Did a Russian lab accidentally leak a type of plague with one person already deceased

Majority view

Authoritative reporting confirms that a 28-year-old worker at Russia's Irkutsk Anti-Plague Research Institute died after severe pneumonia of unknown origin, while reports alleged that she broke a test tube containing plague bacteria. Russian health authorities denied confirming plague or a laboratory leak and said testing found no microorganisms linked to her work. Therefore, the death is confirmed, but the alleged accidental plague leak and causal connection remain unproven.

Credible dissent

Independent and international media reported the alleged broken test tube and possible plague exposure, while Russian authorities specifically denied that a hazardous-pathogen incident occurred and did not identify plague as the cause of death.
