Siberian plague lab worker's death triggers hospital quarantines in Irkutsk region

A woman who worked at a Russian anti-plague institute in Irkutsk, Siberia, died on October 2nd, prompting quarantine measures at several hospitals in the region amid uncertainty over the cause of her death. Darya Shipilova, in her late twenties, fell ill two days before dying at a hospital in Shelekhov. Unconfirmed reports suggest a possible lab accident, but officials have not confirmed this, and tests found no micro-organisms linked to her work, with her death attributed to pneumonia of unknown origin. Precautionary measures include hospital quarantines, a mask requirement at a local smelter, and cancelled public events. Russian health officials have downplayed the risk, while US authorities have urged Russia to share accurate information, noting plague remains endemic in parts of Siberia but human cases are rare.
