An analysis of the bubonic plague disease

The evidence of the plague is found in the broad swath it cut across North Africa, Asia, and Europe, its terrifying symptoms, and its impact on society.

History of the Disease Ancient history includes vivid descriptions of epidemics that seized their victims suddenly and produced an agonizing death. One such episode occurred in Athens, Greece, in B.

Some historians believe these lethal outbreaks were caused by the same disease responsible for the Black Death—the bubonic plague. Other historians, though, note some differences between the symptoms observed in the ancient episodes and those reported during the fourteenth century.

The growth of international trade and military invasions later provided the opportunity for diseases to spread rapidly from one population to another.

Smallpox and measles came first, both causing high mortality within populations that had not previously been exposed. Bubonic plague arrived in force in the sixth century C.

The powerful and still expanding Byzantine empire, centered in Constantinople now Istanbul, Turkeywas so devastated that its political and military power sharply declined. The plague did not entirely disappear but entered a long phase of withdrawal with occasional local outbreaks, especially in central Asia.

When it did return it was with a furious rush that created widespread panic in populations already beset with both natural and human-made disasters. The fourteenth century suffered an entire catalog of catastrophes, including earthquakes, fires, floods, freezing weather, nauseating mists, and crop failures—all of which did not even seem to slow down the incessant warfare and banditry.

Social order was weakened under the stress, and a hungry and exhausted population became more vulnerable to influenza and other opportunistic diseases.

It was within this already precarious situation that the plague once again crossed into Europe. There had been rumors about a deadly new epidemic sweeping through the Middle East, probably starting in The plague had taken hold among the Tartars of Asia Minor. Somebody had to be blamed—in this case, the Christian minority.

Later, as the plague devastated Europe, Jews were not only blamed but burned alive. The besieging army soon was ravaged by the plague and decided to leave. As a parting shot, the Tartars used catapults to hurl plague-infected corpses over the city walls. Some residents died almost immediately; the others dashed for their galleys a type of oar-propelled ship and fled, taking the disease with them.

Sicily and then the rest of Italy were the earliest European victims of the plague. It would spread through almost all of Europe, wiping out entire villages and decimating towns and cities. It is estimated that a third of the European population perished during the Black Death.

The death toll may have been as high or even higher in Asia and North Africa, though less information is available about these regions. The world was quickly divided between the dead and their frequently exhausted and destitute mourners.

Yersinia pestis infects rodents, producing blood poisoning. Fleas that feed on the dying rodents carry the highly toxic bacteria to the next victim—perhaps a human. Among the first symptoms in humans were swollen and painful lymph glands of the armpit, neck, and groin.Bubonic Plague words, approx.

3 pages 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 plague is a serious bacterial infection that can be deadly. Sometimes referred to as the “black plague,” the disease is caused by a . At that time, bubonic plague was a much feared disease but its cause was not understood. The credulous blamed emanations from the earth, "pestilential effluviums", unusual weather, sickness in livestock, abnormal behaviour of animals or an increase in the numbers of moles, frogs, mice or flies.

It was not until that the identification . 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 Yersinia pestis spread by fleas.

Introduction Bubonic Plague is brought by the Yersinia pestis, which is a Gam-negative, bipolar-staining coccobacilli. As learned in classes, the coccobacilli are rod or oval in shape, and normally short in size. Beginning in and continuing for a full five years, a devastating plague swept Europe, leaving in its wake more than twenty million people dead.

This epidemic now known as the "Black Death" was an outbreak of bubonic plague which had begun somewhere in the heart of Asia and spread westward along.
