Signs and Symptoms
There are 2 common forms of impetigo: impetigo with blisters and impetigo without blisters (fluid-filled bubbles on the skin surface).

Non-blistering impetigo:
  • Tiny pimples or red areas quickly turn into oozing, honey-colored, crusted patches (usually less than an inch) that spread.
  • The face or injured (traumatized) areas of the skin are affected.
  • There may be some itching or swollen lymph nodes, but the child feels generally well.
  • Sometimes deeper, pus-filled sores and scabs that leave scars occur.
Blistering impetigo:
  • Painless blisters (about an inch or less) occur that may break easily.
  • These often spread to the face, trunk, arms, or legs.
  • The person feels generally well.
The infection associated with impetigo may be:
  • Mild – Only a few of either type of lesion over a small area of skin, and the child feels well otherwise.
  • Moderate – Over 10 lesions, and several small skin areas are affected.
  • Severe – Many lesions; large areas of skin are affected; and/or the child feels ill, with fever, diarrhea, or weakness.
