Nonbullous Impetigo is a contagious superficial infection of the skin due to streptococci, staphylococci or both. It is characterized by superficial vesicular lesions that later become pustular and then crusted, the resultant crusts being often honey-coloured. Lesions predominantly occur on the face, arms and legs of infants and children.
Impetigo can present as folliculitis, which is considered to be impetigo of the hair follicles caused by Staphylococcus aureus.
