Summary

Story summary

Researchers from USF and FAU identified Yersinia pestis as the cause of the Plague of Justinian, the first known pandemic.
Genomic evidence from human remains in Jerash, Jordan, confirms the plague's presence in the Byzantine Empire (AD 550-660).
Genetic analysis shows nearly identical Y. pestis strains among victims, indicating a rapid outbreak.
The study emphasizes the historical impact of pandemics, contrasting with COVID-19's single spillover event.
The team plans further research in Venice, Italy, to investigate early public health measures and pathogen evolution.
