Signs and symptoms. Contagious impetigo. This most common form of impetigo, also called nonbullous impetigo, most often begins as a red sore near the nose or mouth which soon breaks, leaking pus or fluid, and forms a honey-colored scab, followed by a red mark which heals without leaving a scar.
Impetigo is caused by the staphylococcus aureus, or more rarely streptococcus pyogenes bacteria. Although the sores are not painful, they may itch a great deal. It is important not to touch or scratch them so that the infection does not spread to other parts of the body and other people.
