Bubonic plague is one of three forms of the infectious disease caused by the Yersinia pestis bacteria. If left untreated, the bubonic plague, which is typically transmitted from animals to humans by fleas, has a fatality rate of 30 percent to 60 percent. This disease caused the Black Death and killed some 50 million people in the 14th century.
