https://themedicalxchange.com/wp-content/uploads/2019/12/2511_5_Most_Common_Skin_Diseases_Chap_4_Fig1.png960720Impetigo is a common bacterial infection of the superficial skin that most commonly occurs among children. Cases in adolescents and adults are commonly observed with some type of skin lesions, such as an abrasion or dermatitis. Non-bullous impetigo, or impetigo contagiosa, is the more common of the two types and is characterized by yellowish crusty lesions. In children, these often include perioral involvement but can appear anywhere on the skin. Bullous impetigo, as the name suggests, is characterized by large, flaccid bullae that are prone to rupture and ooze yellow fluid. These develop most commonly on the trunk, the extremities, or in intertriginous areas, such as the axilla or buttocks. Impetigo is extremely common in young children, with an average estimated global prevalence of 12.3%. Generally, the prevalence is higher in tropical and low-income areas of the world than in areas with temperate climates, but prevalence rates near 20% have been reported among underprivileged children living in high-income countries, including Canada. Although impetigo readily resolves without scarring even in the absence of treatment, topical antibiotics can speed healing and reduce risk of transmission. In general, systemic involvement and complications are rare, but impetigo caused by methicillin-resistant Staphylococcus aureus (MRSA) is potentially serious without prompt intervention.
