'''Plague''' is a deadly [http://en.wikipedia.org/wiki/Infectious_disease infectious disease] that is caused by the enterobacteria [http://en.wikipedia.org/wiki/Yersinia_pestis Yersinia pestis], named after the French-Swiss bacteriologist [http://en.wikipedia.org/wiki/Alexandre_Yersin Alexandre Yersin]. Primarily carried by rodents (most notably rats) and spread to [[humans]] via fleas, the disease is notorious throughout [[history]], due to the unrivaled [[scale]] of [[death]] and devastation it brought. Until June 2007, plague was one of only three [[diseases]] specifically reportable to the [http://en.wikipedia.org/wiki/World_Health_Organization World Health Organization] (the two other ones were [http://en.wikipedia.org/wiki/Cholera cholera] and [http://en.wikipedia.org/wiki/Yellow_Fever yellow fever]). Depending on lung infection, or [[sanitary]] conditions, plague also can be spread in the [[air]], by direct contact, or by [[contaminated]] undercooked [[food]] or materials. The [[symptoms]] of plague depend on the [[concentrated]] areas of infection in each [[person]]: such as [http://en.wikipedia.org/wiki/Bubonic_plague bubonic plague] in lymph nodes, [http://en.wikipedia.org/wiki/Septicemic_plague septicemic plague] in blood vessels, [http://en.wikipedia.org/wiki/Pneumonic_plague pneumonic plague] in lungs, and so on. Medicines can cure plague if detected early. Plague is still endemic in some parts of the world.[http://en.wikipedia.org/wiki/Plague_%28disease%29#Second_Pandemic:_Black_Death]
