  • Maybe Rats Aren't to Blame for the Black Death

    A provocative new study suggests that medieval plagues spread via fleas and lice on people.Rats have long been blamed for spreading the parasites that transmitted plague throughout medieval Europe and Asia, killing millions of people. Now, a provocative new study has modeled these long-ago outbreaks and suggests that the maligned rodents may not be the culprits after all. The study, published on Monday in the journal PNAS, instead points the finger at human parasites—such as fleas and body lice—for primarily spreading plague bacteria during the Second Pandemic, a series of devastating outbreaks that spanned from the 1300s to the early...

    When the Black Death swept through Europe in 1347, it was one of the deadliest disease outbreaks in human history, eventually killing between a third and half of Europeans. Prior work by investigators has traced the cause to plague-carrying fleas borne by rats that jumped ship in trading ports. In addition, historical researchers believe that famine in northern Europe before the plague came ashore may have weakened the population there and set the stage for its devastation. Now, new research using a unique combination of ice-core data and written historical records indicates that the cool, wet weather blamed for the...

    Medieval Plague May Explain Resistance to HIV LONDON (Agence de Presse Medicale) - The persistent epidemics of hemorrhagic fever that struck Europe during the Middle Ages provided the selection pressures that have made 10 percent of Europeans resistant to HIV infection, according to a UK study. A mutation called delta-32 in the cellular receptor dubbed CCR5 protects against HIV infection, and is found more often in Europeans than other populations. Scientists have previously suggested that the genetic mutation became common because it protected people against the Black Death or smallpox epidemics, while those with normal CCR5 were wiped out. But...

    By The Week Staff August 30, 2014Think Ebola is alarming? Scientists expect a much deadlier virus to emerge in the not-distant future. How likely is a pandemic? Epidemiologists believe we're statistically overdue for a global viral outbreak, which occurs every generation or so. This year's Ebola crisis is probably just a dress rehearsal: Though the virus has killed at least 1,420 people in Africa in the last five months, Ebola is transmitted only through intimate contact with bodily fluids and doesn't have the global reach of a true pandemic, such as Spanish influenza in 1918. Humanity had no prior exposure...

    Europe's chill linked to disease By Kate Ravilious Bubonic plague may have wiped out over a third of Europe's population Europe's "Little Ice Age" may have been triggered by the 14th Century Black Death plague, according to a new study. Pollen and leaf data support the idea that millions of trees sprang up on abandoned farmland, soaking up carbon dioxide from the atmosphere. This would have had the effect of cooling the climate, a team from Utrecht University, Netherlands, says. The Little Ice Age was a period of some 300 years when Europe experienced a dip in average temperatures. Dr...

The Black Death was a catastrophe which wiped out nearly half the European population, with 20m people dying between 1348 and 1350. But new research being carried out by a team from Liverpool University has shown that the disease may have produced an unexpected side-effect - resistance to the deadly HIV/Aids virus. Professor Christopher Duncan and Dr Susan Scott have already caused shockwaves among historians with their claim that the Black Death was caused...

    Y. pestis was the notorious culprit behind the sixth century's Plague of Justinian, the Black Death, which killed 30%-50% of the European population in the mid-1300s, and the Third Pandemic, which emerged in China in the 1850s. Earlier putative plagues, such as the Plague of Athens nearly 2,500 years ago and the second century's Antonine Plague, have been linked to the decline of Classical Greece and the undermining of the Roman army. However, it has been unclear whether Y. pestis could have been responsible for these early epidemics because direct molecular evidence for this bacterium has not been obtained from...

    A mass burial site that may contain 30 victims of the Great Plague has been discovered in the City of London. The skeletons were found during excavation of the Bedlam burial ground at Liverpool Street, which will serve the cross-London Crossrail line. A headstone found nearby was marked 1665. Scientists hope to establish whether bubonic plague or some other pestilence was the cause of death. The skeletons will be analysed by the Museum of London Archaeology. Archaeologists said the fact the individuals appear to have been buried on the same day suggest they were victims of the Plague. Crossrail lead...

    Gerbils are cute and furry creatures. They may also, according to scientists, have been responsible for killing millions of people across Europe by spreading the plague. Researchers now believe that gerbils from Asia, rather than native black rats, were behind the repeated outbreaks of the bubonic plague in Europe.

At least 119 cases were confirmed by late last year, including 40 deaths, the World Health Organization said in a statement. And the disease is taking an alarming turn. "The outbreak that started last November has some disturbing dimensions," the WHO said this week. "The fleas that transmit this ancient disease from rats to humans have developed resistance to the first-line insecticide."

    Most people assume that the fourteenth-century Black Death that quickly ravaged the western world was a bacterial bubonic plague epidemic caused by flea bites and spread by rats. But the Black Death killed a high proportion of Scandinavians where it was too cold for fleas to survive. Biology of Plagues. Evidence from Historical Populations published by Cambridge University Press, analyzed 2,500 years of plagues and concluded that the Black Death was caused by a viral hemorrhagic fever pandemic similar to Ebola. If this is correct, the future medical and economic impacts from Ebola have been vastly underestimated.  Authors Dr. Susan Scott, a demographer,...

    Things seem to be looking up for rats. After more than 500 years, rats may be off the hook for causing the Black Death, the horrible plague that claimed up to 60% of the European population. In virtually every textbook the Bubonic Plague, which is spread by flea-ridden rats, is named as the culprit behind the chaos. But mounting evidence suggests that an Ebola-like virus was the actual cause of the Black Death and the sporadic outbreaks that occurred in the following 300 years. At the forefront of this theory are two researchers from the University of Liverpool, Dr. Christopher...

    In the 1200’s in Europe something began to change. Most of the wealth of Europe came from the produce of land. Pollen evidence, as well as glacial evidence, prove that from 750 AD to 800 AD, and again two hundred years later from 1150 AD to 1200 AD, Europe’s weather suddenly starting warming, known as the “Medieval Warm”. Pollen studies of the beech forests along the Fernau glacier and in the Ardenes region of Northern France prove that these forests started to expand their borders during the late Eight Century from their A.D. 200 borders, and we discover that Alpine...

    A prolonged period of wet weather spurred the spread of the Bubonic plague in medieval times, according to a new study. And a 300-year spell of unpredictable weather coincided with the decline of the Roman Empire. Climate change wasn't necessarily the cause of these and other major historical events, researchers say. But the study offers the most detailed picture yet of how climate and society have been intertwined for millennia. Again and again, the data suggest, climate has impacted culture in dramatic ways. Unusually extreme and frequent shifts in weather patterns between 250 and 550, for example, coincided with a...

    An extensive study of tree growth rings says there could be a link between the rise and fall of past civilisations and sudden shifts in Europe's climate. A team of researchers based their findings on data from 9,000 wooden artifacts from the past 2,500 years. They found that periods of warm, wet summers coincided with prosperity, while political turmoil occurred during times of climate instability. The findings have been published online by the journal Science. "Looking back on 2,500 years, there are examples where climate change impacted human history," co-author Ulf Buntgen, a paleoclimatologist at the Swiss Federal Research Institute...
