What type of infection is impetigo?

Impetigo is classified as a contagious skin infection, primarily caused by bacterial organisms, specifically Staphylococcus aureus or Streptococcus pyogenes. This condition commonly affects children and can spread through close contact between individuals or from contaminated objects. The infection typically presents as red sores or blisters that can ooze, crust over, and appear honey-colored.

The other types of infections listed, such as respiratory infections, viral infections, and fungal infections, are not representative of impetigo’s characteristics. Respiratory infections affect the respiratory system, while viral infections are caused by viruses and exhibit distinct symptoms and transmission methods. Fungal infections, on the other hand, involve fungi and typically manifest in different forms, such as ringworm or athlete's foot. Understanding that impetigo is a skin condition linked to bacteria helps clarify its infectious nature and the importance of hygiene and proper treatment to prevent its spread.
