczema can sometimes become infected, eczema itself differs from impetigo in several ways.

People with eczema may be more susceptible to developing impetigo because the skin barrier is often damaged.

Impetigo vs Cold Sores

Cold sores are caused by the herpes simplex virus and commonly develop around the lips.

Because both conditions can occur around the mouth, they are sometimes confused.

Impetigo vs Contact Dermatitis

Contact dermatitis occurs when the skin reacts to an irritant or allergen.

Contact dermatitis often causes redness, itching, dryness, and widespread irritation.

Unlike impetigo, contact dermatitis does not usually cause yellow crusting, oozing bacterial infection, or progressive spread through bacterial contamination.

Removing the trigger often helps improve contact dermatitis symptoms.

Impetigo vs Insect Bites

Insect bites can initially resemble early impetigo because both may start as small red spots.

Sometimes an insect bite can become infected, which may make it look more similar to impetigo.

Professional assessment can help determine the cause.

Impetigo vs Chickenpox

Chickenpox is a viral infection that causes a widespread blistering rash.

Impetigo is generally more localised and commonly affects the face.

Although both conditions can blister, their overall appearance is usually quite different.

Signs That Suggest It Could Be Impetigo

Several features make impetigo more likely.

If these symptoms are present, impetigo becomes more likely than many other common skin conditions.

When Should You Seek Treatment?

You should seek advice if symptoms suggest impetigo, if the rash is spreading, or if the diagnosis is unclear.

Prompt assessment can help confirm the cause and determine whether treatment is required.
