Bubonic plague (yersinia pestis) is generally thought of as a historical disease however, it is still responsible for around 1000-3000 deaths each year worldwide this paper expands the analysis of a model for bubonic plague that encompasses the disease dynamics in rat, flea and human populations. Bubonic plague is an infection of the lymphatic system, usually resulting from the bite of an infected flea, xenopsylla cheopis (the rat flea) in very rare circumstances, as in the septicemic plague, the disease can be transmitted by direct contact with infected tissue or exposure to the cough of another human. The disease was a true mystery for medieval people, whereas the medicine was under-developed to cope with such a disease as the black death, which was presumably a plague the development and spread of the disease was fast and provoked the depopulation of europe.
A model of bubonic plague has previously been proposed to describe the long-term dynamics of this disease [37,38] we adapted this model to the study of outbreaks of the disease on a short time scale, and simplified it so that fleas are not explicitly represented. Bubonic plague n a contagious, often fatal epidemic disease caused by the bacterium yersinia pestis, transmitted from person to person or by the bite of fleas from an infected host, especially a rat, and characterized by chills, fever, vomiting, diarrhea, and the formation of buboes. At least for the black death, such an assertion flies in the face of this disease's speed and distribution, as shown by george christakos, ricardo a olea, marc l serre, hwa-lung yu, and lin-lin wang, interdisciplinary public health reasoning and epidemic modelling: the case of black death, berlin, springer, 2005 see discussion below.

Bubonic plague research papers are historical investigations into this historically devastating diseases study the medical aspects or look in-depth into the historical facts regarding the bubonic plague, otherwise known as the black death. Bubonic plague is the most common form of disease and arises following a bite from a flea that has previously fed on an infected animal (poland and barnes, 1979) the bacteria are disseminated from the initial site of infection to the draining lymph nodes, which become swollen and tender, forming a bubo. Bubonic plague has emerged and spread rapidly across towns, cities, and rural areas in several worldwide epidemics through the whole of history probably the earliest mention of bubonic plague is the old testament record in the first book of samuel giving an account of swellings and rodents that made attack on the philistines (ackroyd 55-57.

Analysis of wills registered in the medieval city of london has shown that 60 percent of londoners were wiped out by the black death from the autumn of 1348 to spring of 1349.
Analysis of 3,800-year-old yersinia pestis genomes suggests bronze age origin for bubonic plague nature communications double burial of the two plague victims in the samara region, russia. The black death, which swept through europe, the near east, and north africa in the mid-14th century, was probably the greatest public health disaster in recorded history and one of the most dramatic examples ever of emerging or reemerging disease.

Bubonic plague, one of three clinical forms of plague, an infectious disease caused by the bacterium yersinia pestisbubonic plague is the most commonly occurring type of plague and is characterized by the appearance of buboes—swollen, tender lymph nodes, typically found in the armpits and groin. Bubonic plague bubonic plague is a disease that is typically passed from rodents to other animals and humans via the bite of a flea the flea acquires the bacterium that causes the disease as it lives.

The black death was an epidemic of bubonic plague, a disease caused by the bacterium yersinia pestis that circulates among wild rodents where they live in great numbers and density such an area is called a 'plague focus' or a 'plague reservoir.
