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.
