Answer 1

The most responsible for the spread of the bubonic plague across Eurasia was sailors. They played a key role in the movement of the disease through trade routes, particularly along maritime pathways. While fleas and rats were critical in the transmission of the plague bacterium, it was the movement of people, including sailors, that facilitated the rapid spread across regions.
