Russia plague scare: 28-year-old researcher dies of 'unknown' infection after test tube accident

Moscow: A 28-year-old female laboratory diagnostics specialist at the Irkutsk Anti-Plague Institute in Siberia died under quarantine following a suspected accidental exposure to live bacterial samples. According to reports by regional outlets and regional disclosures, the researcher, identified as Daria Shipilova, reportedly suffered an accidental breakage involving a test tube containing live Yersinia pestis while processing biomaterial samples. She was admitted to the Shelekhov District Hospital near Irkutsk, presenting with severe pneumonia symptoms, placed on a ventilator, and passed away shortly after admission.

Quarantine Measures and Regional Confirmations

While federal health watchdog Rospotrebnadzor initially characterised the incident publicly through cautious statements regarding an unspecified "particularly dangerous infection", regional leaders openly confirmed the nature of the pathogen. As reported by The Moscow Times, Alexey Tsydenov, the head of the neighbouring republic of Buryatia, publicly identified the cause of death as a form of plague. In response to the fatality, health authorities enforced a strict quarantine at the Shelekhov District Hospital, suspending standard admissions and discharges while specialised security and medical teams deployed containment protocols.

Mass Medical Surveillance and Investigation

Public health officials initiated wide-scale contact tracing to prevent secondary transmission, placing nearly 200 individuals under medical observation across multiple facilities in the region. According to updates provided by Irkutsk region Governor Igor Kobzev via Telegram, monitored contacts, including hospital staff and community members, have tested negative so far and exhibited no clinical symptoms of illness. Meanwhile, authorities have formally launched a criminal probe into potential violations of sanitary and epidemiological rules resulting in death, focusing on biosafety compliance inside the specialised research facility.
