What type of infection is impetigo?

Impetigo is classified as a bacterial infection primarily caused by two types of bacteria: Staphylococcus aureus and Streptococcus pyogenes. It is characterized by the formation of red sores on the face, especially around the nose and mouth, and can spread easily through direct contact. Due to its contagious nature, understanding that impetigo is bacterial is vital for proper diagnosis and treatment. Treatment typically involves the use of topical or oral antibiotics, which target the bacteria causing the infection. This classification is critical for practitioners as it determines the course of intervention needed to alleviate the condition and prevent its spread.
