Bones, about 4,900 years old, are therefore the first sign of the human pandemic in history. According to experts at the University of Gothenburg, the epidemic occurred a few centuries earlier, 5,700-5,000 years ago, in the north of the Black Sea, and new trade routes contributed to the spread of the disease throughout Europe and Asia.

Thus, thanks to the wheel and animal traction, in addition to agriculture and economic inequalities, bacteria spread.
