Russian lab death raises plague research concerns

A technician at Russia's Irkutsk Antiplague Research Institute reportedly died after a lab accident involving pneumonic plague bacteria, triggering global alarm and a lockdown of nearly 200 people in medical isolation. Russian authorities deny any leak, attributing the death to pneumonia of unknown cause. The institute's outdated English website lists its study of dangerous pathogens like plague, anthrax, and cholera, and details its international collaborations with Mongolia and China. The incident has prompted US Secretary of State Marco Rubio to demand Russia share accurate information openly, while biosecurity experts warn of the dual-use potential of Soviet-era facilities. The website also advertises an upcoming CIS conference on plague prevention in October 2026, and the deceased technician's research focused on antibiotic resistance in plague bacteria, raising concerns about engineered strains. Moscow and Rospotrebnadzor maintain no pathogens linked to her work were found.
