Death of Russian Scientist Raises Health Concerns

The death of Darya Shipilova, a 28-year-old employee at the Irkutsk Anti-Plague Institute in Russia, has sparked public health concerns about a potential outbreak of the disease she researched. Russian authorities have placed those who had contact with her under medical supervision, as reported by the World Health Organization (WHO). U.S. officials have called for greater transparency from Moscow, demanding answers amid reports of hospital quarantines. Newsweek reached out to Russia’s health watchdog, Rospotrebnadzor, for comments.

Has the Plague Actually Been Confirmed?

Shipilova’s death has led to speculation regarding her work at the research institute focused on dangerous infections. The WHO identifies three main forms of plague infection: bubonic, pneumonic, and septicemic. Pneumonic plague, caused by the bacterium Yersinia pestis, found in small mammals and fleas, was a considered cause of her death. However, Rospotrebnadzor stated that Shipilova died from “pneumonia of unknown etiology,” adding that tests detected no microorganisms related to her work. Laboratory evidence confirming Y. pestis as the cause was not available, indicating the official stance does not confirm the plague.

The WHO was informed by Russian authorities that the illness initially appeared as a typical acute respiratory viral infection and confirmed no plague cases in Irkutsk. The WHO continues to seek more information from Russia about the pneumonia-linked pathogen and remains vigilant, ready to support if requested.

What Did Laboratory Tests Show?

According to WHO, Russian health officials conveyed that no plague cases are confirmed in Irkutsk, and Shipilova’s illness began as a respiratory viral infection. Irkutsk’s governor, Igor Kobsev, confirmed no microorganisms connected to her professional duties were found in her body. Despite this, detailed test results remain undisclosed. The lack of information has led to questions, Tsarina Weschler, editor at Plague News, notes. “She worked at a plague institute, where plague tests can be completed rapidly. Four days post-mortem, the official cause is still ‘unknown origin,’ and no alternative cause is mentioned,” Weschler told Newsweek.

Did a Laboratory Accident Actually Occur?

Reports claim Shipilova accidentally broke a test tube containing the plague pathogen on September 25 at work, which was not reported immediately. Rospotrebnadzor later refuted this, with a commission finding no incidents involving pathogenic microorganisms at the institute. Siberia Realities, an outlet affiliated with the U.S.-funded Radio Free Europe, shared former colleagues’ anger over the claims that Shipilova violated safety protocols. A former classmate, Valentina, affirmed the lab’s strict regulations, labeling accusations against Shipilova as shocking. Javier Pizarro-Cerda from Institut Pasteur stated that workers handle plague wearing protective gear, indicating potential accidents would not easily lead to exposure.

What Explains the Conflicting Accounts?

Kremlin-controlled Russian media has offered differing official accounts compared to independent sources. Kremlin spokesman Dmitry Peskov urged focus on Rospotrebnadzor’s official statements over “various rumors.” Alexei Tsydenov, head of Buryatia, initially claimed a possible plague death but later altered his statement, causing confusion. An independent Telegram channel, People of Baikal, suggested doctors openly discussed the plague hypothesis. Russian state TV, under the defense ministry channel Zvezda, mentioned the plague only once.

Internet Archive’s TV News Archive data shared with Newsweek showed the channel reported an emergency Rospotrebnadzor meeting. The presenter explained this followed local reports about a patient dead from the plague. However, Internet Archive noted this was the only broadcast. Rospotrebnadzor website statements confirmed meetings over a suspected dangerous infection, yet the published diagnosis remained “pneumonia of unknown origin,” according to Tilly Doser from Plague News.

Why Have Hospitals Been Quarantined?

The U.S. State Department noted that the plague is treatable with antibiotics, especially if treatment begins promptly. Rumors of limited hospital access in Irkutsk due to quarantine remain unverified by officials, leaving the threat’s nature and response unclear. People of Baikal claimed three city hospitals, a children’s, and a maternity hospital entered quarantine, with up to 200 individuals under observation. An expectant mother told the outlet she was screened for plague symptoms at the Irkutsk Prenatal Center days before delivery. Blogger Ulyana Gavryunina reported limited access to the maternity hospital due to quarantine.
