Impetigo is very contagious and is spread by touch from one person to another. A person with impetigo can also spread the infection from one spot on the body to another by touching themselves. Personal hygiene does not affect a person's likelihood of developing impetigo, nor should impetigo be viewed as an indication of poor hygiene.
Antibiotic ointment is applied lightly over the lesions.
Occasionally, oral antibiotics are prescribed.
