Rospotrebnadzor, the Russian equivalent of the U.S. Centers for Disease Control and Prevention, issued a statement last night: "The sanitary and epidemiological situation in the Irkutsk region and the cities of Irkutsk and Shelekhov is stable. A special set of measures has been organized and implemented in response to the case of an employee of the Irkutsk Anti-Plague Institute of Siberia and the Far East who has been diagnosed with pneumonia of unknown etiology.” As you might guess, Russian authorities don’t issue a “don’t worry, no plague here” statement unless people are worried that there is a risk of plague.
