What were Buboes?
Buboes are a symptom of bubonic plague, and occur as painful swellings in the thighs, neck, groin or armpits. They are caused by Yersinia pestis bacteria spreading from flea bites through the bloodstream to the lymph nodes, where the bacteria replicate, causing the nodes to swell.
Who spread the bubonic plague?
Carried by the fleas on rats, the plague initially spread to humans near the Black Sea and then outwards to the rest of Europe as a result of people fleeing from one area to another.
