What is driving the attention?
Scientific research has uncovered evidence that plague outbreaks caused by Yersinia pestis impacted hunter-gatherer groups near Lake Baikal over 5,500 years ago, significantly predating previous estimates. These studies detail immune system evasion strategies of the plague bacteria and trace connections between Yersinia strains in animals and human infections. This new understanding resets the timeline of historic plague outbreaks and informs current knowledge of infectious disease evolution.
