Short answer
Several possible studiesNo clear answer.
More than one paper fits the article's details, and none fits well enough to single out. Checking claims against the wrong study would be worse than not checking them at all.
Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim 1 of 8Not checkedThe death of a worker at Russia's Irkutsk Anti-Plague Research Institute has prompted speculation about a laboratory accident involving the bacterium that causes plague, but Russian authorities described her illness as pneumonia of unknown cause and denied a connection to pathogens handled at work.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 2 of 8Not checkedNeither plague as the cause of death nor the alleged laboratory accident has been independently established in the publicly available evidence.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 3 of 8Not checkedBrendan Wren says pneumonic plague can be rapid and fatal, with the article noting it can kill within 24 hours if untreated.View evidenceHide evidence
As statedwithin 24 hours
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 4 of 8Not checkedZania Stamataki says a tube breakage in a high-containment lab is an incident, not necessarily an exposure, because multiple barriers such as biosafety cabinets, sealed secondary containers, negative-pressure rooms, training, procedures, and protective clothing are designed to prevent release.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 5 of 8Not checkedThe article says investigators would need to determine where any incident occurred, what the container held, whether the material was infectious, and whether it could have generated inhalable particles, as well as review cabinet, ventilation, maintenance, and procedure records.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 6 of 8Not checkedStamataki says sequencing the organism from the worker and comparing it with strains held at the laboratory would be needed to establish a genomic link; without that, there is only coincidence in time rather than a demonstrated causal chain.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 7 of 8Not checkedThe article notes that monitoring about 200 contacts is a precautionary protocol and should not be interpreted as an estimate of how many people are infected.View evidenceHide evidence
As statedapproximately 200 contacts
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 8 of 8Not checkedThe article uses the 1979 Sverdlovsk anthrax outbreak as historical context for why laboratory ventilation failures attract attention, citing a 1994 Science investigation and a 2016 mBio paper, but says that episode involves a different pathogen, facility, and setting and does not provide evidence about Irkutsk.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Method layer
No single source study was found.
NewsLink still surfaces nearby research so you can inspect the field instead of a single paper.
