Humans Suffered from Plague by at Least 5,000 Years Ago

(p. D4) Historians and microbiologists alike have searched for decades for the origins of plague. Until now, the first clear evidence of Yersinia pestis infection was the Plague of Justinian in the 6th century, which severely weakened the Byzantine Empire.
But in a new study, published on Thursday [Oct. 22, 2015] in the journal Cell, researchers report that the bacterium was infecting people as long as 5,000 years ago.
