Health authorities worldwide are still awaiting answers almost a fortnight after a 28-year-old investigator succumbed to an unexplained illness while on duty at a Russian plague research laboratory. Initial reports indicated that Darya Shipilova, an employee at the Irkutsk Anti-Plague Research Institute, had contracted pneumonic plague, which sparked anxiety concerning the nature of the studies performed there and the protocols utilized.
Moscow officials have subsequently ruled out pneumonic plague—a bacterial condition stemming from the same microorganism responsible for the more familiar bubonic plague—as the cause of Shipilova’s death, yet they have not yet verified the specific pathogen that triggered her pneumonia. The event, which provoked criticism from Washington and other foreign administrations, has brought to light the persistent international skepticism surrounding Russian medical science, a sentiment rooted in the former Soviet military’s once-extensive biological weapons initiatives.
The Legacy of the Soviet Anti-Plague System
Although the Irkutsk facility never operated as a military establishment, it formed a component of the expansive yet clandestine “Anti-Plague System”. The Soviet Union instituted numerous field stations and scientific centers during the early decades of the 20th century to curb frequent contagions in rural regions where plague-carrying wildlife like marmots, gerbils, and rats are prevalent.
Susan D. Jones, a veterinary historian at the University of Minnesota who in 2018 toured a former Soviet Anti-Plague Institute in what is now Kazakhstan, noted that the initial goal was central surveillance of vast areas, including the steppes with large populations of burrowing wild rodents. Early expeditions were rudimentary, with scientists venturing on horseback into plague hotspots to exterminate rodents, dig up burrows, and burn food supplies without effective disinfectants or personal protective equipment.
By the middle of the 20th century, the focus shifted from eradication to outbreak prevention, opening labs in cities across the USSR. As an antibiotic to treat plague was developed, thousands of year-round employees staffed these facilities, supported by hundreds more hired seasonally to collect samples in the field.
Secrecy and Infrastructure Challenges
Research inside these Soviet-era facilities was “hidden behind a curtain of secrecy”, according to a 1994 essay by a former anti-plague researcher, Moisey Iosifovich Levi. Workers were instructed never to mention specific details about their work to avoid links with military bioweapon programs, and buildings were constructed to resemble normal housing units.
Sonia Ben Ouagrham-Gormley, a biodefence researcher at George Mason University who has visited many anti-plague institutes in former Soviet states, noted that biosafety and biosecurity differed significantly from what is in Western countries. Compilations edited by Levi bearing the name Interesting Stories of the Events and People of the Anti-Plague System of Russia and the Soviet Union outlined hazardous circumstances, such as animal infections, laboratory blazes, and missing microbial specimens. While some facilities received upgraded equipment toward the end of the Soviet era, smaller and more remote locations like the Irkutsk institute struggled to keep pace.
Igor Valerianovich Domaradsky, a former director of the institute, wrote in an essay included in Levi’s anthologies that the Irkutsk facility failed to receive adequate attention, causing it to lag significantly in acquiring new equipment and technology.
Modern Containment and Ongoing Questions
Following the fall of the Soviet Union, most labs remained open and largely unchanged for decades. When Ben Ouagrham-Gormley toured upwards of a hundred legacy Soviet facilities during the early 2000s alongside researchers from the James Martin Center for Nonproliferation Studies, inventory and tracking relied on manual paper records, and refrigerators were secured with wax seals.
Over the next two decades, several facilities in former Soviet states were refurbished or rebuilt, creating state-of-the-art centres with strict levels of containment and full personal protective equipment. Due to the fact that Moscow has barred foreign scientists and government inspectors from its Anti-Plague System sites, determining whether conditions at these domestic facilities have truly advanced remains challenging.
Ben Ouagrham-Gormley noted an assumption that Russian facilities have not improved much, though they likely maintained traditional Soviet procedures designed to prevent accidents despite equipment shortages. Russian authorities remain adamant that Shipilova’s death was not the result of unfollowed protocols or lapses in biosecurity at the Irkutsk facility.
