Causes of impetigo

Causes of impetigo

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 The bacteria can be spread easily through close contact with someone who has the infection, such as through direct physical contact, or by sharing towels or flannels. As the condition doesn't cause any symptoms until four to 10 days after initial exposure to the bacteria, it's often easily spread to others unintentionally. Children and people with diabetes or a weakened immune system – either due to a condition such as HIV or a treatment such as chemotherapy – are most at risk of developing impetigo.
