Nearly 200 people have been quarantined and placed under medical observation after the death of a worker at a plague laboratory in Siberia, Russia. Russian media reported that the woman died of pneumonic plague, but health authorities have not yet confirmed that. Initial tests have found no evidence of a link between her death and the bacteria in the laboratory.
Daria Shipilova, 28, worked at the Irkutsk Anti-Plague Research Institute of Siberia and the Far East. She was hospitalized after falling ill on September 30. She died on October 2 in a hospital in the town of Shelekhov, near Irkutsk. Russian authorities cited "pneumonia of unknown cause" as the cause of her death.
