7.5 Bundibugyo virus outbreak surges as Ebola relative reemerges

Bundibugyo virus, an Ebola relative, has surged in the Democratic Republic of Congo and Uganda with 695 confirmed cases and 138 deaths as of June 11, 2026, surpassing two earlier outbreaks in scale. Limited diagnostic capacity and delays in specimen transport delay isolation and contact tracing in affected regions.

  • 695 confirmed cases and 138 deaths as of June 11, 2026
  • Surpassed Uganda 2007 and DRC 2012 outbreaks in scale and trajectory
  • Spreads through direct contact with infected bodily fluids
  • Overlapping symptoms with malaria and typhoid; requires lab confirmation
  • Scarce laboratory resources in affected DRC regions; samples require long distances to national reference labs
  • Delays in testing impede isolation and contact tracing

7 Ancient DNA reveals plague's 400-year recurrence in Europe after the Black Death

Genetic analysis of 26 Yersinia pestis genomes from 11 archaeological sites across Estonia, Russia, England, the Netherlands, and Switzerland revealed plague repeatedly returned to Europe over 400 years following the Black Death. A major genetic expansion and branching into three lineages occurred around 1450–1500, likely influenced by the Great Renaissance Drought.

  • 26 ancient plague genomes reconstructed from 14th–18th centuries
  • Samples from 11 sites across Estonia, Russia, England, Netherlands, and Switzerland
  • Plague repeatedly resurfaced over 400+ years after Black Death (1347–1353)
  • Major genetic expansion into three lineages around 1450–1500
  • Estonia experienced repeated introductions beginning late 14th century
  • Plague spread via trade, migration, and war
