Impetigo
Impetigo is a common and highly contagious skin infection, especially prevalent among young children. It is primarily caused by bacteria—Staphylococcus aureus or Streptococcus pyogenes (group A strep)—that invade the skin through minor cuts, insect bites, or even healthy skin. The infection thrives in warm, humid conditions and spreads easily through close contact, shared items, or scratching.
what to know
The skin acts as a barrier to protect against bacteria, but when this barrier is compromised, bacteria can enter and multiply. In impetigo, the bacteria produce toxins that cause the top layers of the skin to blister and form characteristic lesions.
What to Look For:
Red sores or blisters: Often starting around the nose, mouth, hands, or diaper area.
Golden-yellow crusts: After the blisters burst, they form a honey-colored crust.
Itching and discomfort: Children may scratch, which can worsen the spread.
Swollen lymph nodes: Occasionally, nearby lymph nodes may become tender and swollen.
what to do
If your child has a single lesion:
Topical antibiotic ointment: Apply over-the-counter options like Active Skin Repair or prescription mupirocin as directed.
Hygiene measures: Wash the area gently with soap and water before applying ointment.
Cut your child’s nails short: This helps prevent scratching and spreading the infection.
Keep the area covered: Use a light bandage to reduce transmission risk if it’s in a location where that is possible.
If your child has multiple lesions:
Consult your pediatrician: Oral antibiotics may be necessary to control the infection effectively.
Treatment for Impetigo
Topical antibiotics: For mild, localized infections, mupirocin ointment can be effective.
Oral antibiotics: When the infection is widespread or unresponsive to topical treatment, oral antibiotics like cephalexin may be prescribed.
when to seek help
Contact your pediatrician if:
The lesions are spreading rapidly or worsening despite treatment.
Your child develops fever, chills, or signs of systemic illness.
The skin around the sores becomes red, warm, or tender (possible sign of cellulitis).
Your child has recurrent impetigo infections, which may indicate an underlying issue.
and just remember…
Impetigo can look concerning, but it is usually a mild infection that responds well to treatment. With prompt care, most children recover quickly without complications. Remember, you're not alone in managing your child's health—your pediatrician is here to support you every step of the way.
