Russia says no epidemic risk as WHO pushes for transparency on plague lab death

A lab worker at a Russian plague research institute in Siberia, 28-year-old Darya Shipilova, died on October 2, 2026, after developing an unexplained form of pneumonia. Initial media reports suggested a possible contraction of pneumonic plague following a lab accident at the Irkutsk Anti-Plague Research Institute, with some reports quickly removed. This raised international concerns about a potential epidemic, prompting global leaders to call for greater transparency from Russia.

Russian authorities, through their health watchdog Rospotrebnadzor, have since downplayed the risk of an epidemic, attributing Shipilova's death to "pneumonia of unknown origin" and stating that no cases of plague have been detected in the region. Approximately 200 individuals who had contact with Shipilova were quarantined, with Russian officials reporting that over 90% have been released after tests revealed no dangerous pathogens. Precautionary measures are reportedly being wound down in the Irkutsk region.

Despite Russia's assurances, the World Health Organization (WHO) has pressed for more comprehensive and transparent information, indicating that the details provided thus far hinder a full risk assessment. While initially assessing the public health risk as low, the WHO has updated its evaluation due to the ongoing lack of clarity. Former US President Donald Trump stated his intention to speak with Russian President Vladimir Putin regarding the incident, and the US, through Secretary of State Marco Rubio, formally requested more information from Moscow, emphasizing Russia's obligations under international health regulations.
