Impetigo infection on the cheek of a 45-year-old woman. Impetigo is a highly contagious skin infection caused by Staphylococcus bacteria. The condition starts as a red patch and develops into small pustules that merge to form a yellow, crusty sore. Patients must not share items like towels that touch the affected area, as this will spread the disease. Antibiotic drugs should heal the infection in about five days.
