More than 60 workers remain isolated despite negative pathogen tests.
Irkutsk
Russian health authorities have denied reports that a 28 year old laboratory worker died from pneumonic plague after an alleged accident at an anti plague research institute in Siberia. The case has nevertheless raised questions because quarantine measures remain in place at multiple medical facilities and dozens of employees continue to be isolated.
Daria Shipilova worked at the Irkutsk anti plague institute and died last week. Regional media, citing anonymous sources close to local security services, reported that she may have been exposed after a test tube broke inside the laboratory. More than 60 institute employees were subsequently isolated inside the building.
Several hospitals in Irkutsk were also placed under quarantine, including major clinical hospitals, a children’s hospital and a maternity hospital. The Central District Hospital in Shelekhov, where Shipilova lived, was also closed, while mask requirements were introduced at an aluminum plant in the same area.
Russia’s federal health watchdog, Rospotrebnadzor, said laboratory testing of Shipilova’s biological material found no microorganisms associated with her professional activity. The agency also said no accidents involving pathogenic microorganisms had been recorded at the institute.
Testing among people who had contact with Shipilova identified two cases of COVID 19 and two rhinovirus infections, according to the authorities. No other infectious agents were reported. Irkutsk Governor Igor Kobzev said a commission of specialists concluded that Shipilova died from pneumonia of unknown etiology and described the regional sanitary situation as stable.
Conflicting official messages have contributed to uncertainty. The head of neighboring Buryatia initially stated that Shipilova had died from plague before later qualifying the statement as a possibility. Regional authorities in Irkutsk also briefly published a warning advising residents not to travel to Shelekhov because of plague, but the message was later removed.
Kremlin spokesman Dmitry Peskov urged the public to rely on official statements from Rospotrebnadzor rather than rumors and speculation.
One issue remains unresolved in the public account. Authorities have not fully explained why extensive isolation measures and simultaneous hospital restrictions were introduced if laboratory results were negative and no pathogen related accident had been identified.
Pneumonic plague is the most transmissible form of plague and can spread between people. Without early antibiotic treatment, it can be fatal. Russia has recorded isolated plague cases since 2014, generally linked to exposure to infected rodents, and those outbreaks have been contained.
For now, the confirmed picture is narrower than the speculation: the Russian government says plague was not detected, while precautionary restrictions remain unusually extensive.
Facts that do not bend.
