Final answer:
For a few lesions of impetigo, Mupirocin is the recommended topical therapy. It is highly effective for treating localized impetigo caused by common bacteria like S. aureus and S. pyogenes.
Step-by-step explanation:
The recommended topical therapy for impetigo with a few lesions is Mupirocin. Impetigo is a highly contagious skin infection that can be caused by Staphylococcus aureus (S. aureus), Streptococcus pyogenes (S. pyogenes), or a combination of both, and typically presents as vesicles, pustules, or bullae around the nose and mouth that later rupture to form encrusted sores. The condition requires effective treatment with antibiotics to prevent complications such as acute glomerulonephritis, and for localized infections with a few lesions, a topical antibiotic such as Mupirocin is generally preferred. While systemic antibiotic therapy might be necessary for more extensive cases of impetigo, for limited cases, Mupirocin is typically sufficient to resolve the infection.
