Quick Summary

Dr. Ken Alibek, formerly second-in-command of the Soviet Union’s secret bioweapons program, warns of potential dangers related to a mysterious death at a Russian plague laboratory. Darya Shipilova, a 28-year-old lab worker, died from pneumonia of unknown origin on October 2 after being hospitalized since September 29. Around 200 people are under monitoring in Russia's Irkutsk region. Alibek fears that if those monitored start dying or failing to respond to standard antibiotics, it could indicate a dangerous drug-resistant strain linked to the lab accident where Shipilova reportedly broke a test tube possibly containing plague bacteria. He also expresses concern about Russia’s continued biological weapons development and the potential for information suppression by authorities.

Story summary

A 28-year-old laboratory assistant named Darya Shipilova died in early October after reportedly breaking a test tube containing potentially dangerous pathogens at the Irkutsk Anti-Plague Research Institute in Shelekhov, Russia. Despite extensive speculation that she may have contracted pneumonic plague, Russian authorities continue to maintain that her death was due to pneumonia of unknown origin and have not identified the specific pathogen involved. At least 197 people who had close contact with Shipilova were placed under quarantine or surveillance, while international health organizations like the CDC remain vigilant but assert that the risk to other countries is minimal. The incident has sparked concerns about Russia's transparency regarding biological research and safety protocols at such facilities.

She → work → October
Russian authorities have not confirmed that she had plague. asserted
she → confirm → plague
Today, local media claimed a second person had died and it appears that national media has begun wiping its reports about the situation, raising fears of a cover-up. asserted
media → claim → up
Ken Alibek testified to Congress about Russia's bioweapons programs after he defected in 1992 Lab worker Darya Shipilova died in Siberia of pneumonia after reportedly breaking a test tube Health officials have been pictured in the Irkutsk wearing hazmat suits amid plague response Reports from independent media said Shipilova may have accidentally broken a test tube containing live plague bacteria. uncertain
Shipilova → testify → bacteria
Plague can take several forms, but its most dangerous is pneumonic plague, which infects the lungs and can spread from person to person through respiratory droplets. asserted
which → take → droplets
Alibek said he would be particularly concerned if more people being monitored in Russia's quarantine camps begin to die or fail to respond to standard antibiotics – a possible warning sign that a dangerous, drug-resistant strain could be involved. uncertain
strain → say → antibiotics
Antibiotics have kept plague largely at bay since they became widespread in the 1940s. asserted
they → keep → 1940s
But pneumonic plague remains extraordinarily dangerous when untreated. asserted
plague → remain → ?
A 2020 CDC review found that 98 percent of patients with pneumonic plague who received no antibiotics died, compared with 17 percent of those who were treated. asserted
who → find → those
The evidence suggests a drug-resistant strain could be devastating. uncertain
strain → suggest → ?
Russia's long history of secretly turning deadly diseases into weapons is another cause for concern, he said. asserted
he → turn → concern
'Russia is working on biological weapons, no doubt, otherwise they wouldn't have built such huge facilities in recent years,' Alibek said, pointing to an expansion of Russian biological facilities in recent years. asserted
Alibek → work → years
He warned that if the two deaths are connected to a laboratory accident, the Kremlin's playbook of secrecy could make it difficult for the outside world to find out what really happened. uncertain
what → warn → secrecy
'Definitely the information about that case is absolutely closed now,' he said, speaking to the Daily Mail just hours before the federal television channel REN TV deleted all five of its reports about the situation. asserted
channel → close → situation
'I'm 100 percent sure that you wouldn't get any new information except maybe some cover story about what really happened.' asserted
what → get → story
Russia's health watchdog says investigators found no evidence of an accident involving dangerous pathogens. asserted
investigators → say → pathogens
Still, authorities in Siberia have imposed extensive precautions, with hundreds of people Shipilova had come into contact with placed in quarantine and parts of the hospital where she died restricted. asserted
she → impose → hospital
Neighboring countries including Mongolia, Kyrgyzstan and Uzbekistan are tightening border health controls. asserted
countries → neighbor → controls
If it turns out the be pneumonic plague, quarantining close contacts of the infected is crucial because the infection spreads via droplets when people cough. asserted
people → turn → droplets
Anna Popova, head of Russia's health watchdog, Rospotrebnadzor, traveled to the region as officials mounted an emergency response. asserted
officials → travel → response
Rospotrebnadzor said samples taken from Shipilova did not reveal microorganisms linked to her work. asserted
samples → say → work
Officials also said no laboratory accident involving dangerous pathogens has been found. asserted
accident → say → pathogens
But some reports have claimed that five days before she fell ill, Shipilova accidentally broke a test tube containing Yersinia pestis – the bacterium that causes plague – while working at the institute. asserted
that → claim → institute
The conflicting accounts have deepened the mystery. asserted
accounts → conflict → mystery
Alibek said the Irkutsk facility sits within a much broader Soviet scientific infrastructure that had links to military research. asserted
that → say → research
During the 1970s and 1980s, he said, Soviet scientists studied natural strains of disease that could have military uses. uncertain
that → say → uses
If a pathogen appeared particularly deadly or difficult to treat, it was ultimately passed into the hands of Biopreparat, the secret organization responsible for developing the Soviet Union's biological weapons, he said. asserted
he → appear → weapons
Alibek has previously described Soviet efforts to create antibiotic-resistant versions of Yersinia pestis as a weapon. asserted
Alibek → describe → weapon
A researcher from Irkutsk Anti-Plague Institute during a field trip That history makes the current response in Irkutsk worth close attention, he said. asserted
he → make → Irkutsk
'If amongst people who are quarantining, you'll see more people dying, it can be antibiotic resistant,' Alibek told the Daily Mail. asserted
Alibek → quarantine → Mail
Though he never worked with the Shelekhov lab, he said it would doubtless have connections to the bioweapons program, and scientists there may have been modifying diseases. uncertain
scientists → work → diseases
And there is evidence that Russia has been pouring money into some of the same military-linked biological research facilities inherited from the Soviet era. asserted
Russia → be → era
The US government has assessed that Russia inherited the Soviet offensive biological weapons program and has not provided evidence that it was completely dismantled. asserted
it → assess → evidence
It has also accused Moscow of modernizing Soviet-era facilities that could support an offensive program. uncertain
