The Bubonic Plague in Europe, Asia & Africa: Facts & Impact

What Was True About the Pandemic:

• Cause: Bacterium Yersinia pestis, transmitted by fleas on rodents.
• Symptoms: Fever, chills, swollen lymph nodes (buboes), skin blackening (gangrene).
• First Major European Wave (Black Death, 1347–1351): Killed 75–200 million (30–60% of Europe’s population).
• Spread to Asia & Africa: Estimated >100 million deaths across both continents via trade routes.
• Historical Impact: Profound demographic, economic, social upheaval; spurred quarantine systems, public health boards, labor‑market shifts, religious questioning.
• Modern Status: Still exists (rodent reservoirs in parts of Africa, Asia, Americas); treatable with antibiotics if caught early, but can be fatal without prompt care.

The plague reshaped the medieval world and remains a cautionary tale of zoonotic disease.
