Impetigo infection on the forehead of a 35-year-old man. Impetigo is a highly contagious bacterial skin infection caused by Staphylococcus bacteria. One form of the infection is common in babies and children. Another form (bullous impetigo) is less contagious and occurs at any age. The infection starts as a red patch and develops into small pustules that join together, forming a yellow, crusty sore. Patients must not share any items that come into contact with the affected area, such as towels, as this will spread the infection. Impetigo is treated locally with antibiotic drugs. The infection heals within seven to ten days.
