Public Health Fact Sheet
What is Impetigo?
Impetigo is a contagious skin infection caused by Streptococcus (Strep) or Staphylococcus (Staph) bacteria. The infection occurs when the bacteria get into cuts, scrapes or insect bites.
How is Impetigo spread?
Impetigo is spread from person to person through direct contact with the discharge from the sores; for example, when someone touches an impetigo rash and then touches another person. Less commonly, it can be spread through touching articles (such as clothing, bedding, and towels) contaminated with the discharge from the sores.
How is it treated?
The infection is treated with antibiotics which may be applied to the skin in the form of an ointment, or medication taken by mouth.
How can I prevent Impetigo?
Wash all cuts, scrapes, and other lesions thoroughly with soap and water to prevent infection from occurring. Exclude students with impetigo from school or day care until 24 hours after the start of treatment.
