L01.0: Impetigo [any organism] [any site]

Your skin has been inflamed by bacteria.

Your skin has turned red in some places. Pointed nodules or blisters have formed in these areas. The blisters are sometimes pus-filled. When the blisters burst, yellow crusts often form. This often affects the face and hands. Hair roots can also become inflamed.

This superficial skin inflammation is caused by bacteria and can be highly infectious. Therefore, one should avoid contact with other people and any objects that are frequently used. The inflammation usually starts via small flesh wounds, and it is helped by scratching or a weak immune system.
