Impetigo is characterized by starting as a single lesion that can spread to other areas of the skin and often crusts over. This highly contagious bacterial infection typically presents as red sores, which may form blisters and eventually develop a characteristic honey-colored crust as it heals. The initial lesion can appear on the face, particularly around the nose and mouth, as well as on hands and other areas. The possibility of spreading through direct contact or via shared items underscores the importance of hygiene and prompt treatment to manage the condition effectively.

In contrasting the characteristics of Impetigo with the other options, it is clear that choices describing a chronic skin condition, a form of eczema, and a viral infection affecting the respiratory system do not align with the typical presentation or etiology of Impetigo. Hence, the correct choice accurately reflects the nature of this infectious skin condition.
