Bubonic Plague Symptoms
In the early 1330s an outbreak of deadly bubonic plague occurred in China. The bubonic plague mainly affects rodents, but fleas can transmit the disease to people. Once people are infected, they infect others very rapidly. Plague causes fever and a painful swelling of the lymph glands called buboes, which is how it gets its name. The disease also causes spots on the skin that are red at first and then turn black.
Since China was one of the busiest of the world's trading nations, it was only a matter of time before the outbreak of plague in China spread to western Asia and Europe. In October of 1347, several Italian merchant ships returned from a trip to the Black Sea, one of the key links in trade with China. When the ships docked in Sicily, many of those on board were already dying of plague. Within days the disease spread to the city and the surrounding countryside.
In winter the disease seemed to disappear, but only because fleas--which were now helping to carry it from person to person--are dormant then. Each spring, the plague attacked again, killing new victims. After five years 25 million people were dead--one-third of Europe's people.

Bubonic plague symptoms can occur within two to six days of being infected by the bacteria Yersinia pestis (Yersinia pestis is a Gram-negative rod-shaped bacterium. It is a facultative anaerobe that can infect humans and other animals). If left untreated, symptoms, such as vomiting, abdominal pain, and diarrhea, can progress rapidly to septicemic plague (is a deadly blood infection, one of the three main forms of plague). Approximately 10 to 20 percent of people with bubonic plague symptoms will also develop symptoms in the lungs. This is called pneumonic plague, and is often fatal.
An Introduction to Bubonic Plague Symptoms:
When a person becomes infected with the bacteria that cause bubonic (Yersinia pestis), the bacteria begin to multiply within the lymph system. (The lymph or lymphatic...
