### What is Impetigo? Impetigo is a common skin infection that primarily affects children but can occur in adults as well. It is highly contagious and can spread through direct contact with an infected person or by touching contaminated surfaces like towels. ### Signs and Symptoms - **Initial Stage**: Impetigo starts as a small cluster of blisters. These blisters quickly break open, leaving a red, moist area that oozes or weeps fluid. - **Crusting Stage**: Within a few days, the affected area develops a golden or dark-yellow crust that looks like grains of brown sugar. - **Location**: Impetigo usually appears on the face but can also develop on exposed areas of the arms and legs. - **Spread**: The infection may spread at the edges of the infected area or to other parts of the skin. ### When to See a Doctor - If you have sores or a rash that worsens or becomes more uncomfortable, seek medical attention promptly. - If small, pus-filled sores with a dark brown crust form, it may indicate ecthyma, a deeper skin infection that can cause scarring and permanent changes in skin pigmentation if left untreated. ### Important Note Impetigo sores may be mistaken for herpes, a viral infection. However, impetigo spreads faster and never develops inside the mouth. If you are unsure, consult a doctor for an accurate diagnosis.
