Archaeological discoveries indicate plague was present in human populations five thousand years ago. Evidence suggests the disease affected hunter-gatherer communities in Siberia, specifically impacting children. The findings challenge previous understandings of the disease’s historical timeline, pushing its emergence back significantly. Researchers determined the sparse population of these early communities did not offer protection from the deadly infectious disease. This discovery provides new insights into the long-term relationship between humans and *Yersinia pestis*, the bacterium responsible for plague. The research highlights the vulnerability of even small, isolated groups to widespread epidemics throughout history.
