A senior official from the United Nations health agency is calling for more information from Russia regarding the mysterious death of a lab worker in Siberia amid concerns of a possible plague infection. The 28-year-old woman, identified as Darya Shipilova in Russian media, passed away on October 2 under unclear circumstances, sparking speculation about pneumonic plague and her work with pathogens at the Irkutsk Anti-Plague Research Institute in Siberia and the Far East.
Maria Van Kerkhove, the director of epidemic and pandemic management at the World Health Organization (WHO), stated during a news briefing in Geneva that the cause of the woman’s death remains unknown, emphasizing the need for additional details. The WHO is also investigating unconfirmed reports of a second case of pneumonia with an uncertain cause linked to the same lab in southeastern Siberia.
Dr. Tedros Adhanom Ghebreyesus, the WHO director-general, mentioned that the agency is attempting to verify the validity of the reports but has not been able to confirm them yet. Meanwhile, Russia’s public health watchdog, Rospotrebnadzor, has stated that extensive testing did not find any evidence linking the lab worker’s illness to the pathogens she was exposed to, dismissing any connection to pneumonic plague.
Contrary to the speculation, Russia has officially reported the woman’s cause of death as pneumonia, a common respiratory infection. Health authorities in Russia have not detected any recent cases of plague, with monitoring revealing cases of COVID-19 and rhinovirus among the 200 individuals under observation since the incident.
Pneumonic plague, a severe and contagious form of the disease caused by the Yersinia pestis bacterium, is less frequent but can lead to serious health complications. The region of Siberia has a history of plague outbreaks, including the first known prehistoric human incident of the disease.
Russian officials have denied the presence of plague cases in the Irkutsk region and have implemented preventive measures, such as contact tracing and medical monitoring, following the lab worker’s death. The WHO has requested more information to clarify the circumstances surrounding the severe pneumonia and the reported second case.
Shipilova’s mother, a former doctor, described her daughter as dedicated and hard-working but has not received official documentation detailing the cause of death. The hospital where Shipilova passed away has been quarantined, restricting patient admissions and discharges while continuing outpatient services.
Despite international interest in the case, Russian authorities have maintained a tight grip on information, avoiding discussions about the potential plague link. Speculation and coverage of the incident have been limited on state-controlled media, with some outlets retracting previous reports.
Experts have highlighted the importance of transparency in such situations, emphasizing the potential harm of concealing information. The lack of clarity surrounding the case has raised concerns about the public’s trust in official narratives and the handling of health crises in Russia.
