Impetigo is a skin infection caused by staphylococcal or streptococcal bacteria.
All ages can get impetigo, but it spreads more easily in preschool or elementary students.
Impetigo begins as a cluster of small blisters. As the infection spreads, the blisters become yellow, crusty, and weepy as pus drains from the impetigo. The infection is easily spread, and can appear on other parts of the bode i.e. the hands or arms, along with spreading to other areas of the face. Impetigo is most often found around the nose and mouth. Impetigo spreads easily, especially in small children.
