What type of infection is impetigo classified as?

Impetigo is classified as a bacterial infection. It is caused primarily by two types of bacteria: Staphylococcus aureus and Streptococcus pyogenes. This skin infection is highly contagious and often appears in the form of red sores, typically around the nose and mouth, and can also develop on other parts of the body.

Understanding the nature of impetigo is vital in the healthcare field, especially for those working in primary care. Due to its bacterial origin, impetigo can be effectively treated with appropriate antibiotic therapy, which is important in preventing its spread, particularly in communal settings like schools and daycare centers. Missed identification of the infection type could lead to improper treatment; for instance, using antifungal treatments would be ineffective if the infection is indeed bacterial. This highlights the importance of recognizing the specific characteristics and causative agents of skin infections.
