On October 2, 2026, a 28-year-old laboratory worker named Darya Shipilova at an anti-plague research institute in Irkutsk, Siberia, died under mysterious circumstances after falling ill. Russian health officials quarantined dozens of people and conducted nearly 5,000 lab tests without finding any plague cases among contacts of the deceased; however, Russia's health watchdog maintains there is no risk of an epidemic. The WHO has urged Russia to provide more details about the incident due to insufficient information to assess public risk accurately.

Story summary
A 28-year-old lab technician named Darya Shipilova died of pneumonic plague in Siberia after breaking a test tube at the Irkutsk Anti-Plague Institute on September 29, and was placed on a ventilator but could not be saved. As many as 200 people who had contact with her were put into quarantine to prevent further spread. The incident prompted Russia's Chief State Sanitary Doctor Anna Popova to travel over 2,600 miles from Moscow to take charge of the outbreak situation in Irkutsk.
The Russian government has not released an official statement on Shipilova’s death or confirmed the virus as pneumonic plague, though independent news organizations have reported this. Local authorities have imposed strict quarantine measures across Irkutsk district, including the Shelekhov District Hospital and a local aluminum plant. Governor Igor Kobzev urged residents to stay calm but did not specify the infection.
The U.S. State Department is monitoring the situation closely with the Centers for Disease Control and Prevention (CDC) and other federal agencies, calling on Russia to share accurate information promptly. The White House has also been assessing options in response to this outbreak. Despite concerns, former Rospotrebnadzor head Gennady Onishchenko downplayed the threat, suggesting widespread transmission is unlikely due to cooler seasonal temperatures.
