US Watching Closely After Russian Plague Researcher Dies

The United States says it is monitoring a suspected outbreak after a laboratory technician died at the Anti‑Plague Institute of Siberia and the Far East in Irkutsk.

Secretary of State Marco Rubio explained that there was concern the incident “could have led to the spread of pneumonic plague,” but that the situation does not warrant public alarm.

The death was described as “pneumonia of undetermined etiology.” Irkutsk governor Igor Kobzev added that no micro‑organisms linked to the woman’s work had been detected in her biological samples.

Unconfirmed reports suggest the technician fell ill after either breaking a test tube containing the pathogen or after a field trip to Buryatia, a region where the plague bacterium Yersinia pestis is found in wild rodents.

No other staff at the institute have reported illness, a statement from Russia’s consumer and health watchdog Rospotrebnadzor confirmed. A biological‑safety team inspected the facility and found no emergency.

Kremlin spokesman Dmitry Peskov urged people to rely on official statements rather than rumours about the incident.

Over 190 people who had contact with the deceased were put under medical observation as a precaution, Russian media reported last week.

Rubio added during an interview that, “If something like that gets out, it can quickly spread. So we’re watching and monitoring it closely. I don’t think it’s cause for alarm, but it is cause for focus.”

Experts note that pneumonic plague can spread from person to person, but can be managed with antibiotics. Dr Simon Clarke of the University of Reading said that while some may fear a bioweapon angle, the likelihood of that is lower than the chance of accidental release.

The incident underscores the continued relevance of studying the plague, a disease that once decimated half of Europe’s population in the 14th century. The Anti‑Plague Institute was founded in 1920 in response to a bubonic outbreak.
