Impetigo — Conditions

What is Impetigo?

A contagious bacterial skin infection caused by Staphylococcus or Streptococcus

Most common in children, blisters rupture to form honey-colored crusts. It spreads easily through contact.

Caution

Antibiotics from a doctor are required. Do not share towels.

Main causes & characteristics

Impetigo is known to occur when Staphylococcus or Streptococcus bacteria penetrate the skin through small cuts, insect bites, or areas affected by eczema. It is most common in children and can spread easily through hand contact or shared towels. It tends to appear more frequently in environments with poor hygiene or in hot, humid conditions.

How to manage

It is recommended to avoid touching the honey-colored crusts that form after blisters rupture, and to use separate towels and personal hygiene items from other household members. Proper hygiene — washing hands frequently and keeping the affected area clean — is important. As impetigo is contagious, consulting a dermatologist is recommended if it spreads or is accompanied by fever.

Good to know alongside

Impetigo is often discussed alongside bacterial skin infections, folliculitis, and cellulitis. It may also be mentioned as a complication in individuals with atopic dermatitis.

Everyday care tips

Keeping fingernails trimmed short to prevent spreading the infection to other areas by scratching, and frequently washing a child's hands and towels, may help manage impetigo.
