The main visual characteristics of impetigo include isolated pustules that crust and rupture. This skin infection, typically caused by staphylococci or streptococci bacteria, presents itself prominently with these features. The initial presentation often begins as red sores or blisters that break open, ooze fluid, and then form a characteristic yellowish-brown crust. This crusting is a hallmark sign of impetigo and helps distinguish it from other skin conditions. The formation of pustules is particularly significant, as these can become filled with pus and lead to the crusting that defines the appearance of impetigo. Understanding these characteristics is crucial for accurate identification and subsequent treatment of the condition.
