Impetigo is a bacterial infection that involves the superficial skin.[2] The most common presentation is yellowish crusts on the face, arms, or legs.[2] Less commonly there may be large blisters which affect the groin or armpits.[2] The lesions may be painful or itchy.[3] Fever is uncommon.[3]

It is typically due to either Staphylococcus aureus or Streptococcus pyogenes.[3] Risk factors include attending day care, crowding, poor nutrition, diabetes mellitus, contact sports, and breaks in the skin such as from mosquito bites, eczema, scabies, or herpes.[3][4] With contact it can spread around or between people.[3] Diagnosis is typically based on the symptoms and appearance.[3]

Prevention is by hand washing, avoiding people who are infected, and cleaning injuries.[3] Treatment is typically with antibiotic creams such as mupirocin or fluidic acid.[3][5] Antibiotics by mouth, such as cephalexin, may be used if large areas are affected.[3] Antibiotic-resistant forms have been found.[3]

Impetigo affected about 140 million people (2% of the world population) in 2010.[6] It can occur at any age, but is most common in young children.[3] In some places the condition is also known as "school sores".[1] Without treatment people typically get better within three weeks.[3] Recurring infections can occur due to colonization of the nose by the bacteria.[7][8] Complications may include cellulitis or poststreptococcal glomerulonephritis.[3] The name is from the Latin impetere meaning "attack".[9]
