A preschool child has honey-crusted lesions around the nose and mouth with satellite lesions and other children in day care have similar lesions. How will this be treated?

• A. Bacitracin cream applied to lesions for 10-14 days
• B. Amoxicillin-clavulanate 90 mg/kg/day for 10 days
• C. Mupirocin ointment applied to lesions until clear
• D. Amoxicillin 40-50 mg/kg/day for 7 to 10 days

Answer: (B)

This scenario tests recognizing when impetigo requires systemic therapy due to spread and contagion in a daycare setting. When honey-colored crusts appear around the nose and mouth and there are satellite lesions with several children affected, topical treatments are often insufficient because the infection is widespread and easily transmitted. Impetigo is usually caused by Staphylococcus aureus or Streptococcus pyogenes. For limited disease, topical antibiotics such as mupirocin or bacitracin can be effective. However, with multiple lesions and an outbreak in a daycare, systemic therapy is preferred to eradicate the bacteria more quickly and reduce transmission. Amoxicillin-clavulanate is chosen because it covers both Staph aureus (including beta-lactamase–producing strains) and Streptococcus, providing reliable coverage in a mixed infection scenario. The typical pediatric dosing is around 90 mg/kg per day of the amoxicillin component, divided into two doses, for about 7–10 days (commonly 10 days in practice). So, systemic amoxicillin-clavulanate is the best choice here to effectively treat the outbreak and contain spread, whereas topical therapy alone would likely be inadequate in this setting.
