Russian Plague Researcher's Death Sparks Lab Leak Fears in Siberia

A Russian plague researcher died October 2 from an unknown severe pneumonia, prompting the closure of five hospitals and the isolation of about 200 people in eastern Russia near the Mongolian border. The 28-year-old woman worked at the Irkutsk anti-plague research institute, which studies diseases like plague, anthrax, and cholera. Russian authorities say tests showed no signs of pathogens related to her work, though unconfirmed reports claim she accidentally broke a vial containing Yersinia pestis. The Norwegian Institute of Public Health is monitoring the situation, noting it cannot verify the plague reports. Neighboring countries Kyrgyzstan, Uzbekistan, and Kazakhstan have tightened border controls, while the US State Department urges Russia to share accurate information.
