What Is Impetigo?
5. Causes
Impetigo is usually caused by Streptococcus pyogenes or Staphylococcus aureus bacteria. These bacteria are able to cause the infection when the skin is broken, allowing the bacteria to enter. When it is contracted in this manner, it is known as primary impetigo.
It can also sometimes be caused by other skin conditions like eczema, which is known as secondary impetigo.
Regardless, the patient will show no symptoms for the first 10 days or so, meaning it is more likely to be spread to other people. People can become exposed to the bacteria through direct skin contact with other people, or by contact with contaminated items, such as towels and toys.
