Russian health authorities refuted claims of a second individual falling ill following the death of a worker at a plague research facility in Siberia. The regulator dismissed what it termed as “misinformation circulating on social media regarding a second illness.” They confirmed thorough screenings of all contacts of the deceased individual, stating that no infectious diseases were identified, with nearly 5,000 laboratory tests showing no harmful pathogens.
The deceased, identified as Daria Shipilova, succumbed to pneumonia of unknown origin at the Irkutsk Anti-Plague Research Institute in Siberia. Prompted by this incident, Russian authorities swiftly implemented precautionary anti-epidemic measures. The World Health Organization initially assessed the public risk as low, emphasizing the lack of comprehensive information from Russian authorities for a full risk evaluation.
Rospotrebnadzor, Russia’s health watchdog, clarified that the deceased worker had been vaccinated against the dangerous infections present at the laboratory. International health bodies, including Health Canada and the U.S. Centers for Disease Control and Prevention, have been monitoring the situation closely. Both countries reported minimal risk to their populations, with no recorded cases of plague in Canada since 1939 and the U.S. maintaining low concern for an unconfirmed pneumonic plague case in Siberia.
As investigations continue, health agencies are prepared to conduct screenings and monitor travelers from the affected region. Notably, direct flights between Russia and the United States have been halted since the onset of the conflict in Ukraine in 2022.
