New DNA Evidence Reveals Why the Black Death Spread So FAST

The Black Death was not only the deadliest pandemic in history it was also one of the fastest. Between 1347 and 1351 it killed nearly half of Europe, North Africa, and the Middle East. But how did it spread with such terrifying speed?

For centuries, people believed rats and fleas were the main culprits. But ancient DNA has revealed a far more unsettling truth: humans themselves carried the plague. In their bodies, their clothes, and even their breath, they became the real engine of transmission.

This documentary explains how Yersinia pestis, trade routes, crowded medieval cities, and human networks created the perfect storm. It shows why the Black Death moved so fast and why its lessons still matter today.
