Has plague returned to Siberia? Panic grips Russia after lab worker's death
Rumours of a plague outbreak spread through Russia's Irkutsk region after a laboratory assistant died following an accident with a dangerous pathogen. Authorities call the situation stable, but conflicting statements have fuelled public fear.
Residents of Russia's Irkutsk region have grown alarmed over fears of a pneumonic plague outbreak after an employee of the Irkutsk Research Anti-Plague Institute died in early October. Darya Shipilova, 28, passed away in the intensive care unit of a hospital in Shelekhov. Local media report she had been working with dangerous pathogens and had broken a test tube containing the bacterium Yersinia pestis shortly before falling ill.
In response, authorities introduced quarantine measures, placing roughly 200 people under close medical observation. Several hospitals in the region were temporarily closed and quarantined, with restrictions expected to last up to three weeks. Face masks became mandatory at an aluminium plant in Shelekhov, kindergartens reportedly handed out masks to children, and residents said they had seen people wearing full protective suits in the streets.
Shipilova specialised in research into dangerous pathogens. According to colleagues and independent media, she accidentally broke a vial containing live biological material on 25 September. Two days later her condition deteriorated rapidly; doctors initially suspected a severe coronavirus case before switching to testing for highly dangerous infections once her symptoms failed to match. She was placed on a ventilator but could not be saved.
The severity of the response was underscored when Rospotrebnadzor chief Anna Popova rushed to the hospital and joined an emergency meeting of the regional sanitary commission led by Governor Igor Kobzev. For the first 24 hours, officials avoided the word "plague", instead referring to a "particularly dangerous infection". A neighbouring district briefly urged residents not to travel to Shelekhov over plague fears before deleting the warning. The head of the Buryatia republic initially linked the death to plague before softening his wording.
On Sunday, Rospotrebnadzor stated the sanitary situation in the region was stable and attributed the death to "pneumonia of unknown origin", saying further testing found no pathogens connected to her professional work. A prominent epidemiologist, Gennady Onishchenko, tried to reassure the public by noting that plague-carrying rodents and fleas in Siberia typically enter winter dormancy by early October — though this did little to calm public anxiety.
