Impetigo

Impetigo is a common bacterial skin infection.  Although it can occur anywhere, it is most common on the face, arms and legs.  It often develops in areas where there has been an injury such as an insect bite, a cut, or other trauma.  It is most common in children under 2 years of age, but may be seen in children of all ages as well as in adults.

Impetigo usually starts as a red area of skin that rapidly increases in size, may form a blister or pustule or ooze, then quickly crusts over.  There may be mild associated pain or pruritus.

Impetigo is highly contagious, and is easily spread by contact with an infected person or by contact with items that an infected person has been touching or playing with.
