Bacterial Invaders

The main bacteria responsible for impetigo are Staphylococcus aureus and Streptococcus pyogenes. These bacteria can enter the skin through cuts, bites, or other minor injuries. Once inside, they multiply quickly, leading to the characteristic sores and blisters of impetigo.

Environmental Factors

Impetigo thrives in warm and humid environments, which provide ideal conditions for bacteria to grow. Crowded living conditions and poor hygiene practices further facilitate the spread of the infection, making it more common in certain settings.
Impetigo is a contagious bacterial skin infection primarily caused by Staphylococcus aureus and Streptococcus pyogenes. It is characterized by sores and blisters.

The Role of Carriers

Carriers of group A Streptococcus or Staphylococcus aureus can spread the bacteria even if they're not showing symptoms. This can lead to impetigo outbreaks, especially in close-knit communities or groups of children. Identifying and treating carriers is crucial in controlling the spread.
