==Signs and symptoms==

===Contagious impetigo===
This most common form of impetigo, also called nonbullous impetigo, most often begins as a red sore near the nose or mouth which soon breaks, leaking [[pus]] or fluid, and forms a honey-colored [[wound healing|scab]],<ref name=Cole>{{cite journal | vauthors = Cole C, Gazewood J | title = Diagnosis and treatment of impetigo | journal = American Family Physician | volume = 75 | issue = 6 | pages = 859–864 | date = March 2007 | pmid = 17390597 | url = http://www.aafp.org/afp/2007/0315/p859.html | url-status = live | archive-url = https://web.archive.org/web/20150430100234/http://www.aafp.org/afp/2007/0315/p859.html | archive-date = 2015-04-30 }}</ref> followed by a red mark which often heals without leaving a scar. Sores are not painful, but they may be itchy. [[Lymph node]]s in the affected area may be swollen, but fever is rare. Touching or scratching the sores may easily spread the infection to other parts of the body.<ref name=Mayo>{{cite web|url= http://semj.sums.ac.ir/vol8/jul2007/impetigo.htm|title= Impetigo|author= Mayo Clinic staff|date= 5 October 2010|work= Mayo Clinic Health Information|publisher= Mayo Clinic|access-date= 25 August 2012|url-status= dead|archive-url= https://web.archive.org/web/20121128081224/http://semj.sums.ac.ir/vol8/jul2007/impetigo.htm|archive-date= 28 November 2012}}</ref>

[[Bullous impetigo]], mainly seen in children younger than two years, involves painless, fluid-filled [[blister]]s, mostly on the arms, legs, and trunk, surrounded by red and itchy (but not sore) skin. The blisters may be large or small. After they break, they form yellow scabs.<ref name=Mayo/>

===Ecthyma===
[[Ecthyma]], the nonbullous form of impetigo, produces painful fluid- or pus-filled sores with redness of skin, usually on the arms and legs, become [[ulcer (dermatology)|ulcers]] that penetrate deeper into the [[dermis]]. After they break open, they form hard, thick, gray-yellow scabs, which sometimes leave scars. Ecthyma may be accompanied by swollen [[lymph node]]s in the affected area.<ref name= Mayo/>
