The contagion that is believed to have caused the Black Death (Yersinia pestis) can still be found today, but it is rarely fatal

The Black Death was one of the most devastating pandemics in human history, resulting in the deaths of an estimated 75 to 200 million people in Eurasia and peaking in Europe from 1347 to 1351

The best-known symptom of bubonic plague is one or more infected, enlarged, and painful lymph nodes, known as buboes

The Black Death is estimated to have killed 30–60% of Europe's total population

The plague disease is commonly present today in populations of fleas carried by ground rodents in areas including Central Asia, Western Asia, Northern India and parts of Africa

Bubonic plague is mainly spread by infected fleas from small animals
