                                BBUBONIC PLAGUE

The summary of this book is that in the year 541 and many people began to die from a strange disease where the symptoms were fever.  Lymph nodes in a person's neck, armpits, or thighs have swollen.  Purple spots appeared on the person's skin.  Some people also had black blisters called pustules.  If pustules appeared, the infected person died within a day.
 In October it spread to Constantinople.  The city of Constantinople was within the Byzantine Empire in present-day Istanbul, Turkey.  hymn mode: an organ with a strip containing white blood, which stops fighting

 The disease took almost 200 years to disappear, but by then around 25,000 people had died from this disease.

 A certain type of bacteria called Yersinia pestis causes bubonic plague.  Fleas, lice, and other insects that feed on animal blood carry the bacteria.
 Insects bite humans.  Then the bacteria enters a person's body.  Live animals live in water, soil or plants and in rodent animals.
 Bubonic plague affects a person's lymphatic system.  This system is a network of lymph nodes and organs that carry fluid throughout the body.  The liquid contains white blood cells, which help the body fight infection.  Swollen lymph nodes are a sign of infection.
 Bubonic plague can kill 40 to 70 percent of infected people if left untreated.  TYPES OF PLAGUE If bubonic plague is not treated, it can lead to worse forms of plague.  Plague bacteria can enter a person's bloodstream and cause septicemic plague.  This type of plague can kill a person's skin tissue.  Victims have fever, chills, and stomach pain.  The bacteria can also infect a person's lungs.  This type of plague is called pneumonic plague.
