Quarantine Measures

The publication 'Lyudi Baykala' reported on October 4 that a three-week quarantine was introduced in several hospitals in Irkutsk. According to journalists, clinical hospitals No. 1, No. 3, No. 10 and the Ivano-Matreninskaya children's hospital were closed. One family expecting a child told the publication that a maternity hospital in Irkutsk was also under quarantine. A source in the healthcare sector said Irkutsk doctors are already openly talking about plague, but the diagnosis is not recorded in hospital documents. The source added that selective quarantine is not applied when pneumonic plague spreads; restrictions are introduced in all medical institutions simultaneously.

Official Response

Shortly after the report, Rospotrebnadzor issued a statement declaring the sanitary-epidemiological situation in Irkutsk Oblast, Irkutsk and Shelekhov stable. The agency reported that a special set of measures had been organized and carried out. These measures were prompted by the illness of an employee of the Irkutsk Anti-Plague Institute with 'pneumonia of unknown etiology'. Rospotrebnadzor specifically noted that no microorganisms related to her professional activity were found in the deceased woman's body. On October 3, a mask regime was introduced at the Irkutsk Aluminum Plant in Shelekhov; plant director Artyom Fomin called it a preventive measure.

Death Investigation

Darya Shipilova, 28, died in a hospital in Shelekhov, a satellite city of Irkutsk, a few days earlier. Journalists established that she worked as a laboratory assistant at the Anti-Plague Institute. She was brought to the hospital on September 29 and died two days later. Media reported two versions: Shipilova was hospitalized with pneumonic plague after returning from Thailand, or she accidentally broke a test tube containing plague pathogen. Rospotrebnadzor stated that no emergency involving pathogenic microorganisms occurred at the institute.
