Question

What causes impetigo?

Answer 1

Impetigo occurs when the skin becomes infected with bacteria, usually either Staphylococcus aureus or Streptococcus pyogenes.

The bacteria can infect the skin in two main ways:

through a break in otherwise healthy skin – such as a cut, insect bite or other injury – this is known as primary impetigo

through skin damaged by another underlying skin condition, such as head lice, scabies or eczema – this is known as secondary impetigo
