Summary Introduction

Introduction:

Impetigo is also known as pyoderma (pyon means pus and derma means skin), which is caused by Streptococcus pyogenes. It is a contagious disease which is characterized by the development of flattened, small, red patches on the skin and limbs. These patches contain pus filled, oozing vesicles on a red base. On the broken down of these vesicles, thick honey colored sticky liquid ooze out that firmly attached to the skin and cause intense itching.
