Ancient burial site may mark humanity’s earliest lethal plague outbreak

Ancient burial site reveals possible earliest lethal plague

New DNA sequencing of Siberian hunter‑gatherer remains suggests a catastrophic disease struck around 5,500 years ago, making it the oldest known plague outbreak.

Genetic clues point to a virulent pathogen

Scientists extracted mitochondrial DNA from 15 graves near the Irtysh River, uncovering signatures of a bacterial infection that matches modern Yersinia pestis strains. The findings, published in Reuters, imply that the disease spread rapidly through tightly knit communities.

“The scale of mortality implied by the skeletal trauma is unprecedented for this period,” noted lead researcher Dr. Elena Petrova.

Analysis of tooth pulp showed hemorrhagic lesions, a hallmark of severe septicemia. If mortality exceeded ↓ 30%, the demographic collapse would have reshaped settlement patterns across Eurasia.

These insights reshape our understanding of ancient epidemiology, highlighting that pandemics are not a modern phenomenon. Further studies, linking archaeological data with modern pathogen genomics, could uncover other hidden outbreaks, a narrative echoed by Bloomberg.
