Bullous impetigo is primarily a staphylococcal disease.
Nonbullous impetigo was once thought to be primarily a streptococcal disease, but staphylococci are isolated from the majority of lesions in both bullous and nonbullous impetigo. S. aureus is now known to be the primary pathogen in both bullous and nonbullous impetigo. Children in close physical contact with each other have a higher rate of infection than do adults. Impetigo may occur after a minor skin injury such as an insect bite, but it most frequently develops on apparently unimpaired skin impetigo, infantigo, infintigo. The disease is self-limiting, but when untreated it may last for weeks or months.
