Impetigo 脓疱病 (Reading & Sharing)

The skin is normally populated with bacteria, and under healthy normal circumstances these bacteria do not routinely lead to infection.

Ferri (2018) defines impetigo as a common bacterial superficial skin infection that is generally caused by streptococcal or staphylococcal bacteria. Skin lesions can be described a bullous when multiple vesicles form on the skin, enlarge, and weep a yellow honey-like crust due to a toxin produced at the site of the infection (Ferri, 2018). As the weeping lesions become contagious and spread to the others, a dry scaly boarder forms to replace the old fluid-filled vesicle (Ferri, 2018).  Non-bullous impetigo begins as a single red papule, usually around the nose or mouth, weep and produce a honey-like crust (Ferri, 2018).
