Impetigo is a highly contagious skin infection that primarily affects infants and children. Impetigo usually appears as red sores on the face, especially around a child's nose and mouth. Although it commonly occurs when bacteria enter the skin through cuts or insect bites, it can also develop in perfectly healthy skin.


Symptoms may include:


  • red sores that quickly rupture, ooze and then form a yellowish-brown crust
  • itching
  • painless, fluid-filled blisters
  • in the more serious form, painful fluid- or pus-filled sores that turn into deep ulcers

Causes may include:


  • bacteria
    • staphylococcus aureus (staph)
    • streptococcus pyogenes (strep)
  • injury to the skin (from a condition like dermatitis)
  • infections caused by cut, scraps or insect bites
  • exposure to sores of someone who is infected

Treatment may include:


  • proper hygiene
  • medication
