Why does impetigo keep coming back?

Impetigo may keep coming back when bacteria are transferred again or irritated skin remains vulnerable. Repeated sores deserve a fresh assessment because the rash may need a different treatment or may be another skin condition.

A new episode can follow scratching, insect bites, cuts, or inflamed skin. Household or close contacts may carry infection without obvious sores, and shared towels or sports equipment can transfer bacteria. Incomplete use of a prescribed treatment can also leave the problem unresolved. An itchy condition such as [Atopic Dermatitis](/conditions/atopic-dermatitis/) may keep breaking the skin, while [Crusting Skin](/symptoms/skin-crusting/) can have causes other than impetigo.

Arrange a clinician review rather than repeatedly using an old prescription. Mention where each episode starts, whether anyone else has sores, and whether eczema, itching, or skin injury is present. Wash hands, keep nails short, avoid picking, and do not share towels, bedding, razors, or clothing. Follow the new plan carefully; it may include [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) or [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/) according to the findings.

Seek prompt medical care when sores return soon after treatment, spread quickly, become painful or swollen, or are accompanied by fever. Get urgent advice if the face or area around an eye is involved, or if the person seems unusually unwell. A recurring rash that does not look like previous impetigo also needs examination.

Ask whether the diagnosis should be checked, whether a skin sample or contact review is useful, and whether an underlying itchy rash is contributing. Ask how to clean household items and how to recognise an early recurrence.
