White House Monitoring Suspected Plague Case in Russia
A Trump administration official told Axios that the White House is aware of the situation in Russia's Irkutsk region in Siberia.
"The administration is aware, monitoring the outbreak, and assessing options," the official said Sunday.
The case: Daria Shipilova, 28, a lab technician at the Irkutsk Anti-Plague Research Institute of Siberia and the Far East. The independent outlet Lyudi Baikala reported she broke a test tube containing plague bacteria on September 25, was hospitalized in Shelekhov on September 29 with severe pneumonia, and died overnight October 1 to 2. That account is unconfirmed.
What is confirmed and what isn't
Nearly 200 contacts were placed under medical observation or isolation, several medical facilities were quarantined, and mask requirements appeared in some workplaces. Governor Igor Kobzev said contacts showed no signs of illness and initial tests were negative.
Russia's health agency, Rospotrebnadzor, has not confirmed plague. It diagnosed pneumonia of unknown etiology, said expanded testing found no microorganisms linked to her work, found no lab accident in its review, and called the regional epidemiological situation stable.
Alexei Tsydenov, head of neighboring Buryatia, said the woman "died, maybe of the plague," while adding there were no plague outbreaks in Buryatia.
Separately, the State Department said it is aware of reports of "a fatal case of suspected pneumonic plague in Irkutsk Oblast" and is tracking the situation with the CDC and other agencies, urging Russian authorities "to share accurate information quickly and openly."
For context, the U.S. had a fatal pneumonic plague case in Arizona in 2025 with no secondary illnesses. Plague is bacterial and treatable with common antibiotics if caught quickly.
