Will a new pneumonic plague case be confirmed in Russia by October 15?

Analysis

Russia's public health watchdog, Rospotrebnadzor, said on October 5 that an Irkutsk anti-plague institute employee had been diagnosed with "pneumonia of unknown etiology." It also said extensive testing found "no microorganisms associated with the patient's professional activities." That is a long way from a confirmed plague diagnosis. International accounts are cautious too. The World Health Organization said, as reported on October 5, that the cause of the worker's death had not been officially confirmed and that laboratory testing was understood to be underway. A US statement reported on October 6 referred to a "suspected" case of pneumonic plague. Suspected status does not meet the bar here, and this particular patient is excluded from the question anyway. What matters for a Yes is a separate person, with pneumonic involvement explicitly confirmed and published by October 15. Reports indicate that testing of the woman's contacts found no dangerous infectious pathogens. Two contacts reportedly tested positive for a common cold virus and two for COVID-19. That is reassuring about onward spread, though the supplied research cannot rule out a case elsewhere in Russia. The forecast leans firmly toward no new confirmed case, mainly because the one known episode has not been tied to plague by officials, and no second case is in the evidence reviewed. Some uncertainty remains because testing was reported as ongoing. The thing to watch is any Rospotrebnadzor or regional announcement of a new patient explicitly confirmed with pneumonic plague.
