President Donald Trump says the United States is looking "very strongly" at the death of a Russian plague research technician in Siberia, an incident that could raise concerns about the spread of pneumonic plague.
Secretary of State Marco Rubio added that Washington is watching the situation closely, stressing that while there is no immediate cause for alarm, it remains a focus for monitoring and containment measures.
Irkutsk’s governor reported that investigations identified no microorganisms linked to the technician’s work in her biological samples, describing the cause of death as "pneumonia of undetermined etiology".
Unconfirmed reports suggested the technician fell ill after either breaking a test tube containing the pathogen or after a field trip to the Buryatia region, where plague naturally occurs among wild rodents.
When asked whether Washington had spoken to the Kremlin about the risk, Trump said, "I hate to see them having it," but added that the United States would offer assistance to those affected.
According to Irkutsk’s governor Igor Kobzev, there have been no other cases of staff at the Anti‑Plague Institute seeking medical attention since the technician’s death, a point confirmed by Russia’s consumer and health watchdog Rospotrebnadzor.
Rospotrebnadzor’s biological safety team inspected the institute and found no emergency situation. Kremlin spokesman Dmitry Peskov urged the public to rely on official statements rather than rumors.
Russian media report that nearly 200 people who had contact with the deceased are under medical observation as a precaution.
Secretary of State Rubio further explained that the potential spread could be contained internally through quarantine, and that the situation does not warrant lockdowns or widespread panic akin to COVID‑19.
Yersinia pestis, the bacterium behind pleumasic illnesses, is still present in parts of the world and can be tackled with antibiotics, of which experts warn that the virus is capable of person‑to‑person transmission if left untreated. The bacterium is a long‑standing threat that continues to necessitate rigorous research and monitoring.
