Impetigo is best described as what type of condition?

Impetigo is best described as a bacterial skin infection primarily caused by Staphylococcus aureus or Streptococcus pyogenes. It typically presents as red sores or blisters that can burst and form a honey-colored crust. This condition is highly contagious and commonly seen in children, often spreading through direct contact or by sharing items like towels or toys.

Understanding that impetigo is caused by bacteria clarifies why it is categorized as a bacterial skin infection rather than a viral one, which would involve pathogens like herpes simplex virus, or a fungal infection that would be attributed to organisms such as Candida or dermatophytes. Additionally, an allergic skin reaction refers to conditions resulting from hypersensitivity or contact with allergens, which is distinct from the infectious etiology of impetigo. Therefore, recognizing impetigo as a bacterial skin infection is crucial for proper diagnosis and treatment.
