Impetigo in Children: What It Means

It commonly affects exposed skin such as the face, arms, or legs, but it can occur anywhere bacteria enter irritated or broken skin. A child may have itchy patches that become wet, crusted, or sore. Scratching can carry infection to nearby skin, while hands, towels, bedding, toys, and close contact can pass bacteria between people. Several childhood rashes resemble impetigo, so appearance alone may not settle the diagnosis.

A clinician can check whether the child needs a skin treatment or medicine by mouth, especially when there are many lesions or the infection is spreading.

Wash the affected skin gently, pat it dry, and keep sores covered if the child can tolerate a clean dressing. Keep fingernails short and encourage handwashing after touching the area. Do not share towels, clothing, bedding, cups, or personal items. Wash used fabrics regularly and avoid squeezing blisters or removing crusts by force. Give prescribed treatment for the full instructions provided, even if the skin begins to look calmer. A clinician can advise when the child may return to nursery, school, swimming, or sports.

Contact a clinician promptly if sores are spreading, painful, swollen, or increasingly red, or if the child develops fever, unusual tiredness, poor drinking, or reduced urination. Seek urgent help for rapidly worsening skin, severe swelling, marked pain, or a child who appears seriously unwell. Sores close to the eyes deserve prompt assessment.

Ask what features support impetigo, how to apply or give the treatment, how to clean the child’s hands and belongings, whether siblings need checking, and what changes should prompt a same-day review.
