Mortality from bubonic plague today is between 1% and 10%, whereas septicemic plague may have mortality as high as 50% — and if untreated, it's over 90%. Fleas can spread other diseases too
The plague is considered the likely cause of the Black Death that swept through Asia, Europe, and Africa in the 14th century and killed an estimated 50 million people, [1] [10] including about 25% to 60% of the European population.

The Black Death was a bubonic plague pandemic that occurred in Europe from 1346 to 1353. It was one of the most fatal pandemics in human history; as many as 50 million people [2] perished, perhaps 50% of Europe's 14th century population. [3] The disease is caused by the bacterium Yersinia pestis and spread by fleas and through the air.

[1] The total reported number of cases of all types of plague in 2013 was 783. [2] Left untreated, pneumonic plague is always fatal. [3]
