Russian Researcher's Death Sparks Plague Scare in Siberia

A 28-year-old researcher has died in Siberia after a suspected lab accident, prompting Russian authorities to place around 200 people under medical observation for possible plague, while the White House monitors the case. The cause of death remains officially unconfirmed. Daria Shipilova, a technician at the Irkutsk Anti-Plague Research Institute, died on October 2 after being hospitalized with severe pneumonia. An unconfirmed report claims she broke a test tube containing live plague bacteria on September 25, though Russian officials have not verified this account. No human-to-human transmission has been confirmed, and all monitored contacts have tested negative. Russian officials maintain the epidemiological situation is stable, while a US-based Russian epidemiologist has questioned the lab accident theory, suggesting undisclosed details may exist.
