What is the primary cause of impetigo?

Impetigo is primarily caused by a bacterial infection, specifically by Staphylococcus aureus or Streptococcus pyogenes. These bacteria are known for their ability to invade the skin, particularly in areas where the skin may be compromised, such as abrasions or insect bites. Impetigo is highly contagious and can easily spread to others through direct contact or by touching contaminated surfaces.

Understanding that impetigo is a bacterial condition is crucial for effective treatment and prevention. Common symptoms include red sores, blisters, and honey-colored crusts that often develop around the nose and mouth. Treatment typically involves antibiotic ointments or oral antibiotics to eliminate the bacterial infection. This knowledge helps ensure proper diagnosis and therapeutic approaches for patients affected by this skin disorder.
