Norwegian expert warns of possible engineered plague after Russian lab death
A Russian laboratory technician died shortly after developing severe lung symptoms, prompting a Norwegian plague researcher to warn of a potentially genetically modified, antibiotic-resistant bacterium.
A laboratory accident in Irkutsk involving technician Darja Sjipilova, aged 28, led to her death after she experienced acute lung symptoms within 48 hours. Russian officials describe the fatal illness as an unidentified pneumonia, rejecting claims of pneumonic plague, a stance challenged by the World Health Organization, the United States and the deceased’s mother. The incident triggered quarantine measures for roughly 200 individuals and the shutdown of multiple hospitals.
Norwegian plague researcher Nils Christian Stenseth cautioned that the bacterium involved might be a genetically altered Yersinia pestis strain possessing antibiotic resistance, emphasizing that research on such pathogens is typically conducted in closed, military-controlled labs. He added that only a small aerosol dose is needed for infection and that while plague could theoretically be weaponised, its practical use as a bioweapon is limited. Stenseth called for independent genetic testing of samples to verify the pathogen’s nature.
