Russia's health watchdog claims an Irkutsk lab worker died of pneumonia, denying plague rumors despite conflicting statements from regional officials.
Russian health consumer watchdog Rospotrebnadzor has denied that a 28-year-old laboratory worker in Irkutsk died from pneumonic plague, attributing her death instead to "pneumonia of unknown origin." The agency reported that extensive laboratory testing detected no plague-related microorganisms in samples taken from the deceased.
The official denial directly contradicts earlier statements made by Alexei Tsydenov, governor of the neighboring Buryatia region, who claimed the technician had died from plague. Local media reports indicate that nearly 200 contacts remain under medical observation, with multiple medical facilities previously placed under quarantine.
The conflicting official statements have fueled widespread public speculation regarding a potential laboratory accident, while international health authorities remain attentive to the situation in Siberia.
