Impetigo

  • Introduction 

    Impetigo is a common and highly contagious skin infection that causes sores and blisters. It’s not usually serious and often improves within a week of treatment.

    There are two types of impetigo:

    • non-bullous impetigo, which typically affects the skin around the nose and mouth, causing sores to develop that quickly burst to leave a yellow-brown crust
    • bullous impetigo, which typically affects the trunk (the central part of the body between the waist and neck), causing fluid-filled blisters (bullae) to develop that burst after a few days to leave a yellow crust

    Both types of impetigo may leave behind some red marks when the crusts have cleared up, but these will usually improve over the following days or weeks.
