So called because buboes, or enlarged, inflamed lymph nodes appear in the groin or armpit or on the neck.
Bubonic plague is passed from person to person by the bite of fleas that live on rats.
In bubonic plague, the first symptoms are headache, nausea, vomiting, aching joints, and a high temperature. The lymph nodes of the groin or, less commonly, of the armpit or neck, suddenly become painful and swollen. The buboes swell until they are the size of a chicken egg . In non-fatal cases, the temperature begins to fall in about five days, and approaches normal in about two weeks. In fatal cases, death results in about four days.
