The Trump administration is monitoring reports of a suspected plague case and related quarantines in Russia. A Trump administration official told Axios the government is “aware, monitoring the outbreak, and assessing options.” The State Department told NewsNation it was “aware of reports of a fatal case of suspected pneumonic plague in Irkutsk Oblast, Russia,” and was monitoring the situation with the Centers for Disease Control and Prevention and other interagency partners, adding that “many details have not been confirmed” and encouraging Russian authorities to share accurate information quickly and openly. Secretary of State Marco Rubio told reporters the US was monitoring a possible outbreak after a lab worker died. [ 1 , 3 , 4 ]
The case involves a 28-year-old researcher, Daria Shipilova, who worked at an anti-plague research institute in Russia's Irkutsk region. Local reports said that on Sept. 25 she broke a test tube containing the pneumonic plague pathogen, according to Axios. The New York Post reported that she was hospitalized in Shelekhov with symptoms of severe pneumonia, placed on a ventilator and then died on Thursday, and that she fell ill while on an expedition with other researchers near Russia's border with Mongolia. According to the news outlet Lyudi Baikala, she told medical staff she had accidentally broken a test tube containing live bacteria while collecting samples. [ 1 , 2 ]
Russian officials have not confirmed that she contracted plague. Regional Gov. Igor Kobzev declined to identify the illness, referring to it only as “a dangerous infectious disease,” and canceled all public events in the region, the New York Post reported. Russia's public health agency said she had “pneumonia of unknown etiology” and that further testing found no microorganisms linked to her work, and said the situation in the region is stable, according to the New York Post and The Hill. Authorities quarantined an entire hospital and placed people who had come into contact with her under medical observation; none of those identified showed symptoms and their test results came back negative, the New York Post reported. NBC News reported that around 200 people in Siberia were facing medical observation. [ 2 , 3 ]
The State Department said plague is “a known disease and is treatable with common antibiotics, especially when treatment starts early,” The Hill reported, and that cases occur naturally in many parts of the world. According to the CDC, pneumonic plague is “a rare and often fatal disease that can be transmitted by respiratory droplets from animals or persons infected with Yersinia pestis bacteria.” White House spokespeople referred questions to the State Department, which did not respond to an Axios request for comment; the State Department later gave a statement to NewsNation. Anna Popova, who heads Russia's public health watchdog, traveled 2,600 miles from Moscow to the Irkutsk region after receiving news of the infection, the New York Post reported. [ 1 , 2 , 3 ]
Why it matters
A suspected plague death at a Russian research facility drew US government attention because of the disease's potential to spread and because Russian authorities have released few confirmed details. The State Department said many details have not been confirmed and urged Russian authorities to share accurate information, while noting plague is treatable with common antibiotics when treatment starts early. The New York Post noted fears that the situation could resemble COVID-19, which it said is widely believed to have started at a disease research facility.
