Diagnosis of Impetigo
The look of the rash usually gives the diagnosis away. Small red spots appear, which often join up and then blister. When the blisters burst, a yellow fluid seeps out, forming a crust over the area. The spots may be itchy or sore.
Sometimes cold sores caused by the herpes simplex virus can look very similar. In the occasional confusing case, a swab for laboratory analysis will help to be certain.
