What demographic is most commonly affected by impetigo?

Impetigo is most commonly seen in children, particularly those between the ages of 2 to 6 years old. This affliction is highly contagious and often spreads in settings where children are in close contact, such as schools and playgrounds. Their immature immune systems and tendencies to engage in activities that can cause skin abrasions or cuts increase their susceptibility to the bacteria that cause impetigo.

Understanding this demographic's vulnerability can help in taking preventive measures, such as promoting good hygiene practices. Additionally, the presence of impetigo is often associated with warm, humid weather and environments where group interactions are frequent, both of which are more prevalent among young children who play together. Therefore, this is the demographic most commonly affected by impetigo.
