Black Death Plague Outbreak: Nearly Two Hundred People Under Observation After Russian Lab Worker Dies

Around 200 people were reportedly placed under medical observation in Russia after a laboratory worker died following an alleged accident involving plague bacteria at an institute in Irkutsk on 25 September.

The worker, 28-year-old Darya Shipilova, reportedly broke a test tube containing live Yersinia pestis while handling samples at the Irkutsk Anti-Plague Institute. Independent news outlet Baikal People reported the incident and subsequent hospital quarantine measures across the surrounding region.

Five Hospitals Quarantined Amid Plague Concerns

Five medical facilities in Siberia reportedly closed for a minimum quarantine period of three weeks after Shipilova's death. The number of affected hospitals was reported to have risen from one to five as the quarantine measures extended across the region.

The facilities identified include City Clinical Hospitals Nos. 1, 3 and 10, as well as the Ivano-Matreninskaya City Children's Clinical Hospital. A fifth facility is not identified in the reporting, leaving the full list of affected hospitals unclear.

The figure of around 200 people relates to medical observation rather than confirmed infections. It remains unclear how many had contact with Shipilova or the laboratory samples, and whether any have tested positive for plague.

Citing a healthcare source, Baikal People reported that physicians in Irkutsk were 'already openly talking about the plague.' The comment conveys the concern described within the local healthcare sector, although it offers no details about diagnoses among the people being monitored.

Regional Leader Cited in Plague Death Report

The Moscow Times reported that Alexei Tsydenov, head of the neighbouring republic of Buryatia, confirmed that Shipilova had died from an unspecified form of plague.

His reported confirmation concerned the cause of Shipilova's death. It did not identify the form of the disease involved or establish whether she had pneumonic plague, which was mentioned in the wider reporting.

The alleged accident occurred during her work with laboratory samples, with the broken test tube reported to contain live bacteria. Although the incident was dated to 25 September, the timing of her death and the length of her illness remain unclear.

Yersinia pestis causes plague, a serious infectious disease primarily found in small mammals and their fleas. In this case, the alleged point of exposure was a workplace handling the live bacterium.

The reports describe a death linked to a laboratory incident and several precautionary measures. They do not establish a wider outbreak or transmission beyond Russia, despite concerns about the possibility of the disease spreading to other European countries.

Plague Precautions Extend Beyond Medical Facilities

A mask mandate was reportedly introduced at a major aluminium plant in Irkutsk. The reported requirement extended precautions to an industrial workplace outside the hospitals placed in quarantine, although no infections among plant employees were specified.

Several US politicians also reportedly advocated a suspension of commercial air travel to and from Russia until the situation becomes clearer. The calls concern a proposed restriction, rather than a confirmed decision to halt flights.

Those calls sought restrictions on flights in both directions while further information was awaited. The politicians were not named in the reports, and no formal proposal or action by aviation authorities was identified.

Ambulances transporting people for testing were also allegedly accompanied by officers of the FSB, Russia's federal security service. The reports do not explain the reason for their alleged involvement or identify who authorised the escorts.
