Residents of Shelekhov, where 28-year-old Daria Shipilova died in hospital overnight on October 2, say people in protective suits have appeared on the streets, while masks are reportedly being handed out even in kindergartens.

Because pneumonic plague can spread from person to person, strict anti-epidemic measures have now been introduced around the city.

There is growing alarm in Irkutsk as well: authorities and security officials held an emergency meeting, Rospotrebnadzor chief Anna Popova arrived in the region, and a city cleanup event was postponed.

Meanwhile, one Irkutsk resident posted a video putting on a plague doctor mask with the caption: “Ready for a trip to the store.”</p>&mdash; NEXTA (@nexta_tv) <a href="https://x.com/nexta_tv/status/2106293182044704946?ref_src=twsrc%5Etfw">October 3, 2026</a></blockquote>

<h2>Russia downplays plague rumours</h2><p>Russia's federal public health agency and consumer protection watchdog said that lab worker was diagnosed with “pneumonia of unknown etiology." It added that laboratory analysis of material from the patient did not reveal any microorganisms associated with her work handling dangerous pathogens. Additionally, the institute’s special commission and Rospotrebnadzor concluded that no emergency or security breach had occurred and no other infectious disease complaints had been registered among institute employees over the preceding 10 days. Alexei Tsydenov, head of the neighboring republic of Buryatia, initially claimed the employee had died of the plague, before modifying his statement with the word “maybe.” Rospotrebnadzor said all close contacts were placed under medical observation with daily laboratory testing, which detected two cases of Covid-19 and two cases of rhinovirus, but no other infections. Irkutsk region Governor Igor Kobzev said in a video published Monday that family members and close relatives under quarantine could be discharged next week. The Kremlin referred all questions about the issue to Rospotrebnadzor.</p>

A suspected pneumonic plague case in Russia’s Siberia has triggered a mask mandate, hospital quarantine and other precautionary measures. Nearly 200 people are under medical observation after a 28-year-old lab worker died, while neighbouring countries have stepped up border health surveillance.
