impetigo
Pronunciation: im-puh-TY-go
Superficial bacterial skin infection characterized by honey-crusted lesions, most commonly caused by Staphylococcus aureus in children.
Full Definition
A superficial bacterial infection of the skin that primarily affects children, characterized by vesicles that rupture and form characteristic honey-colored crusts. Two main forms exist: non-bullous impetigo (more common, caused by Staphylococcus aureus or group A Streptococcus) and bullous impetigo (caused by specific strains of S. aureus that produce exfoliative toxin). The condition is highly contagious and spreads through direct contact or fomites. Diagnosis is typically clinical, though bacterial culture may be performed if MRSA is suspected. Treatment involves topical or systemic antibiotics depending on extent and severity. Editorial attention should focus on proper classification and causative organism accuracy.
Usage
Usage note: Specify bullous vs. non-bullous type when clinically relevant.
