DISEASE OF THE DAY:  Impetigo

Impetigo is a common superficial bacterial infection of the skin. It is highly contagious and is frequently seen in otherwise healthy children as well as occasionally in adults in poor health. Two forms exist, classically referred to as impetigo contagiosa and impetigo bullosa; they differ from each other simply by the size of the pustules. In the past, impetigo contagiosa was almost exclusively caused by a group A beta-heolytic streptococci and impetigo bullosa by Staphylococcus aureus, all cases of impetigo nowadays tend to be caused by the latter.
