| ==Overview==
| |
| | |
| The pathognomic sign of plague is a very painful, usually [[swollen]], and often hot-to-the touch [[lymph node]], called a [[bubo]]. This finding, accompanied with [[fever]], extreme [[exhaustion]], and a history of possible exposure to rodents, rodent fleas, wild rabbits, or sick or dead [[carnivores]] should lead to suspicion of plague.
| |
| | |
| Onset of bubonic plague is usually 2 to 6 days after a person is exposed. Initial manifestations include [[fever]], [[headache]], and general [[illness]], followed by the development of painful, swollen regional lymph nodes. Occasionally, buboes cannot be detected for a day or so after the onset of other symptoms. The disease progresses rapidly and the [[bacteria]] can invade the [[bloodstream]], producing severe illness, called [[plague septicemia]].
| |
| | |
| Once a [[human]] is [[infected]], a progressive and potentially [[fatal]] illness generally results unless specific [[antibiotic]] therapy is given. Progression leads to [[blood infection]] and, finally, to [[lung]] infection. The infection of the lung is termed [[plague pneumonia]], and it can be transmitted to others through the expulsion of infective respiratory droplets by [[coughing]].
| |
| | |
| The incubation period of primary pneumonic plague is 1 to 3 days and is characterized by development of an overwhelming [[pneumonia]] with high fever, cough, bloody [[sputum]], and [[chills]]. For plague pneumonia patients, the [[death]] rate is over 50%.
