what years did the bubonic plague occur

Bubonic plague

Apr 17, †Ј One of the worst plagues in history arrived at Europe's shores in Five years later, some 25 to 50 million people were dead. Nearly years after the Author: John Seven. Jul 05, †Ј The Black Death was a devastating global epidemic of bubonic plague that struck Europe and Asia in the mids. The plague arrived in Europe in .

A familiar nursery rhyme that children have recited as a harmless play song for generations ironically refers to one of Europe's most devastating diseases. The bubonic plague, better known as the? The Black Death,? The first recorded case of the plague was in China in B. But the most significant outbreak was in Europe in the mid-fourteenth century.

Over a five-year period from to25 million people died. One-third to one-half of the European population was wiped out! The first symptoms of bubonic plague appeared within days after infection: fever, headache, and a general feeling of weakness, followed by aches in the upper leg and groin, a white tongue, rapid pulse, slurred speech, confusion, and fatigue.

By the third day, a painful swelling of the lymph glands in the neck, armpits, and groin occurred, and these enlarged areas were called? Bleeding under the skin followed, causing purplish blotches. Dark-ringed red spots on the skin from infected fleabites, or? The victim's nervous system collapsed, causing extreme pain and bizarre neurological disorders. This was the inspiration for? Dance of Death?

Fragile nasal capillaries led how to create custom ipsw excessive sneezing. By the fourth day, wild anxiety and terror overtook the sufferer.

Finally, a sense of resignation registered as the skin blackened, giving rise to? The Black Death.? The simplistic words in the famous nursery rhyme capture the essence of plague's horror. God Bless You? The rhyme also describes highly aromatic flowers and herbs, the?

Many corpses were uncharacteristically cremated? Plague infects both people and rodents, with rodents helping to transmit it further within the population. Fleas feeding on infected rodents can transmit the disease to people as well. Once infected, people can infect others by coughing, sneezing, or close talking.

The origin of? The Black Death? During this period, China was an important trading nation, and what years did the bubonic plague occur trade via the Silk Road helped create the world's first pandemic.

Plague-infected rats on merchant ships spread the disease to western Asia and Europe. In the fall ofItalian merchant ships with crewmembers dying of plague docked in Sicily, and within days the disease spread to the city and the surrounding countryside. The disease killed people so quickly that the Italian novelist Giovanni Boccaccio, whose father and stepmother died of plague, wrote that?

By August, the plague had spread as far north as England. The English writer Daniel Defoe, the author of Robinson Crusoewrote graphically about the plague years It is scarce credible what dreadful cases happened in particular families every day.

People in the rage of the distemper, or in the torment of their swellings, which was indeed intolerable, running out of their own government, raving and distracted, and oftentimes laying violent hands upon themselves, throwing themselves out at their windows, shooting themselves, mothers murdering their own children what is sardines in brine their lunacy, some dying of mere grief as a passion, some of mere fright and surprise without any infection at all, others frightened into idiotism and foolish distractions, some into despair and lunacy, others into melancholy madness.?

For five years, the disease would disappear in winter, when fleas were dormant, and resume its killing spree each spring. The impact of the plague was enormous, as governments, trade, and commerce virtually ceased. Faith in religion decreased because many clergy died and prayer failed to prevent sickness and death. Because trade was difficult, the prices of goods were grossly inflated. A decimated work force required higher wages, leading to peasant revolts in England, France, Belgium, and Italy.

The disease receded inbut never really went away. Smaller outbreaks continued for centuries, affecting all of European society, rich and poor. Two hundred years of recurring death immeasurably changed government, the arts, science, and religion.

Plague epidemics ravaged London in,andreducing its population by 10 to 30 percent during those years. The Italian plague of claimed between 35 and 69 percent of the population. The German plagues between and were equally devastating, and inplague reduced the population of Marseille by 40 percent. The bubonic plague is believed to have killed million people during its year reign of terror. Intwo scientists, Alexandre Emile Jean Yersin and Shibasaburo Kitasato, seperately described organisms they found in the swollen lymph nodes, blood, lungs, liver, and spleen of dead plague patients.

To confirm their findings, they used cultures taken from patient specimens to infect a variety of animals. All the animals died within days. The same rod-shaped organisms found in the original specimens were also found in the animal organs. On the island of Formosa, residents considered handling dead rats a risk for developing plague.

These observations led P. Simond in the late s to suspect that fleas might play a role in the transmission of plague. He observed that people contracted plague only if they were in contact with recently dead rats. They were not affected if they touched rats that were dead for more than 24 hours. Simond showed that the rat-flea transmitted the disease.

In a now classic experiment, a healthy rat separated from direct contact with a recently killed plague-infected rat, died of plague after the infected fleas jumped from the first rat to the second.

Unlike smallpox, the plague is still a threat in some parts of the world. Yersinia pestisthe bacterium that causes bubonic plague, is transmitted through rat-tainted fleabites in densely populated cities and in countries with poor hygiene, or in the open country from infected wild rodents. The most common form of human plague is a swollen and painful lymph gland that forms buboes.

Bubonic plague should be suspected when a person develops a swollen gland, fever, chills, headache, and extreme exhaustion, and lives in a region with infected rodents, rabbits, or fleas.

Infection of the lungs causes the pneumonic form of plague, resulting in a severe respiratory illness. This form of the disease can spread rapidly and is more highly fatal. A person usually becomes ill with bubonic plague two to six days after being infected. When left untreated, the plague-causing bacteria invade the bloodstream and kill 50 to 90 percent of people who get it. Antibiotic therapy effectively treats bubonic plague.

Pneumonic plague is more difficult to treat, and even with antibiotics, victims can die from it. Pneumonic plague occurs when the infectious bacteria infects the lungs. The first signs of illness in pneumonic plague are fever, headache, weakness, and a cough that produces blood or watery sputum.

The pneumonia progresses over two to four days and, without early treatment, death ensues. Bubonic plague is still prevalent in more than 20 countries. In the What are possessives in grammar States, the last rat-borne epidemic occurred in Los Angeles in Since then sporadic cases have occurred, mostly in western states. Sources of cases today are wild rodents, especially squirrels, prairie dogs, and other burrowing rodents.

Plague is found in parts of Russia and China and regularly occurs in Madagascar. Plague also has been reported in western and northern Africa. There is no plague in Australia, and Europe has not seen a case for more than 50 years. The genome sequence is the entire complement of DNA in the cells of an organism. Mapping the genome sequence of the bug that causes plague was valuable because it helped researchers to learn about its evolution.

The large number of genetic changes in the organism over time explain its ability to succeed as a disease-causer over hundreds of years.

Genome sequences are becoming available for more and more organisms. The human genome has been sequenced as well.

There are many useful pieces of information that will help us fight all kinds of infectious and genetic diseases that come from sequencing of genomes. A team of scientists recently mapped the entire genetic structure or genome sequence of Yersinia pestisthe plague-causing bacterium. The genome displays many irregularities due to genetic exchange with other microorganisms, and many of its genes appear to have been acquired from other bacteria and viruses.

The evidence suggests that plague has undergone large-scale genetic change leading to rapid evolution, which makes it able to adapt to survive in many different environments. Plague vaccines have been used since the late nineteenth century, but their effectiveness is uncertain.

Vaccination reduces the incidence and severity of disease resulting from the bite of infected fleas, but it isn't percent effective. The plague vaccine is licensed for use how to call on google voice for free the United States and is available for adults at high risk?

Severe inflammatory reactions are common, and plague vaccine should not be given to anyone with a known hypersensitivity to beef protein, soya, casein, or phenol. Finally, the vaccination routine is complex and requires frequent boosters to maintain its effectiveness.

May 12, †Ј The Black Death of October to c was one of the worst catastrophes in recorded history Ц a deadly bubonic plague that ravaged communities across Europe, changing forever their social and economic fabric. Apr 25, †Ј The first pandemic wave of plague began to die out in Europe after four years, but pockets of the disease remained, and small isolated outbreaks . The bubonic plague, better known as the?The Black Death,? has existed for thousands of years. The first recorded case of the plague was in China in B.C.E. But the most significant outbreak was in Europe in the mid-fourteenth century. Over a five-year period from to , 25 million people died.

Nearly years after the Black Death swept through Europe, it still haunts the world as the worst-case scenario for an epidemic. Called the Great Mortality as it caused its devastation, this second great pandemic of Bubonic Plague became known as the Black Death in the late 17th Century. Modern genetic analysis suggests that the Bubonic plague was caused by the bacterium Yersinia pestis or Y.

Chief among its symptoms are painfully swollen lymph glands that form pus-filled boils called buboes. Sufferers also face fever, chills, headaches, shortness of breath, hemorrhaging, bloody sputum, vomiting and delirium, and if it goes untreated, a survival rate of 50 percent. During the Black Death, three different forms of the plague manifested across Europe. Below is a timeline of its gruesome assault on humanity.

Fresco by an anonymous painter depicting 'The Triumph of Death. The strain of Y. It is possibly passed to humans by a tarabagan, a type of marmot. The deadliest outbreak is in the Mongol capital of Sarai, which the Mongols carry west to the Black Sea area. Mongol King Janiberg and his army are in the nearby city of Tana when a brawl erupts between Italian merchants and a group of Muslims. Following the death of one of the Muslims, the Italians flee by sea to the Genoese outpost of Caffa and Janiberg follow on land.

As the army catapults the infected bodies of their dead over city walls, the under-siege Genoese become infected also. Both sides in the siege are decimated and survivors in Caffa escape by sea, leaving behind streets covered with corpses being fed on by feral animals. One ship arrives in Constantinople, which, once infected, loses as much as 90 percent of its population.

Another Caffan ship docks in Sicily, the crew barely alive. Here the plague kills half the population and moves to Messina. Fleeing residents then spread it to mainland Italy, where one-third of the population is dead by the following summer.

The plague arrives in France, brought by another of the Caffa ships docking in Marseille. It spreads quickly through the country. A different plague strain enters Europe through Genoa, brought by another Caffan ship that docks there. The Genoans attack the ship and drive it away, but they are still infected.

Italy faces this second strain while already battling the previous one. Venice faces its own outbreak by pioneering the first organized response, with committees ordering ship inspections and burning those with contagions, shutting down taverns, and restricting wine from unknown sources.

The canals fill with gondolas shouting official instructions for disposing of dead bodies. Despite those efforts, the plague kills 60 percent of the Venetian population. The plague awakes an anti-Semitic rage around Europe, causing repeated massacres of Jewish communities, with the first one taking place in Provence, where 40 Jews were murdered. The plague enters England through the port of Melcombe Regis , in Dorset. As it spreads through the town, some escape by fleeing inland, inadvertently spreading it further.

A group of religious zealots known as the Flagellants first begin to appear in Germany. These groups of anywhere from 50 to hooded and half-naked men march, sing and thrash themselves with lashes until swollen and bloody. Originally the practice of 11th-century Italian monks during an epidemic, they spread out through Europe. Also known for their violent anti-Semitism, the Flagellants mysteriously disappear by The plague hits Marseille, Paris and Normandy, and then the strain splits, with one strain moving onto the now-Belgian city of Tournai to the east and the other passing through Calais.

In towns throughout Germany and France, Jewish communities are completely annihilated. Marseilles is also considered a safe haven for Jews. Flagellants, known as the Brothers of the Cross, scourging themselves as they walk through the streets in order to free the world from the Black Death, in the Belgium town of Tournai.

As the devastation grows, Londoners flee to the countryside to find food. Edward blames the plague on garbage and human excrement piled up in London streets and in the Thames River. In the spring, 3, Jews defend themselves in Mainz against Christians but are overcome and slaughtered. The plague hits Wales, brought by people fleeing from Southern England, and eventually kills, people there.

Scotland, having so far avoided the plague, hopes to take advantage of English weakness by amassing an army and planning an invasion. While waiting on the border to begin the attack, troops became infected, with 5, dying. Choosing to retreat, the soldiers bring the disease back to their families and a third of Scotland perishes. All total, Europe has lost about 50 percent of its population.

With the Black Death considered safely behind them, the people of Europe face a changed society. The combination of the massive death rate and the numbers of survivors fleeing their homes sends entrenched social and economic systems spiraling. It becomes easier to get work for better wages and the average standard of living rises. With the feudal system dying, the aristocracy tries to pass laws preventing any further rise by the peasants, leading to upheaval and revolution in England and France.

Significant losses within older intellectual communities brought on an unprecedented opportunity for new ideas and art concepts to take hold, directly leading to the Renaissance and a more youthful, enlightened period of human history.
