Bubonic Plague - 1450 in humans, caused by a short, thin Gram-negative bacillus. In humans, plague occurs in three forms: bubonic plague, pneumonic plague and septicemic plague. The best-known form is bubonic plague and is named for the buboes, or enlarged and inflamed lymph nodes, characteristic of plague in the groin, neck or armpits. Bubonic plague can only be transmitted through the bite of one of several insects that normally parasitize rodents and seek new hosts when the original host dies. If the plague is left untreated, it is fatal in thirty to seventy-five percent of all cases. Mortality in treated cases is only five to ten percent. History of Bubonic Plague The origin of bubonic plague is unknown but it may have started in Africa or India. Colonies of infected rats were established in northern India many years ago. Some of these rodents had infected traders on the route between the Middle East and China. After 1330, the plague invaded China. From China it was transferred west by traders and Mongol armies in the 14th century. As these traders traveled west, they followed a more northerly route across the grasslands of what is now Russia, establishing a large population of infected rodents there. In 1346, the disease reached the Crimea and made its way to Europe in 1347. The epidemic in Europe was a devastating catastrophe, which resulted in more than 25 million deaths, or approximately twenty-five percent of the total population of the continent.
