Darya Shipilova is said to have been exposed to the pathogen while working at the Irkutsk Anti-Plague Research Institute in Siberia
Hundreds of people have been placed into quarantine in Siberia after a laboratory worker died of suspected plague, according to reports.
Darya Shipilova, an employee at the Anti-Plague Research Institute in Shelekhov, was exposed to the bacteria after she accidentally broke a test tube containing the pathogen while she was collecting samples, the Kyiv Independent reported.
She was hospitalised on 29 September with severe pneumonia of "unknown origin” and placed on a ventilator, but died shortly after.
Independent Russian outlet Lyudi Baikal reported that several hospitals in the city of Irkutsk had closed for a three-week quarantine.



How do someone test a virus that is “unknown”…?
It’s not a virus, and it’s not unknown.
its the pneumonic plague, so not a virus, but Yersinia pestis, aka the black death.
Speculation only, no one other than the lab know what that virus are, it could be just that, or it could be something else entirely that they made to test vaccine or some other test(which is very normal procedure iirc)
*Pathogen, we do not know if it’s a virus or a bacteria
The test is also unknown.
