The medieval Silk Road brought a wealth of goods, spices, and new ideas from China and Central Asia to Europe. In 1346, the trade also likely carried the.

Caffa (now Feodosija, Ukraine) was established by Genoa in 1266 by agreement with the Kahn of the Golden Horde .It was the main port for the great Genoese merchant ships (16-20), which connected there to a coastal shipping industry to Tana (now Azov, Russia) on the Don River.Trade along the Don connected Tana to Central Russia, and overland caravan routes linked it to Sarai and thence to the. The Silk Road, a network of land and sea trade routes that connected China and the Far East with Europe from 130 B.C. to 1453 A.D., became a vital source for everything from fabric and leather. Plague likely entered Europe through the Genoese ships fleeing plague elsewhere. These 12 ships quickly spread plague throughout port cities in Europe, including Venice, Marseilles, and Pisa.

Scientists had identified the cause of AIDS—HIV—and. The plague, commonly known as the Black Death, is a disease that has caused significant damage and high death counts all over the world. It is believed to have come from Asia in the mid sixth century and followed shipping routes before making its first appearance in Europe (McNeil, 1976, p. 166)

Kaffa wasn't the only eastern trading port on the Black Death's path, but Genoa's ships took the blame for bringing the pestilence. Once it hit Europe, the Black Death moved fast, traveling at an average speed of 2.5 miles per day (4 kilometers per day) [source: Duncan, Scott].From the Mediterranean ports, the disease took two paths; one through France that eventually made its way to England. The Centers for Disease Control made a very clear statement ruling out casual transmission ( I.e. AIDS was not a plague) in 1983. The media chose to ignore this, as did President Reagan who chose instead to deny there was such evidence, purely for the sake of political expediency The facemask through the centuries 04:41. Mark Honigsbaum, a medical historian and author of books like The Pandemic Century, knows from face masks, going back to their first known medical use.

Pneumonic plague is more virulent or damaging and is an advanced form characterized by a severe lung infection. The infection can be transmitted from person to person via airborne droplets. When an endemic disease, such as Ebola or plague, is introduced to a new geographic area that is densely populated with international shipping routes, it increases transmission rates and leads to severe outbreaks and potential pandemics

Cholera. While plague shaped much of Ottoman history over a longer period of time, the Ottoman experience with epidemic diseases in the 19 th century was dominated by recurring pandemics of cholera. Cholera, unlike plague, was a completely new disease for which the Ottomans, like much of the world for most of the nineteenth century, initially.

Credit for discovering the bacterial cause of plague is accorded to the French physician Alexandre Yersin (1863-1943), for his bacteriological investigations in June 1894 in Hong Kong during a deadly epidemic [].However, credit was not given to Yersin initially, and nor in the ensuing years by everyone, because he. Clinical plague infection manifests itself in three forms, depending on the route of infection: bubonic, septicaemic, and pneumonic. The bubonic form is the most common, resulting from the bite of an infected flea. The pneumonic form initially is directly transmitted from human to human via inhalation of infected respiratory droplets

As such, plague is maintained in so-called wildlife reservoirs where it is spread mainly among rodent species by fleas, and through which it is occasionally transmitted to human populations Urban areas that are a major transportation hub for shipping and recreation are at high risk for transmitting plague to nearby countries. The elevation of the mountains where most of the agriculture takes place, in addition to the ideal climate that allows rats and fleas to prosper, scientists have seen plague thrive in Madagascar's climate. Plague is one of the deadliest diseases in human history, second only to smallpox. A bacterial infection found mainly in rodents and associated fleas, plague readily leaps to humans in close contact

Challenging the Predominant Theory of the Black Death. The Black Death is among the most important events that shaped the middle ages. It had an undeniable impact on many of the great minds of that era and was the biggest turning point in the entire 1,000-year span of the medieval period. The Black Death wiped out up to half of the population A pinpoint in the history of pandemics is the first recorded outbreak of the plague, the plague of Justinian (541-542 AD, with recurrences until 750 AD), which was carried over the Mediterranean Sea from Egypt to Constantinople. Fleas carrying the bacteria Yersinia pestis infected rats, and these plague-infected rodents travelled aboard grain. 6 Climate Change.
