A Russian infectious disease researcher died from unexplained pneumonia at the Irkutsk Anti-Plague Research Institute, prompting mass quarantine measures affecting roughly 200 people under observation and several hospitals placed in isolation. Unconfirmed reports suggest she may have been exposed to Yersinia pestis during a lab incident on September 25. Russian health officials have stated the infection was most likely not plague, while neighbors face ongoing monitoring.
Background
