What are possible complications of impetigo?

One potentially serious, but rare, complication of impetigo caused by strep bacteria is glomerulonephritis, a condition producing kidney inflammation. Many specialists are not convinced that treating impetigo will prevent glomerulonephritis from occurring.

Will impetigo leave scars?

Because the crusts and blisters of impetigo are superficial, impetigo generally does not leave scars. Affected skin looks red for a while after the crusts go away, but this redness fades in a matter of days to weeks.

Can impetigo be prevented?

Routine hand washing with soap and warm water is an important and effective mechanism to prevent the spread of impetigo.
