Ancient Plague Strains Discovered: Insights into Early Human Epidemics

Recent research has unveiled ancient strains of plague from 5,700 years ago in cemeteries near Lake Baikal, Siberia, marking the oldest known evidence of the disease in humans. The study, published in Nature, found that 39% of individuals in the examined cemeteries showed signs of plague infection, particularly affecting children aged 4 to 11. This discovery challenges previous theories about the spread of infectious diseases among hunter-gatherer communities, suggesting that plague could have caused significant mortality even before the bacterium developed efficient transmission methods. The findings urge a reevaluation of how early human societies dealt with disease outbreaks.

Key Details: • The study indicates a high infection rate of 39% among the examined individuals. • Plague strains are believed to have originated 5,700 years ago, predating previous known strains by nearly 2,000 years. • The findings highlight the tragic impact of plague on young children in these communities.
