PLAGUE SCARE IN RUSSIA: U.S. Demands Answers After 28-Year-Old Lab Worker Dies and Nearly 200 Are Placed Under Observation
The Trump administration is closely monitoring a potentially serious public-health incident in Russia after a 28-year-old employee of a Siberian anti-plague research institute died following a suspected case of pneumonic plague, prompting quarantine measures and medical monitoring of nearly 200 people who may have come into contact with her.
The State Department confirmed Sunday that U.S. officials are tracking developments in Russia’s Irkutsk Oblast together with the Centers for Disease Control and Prevention and other federal agencies. Washington is also pressing Moscow to disclose what happened as conflicting accounts emerge about the woman’s illness and Russian authorities stop short of confirming that she died from plague.
“We are aware of reports of a fatal case of suspected pneumonic plague in Irkutsk Oblast, Russia,” a State Department spokesperson said. “We are monitoring the situation closely with the CDC and our other interagency partners.”
The State Department called on “Russian authorities to share accurate information quickly and openly,” while emphasizing that many of the circumstances surrounding the case remain unconfirmed.
At the center of the mystery is Darya Shipilova, 28, an employee of the Irkutsk Research Anti-Plague Institute, an institution that works with dangerous infectious diseases, including the bacterium that causes plague.
According to Russian independent media reports, Shipilova may have been exposed on September 25 while working with live plague bacteria when a test tube containing the pathogen was accidentally broken. That account has circulated widely but has not been officially confirmed by Russian health authorities.
Shipilova subsequently became seriously ill and was admitted to a hospital in Shelekhov, outside Irkutsk, on September 29. She reportedly developed severe pneumonia-like symptoms and was placed on a ventilator before dying in intensive care in the early hours of October 2.
The case immediately triggered extraordinary precautions. The inpatient section of the Shelekhov district hospital was placed under quarantine, and people who had been in contact with Shipilova were identified and placed under medical observation.
Russian media reports put the number of people being monitored at approximately 189. According to one breakdown, 114 were being observed at one hospital, 63 at another facility and 12 at the anti-plague institute where Shipilova worked.
So far, Russian officials say the people being monitored have shown no signs of illness and have tested negative.
The Russian government’s response nevertheless indicates the seriousness with which authorities are treating the incident. Anna Popova, Russia’s chief sanitary official and head of the federal public-health agency Rospotrebnadzor, traveled more than 2,600 miles from Moscow to Irkutsk to oversee the response.
Irkutsk Governor Igor Kobzev convened a special meeting of the regional commission responsible for sanitary and epidemic prevention measures after authorities received information concerning what he described only as a suspected case of a “particularly dangerous infection.”
Kobzev did not identify the disease as plague, saying instead that authorities were carrying out a full range of epidemic-control measures and that those who had been in contact with the patient were under observation.
The head of neighboring Buryatia, Alexey Tsydenov, initially appeared to provide a more direct confirmation. He said Shipilova had died of plague while stressing that she had not traveled to Buryatia and that there was no outbreak there. His statement was subsequently edited to say that she “may have died from plague.”
Russia’s public-health authorities have since pushed back against reports that Shipilova’s death was caused by the plague bacterium. Rospotrebnadzor said Sunday that she had been diagnosed with pneumonia of unknown origin and that testing had not identified microorganisms connected to her professional work. The agency said the epidemiological situation in the region remained stable.
That leaves a major unanswered question: whether the extensive quarantine and contact-tracing operation was undertaken because Shipilova actually contracted pneumonic plague, because authorities initially feared that she had, or simply as an extreme precaution because of her work with dangerous pathogens.
Reports of the possible laboratory accident have also been questioned by some specialists. Epidemiologist Mikhail Favorov expressed skepticism that merely breaking a test tube would have produced the reported infection because employees working with live plague bacteria should be wearing specialized protective equipment.
The conflicting accounts are one reason Washington is seeking greater transparency from Moscow.
Former CIA officer Dan Hoffman said American intelligence agencies would likely be gathering information from numerous sources in an attempt to establish what actually happened.
“I would also expect our embassy in Moscow to be engaging with their diplomatic counterparts at an official level because we might have people in Russia who might be at risk,” Hoffman said.
“Washington will be speaking to all of our allies and partners in the region and sharing what we know.”
Despite its fearsome historical reputation, plague is no longer automatically a death sentence. The disease is caused by the bacterium Yersinia pestis and still occurs naturally in several parts of the world, generally circulating among rodents and fleas.
There are three principal forms of the illness: bubonic, septicemic and pneumonic plague. Pneumonic plague is the form involving the lungs and is considered particularly dangerous because, unlike ordinary bubonic plague, it can spread from person to person through respiratory droplets when there is close contact with an infected individual.
Untreated pneumonic plague can progress extraordinarily rapidly and can be fatal. Modern antibiotics, however, are highly effective when treatment begins early, with health authorities stressing that patients should receive treatment as soon as plague is suspected rather than waiting for final laboratory confirmation.
The State Department similarly emphasized that pneumonic plague “is treatable with common antibiotics, especially when treatment starts early.”
The World Health Organization says pneumonic plague can become fatal within 18 to 24 hours after the onset of symptoms if it goes untreated, but patients have a high chance of recovery when the disease is identified promptly and appropriate antibiotics are administered.
The current incident therefore does not by itself indicate that Russia is facing a widespread plague outbreak. As of Sunday, there were no confirmed reports of secondary infections among the nearly 200 people reportedly placed under observation, and Russian authorities maintain that the regional epidemiological situation is stable.
The secrecy and conflicting information surrounding Shipilova’s death, however, have attracted attention outside Russia, particularly because she worked at an institute specifically responsible for researching plague and other highly dangerous infectious diseases.
Russia has long maintained specialized anti-plague institutes because natural reservoirs of Yersinia pestis exist in parts of the country and neighboring regions. Workers who handle live cultures of the organism are among those for whom Russia recommends plague vaccination.
Russia’s previous publicly reported human plague case occurred in 2016, when a 10-year-old boy in the Altai Republic contracted the disease. Plague continues to occur naturally elsewhere in the world, with cases recorded particularly in parts of Africa.
For Americans, the State Department said there has been no change to its broader warning against travel to Russia, which is already classified at Level 4, “Do Not Travel,” for reasons unrelated to the suspected plague case. Americans who nevertheless travel abroad are being encouraged to enroll in the department’s Smart Traveler Enrollment Program to receive security and emergency information.
For now, the key questions remain unresolved: what caused Shipilova’s fatal illness, whether she was exposed to Yersinia pestis while working at the Irkutsk institute, and whether anyone who came into contact with her was infected.
