U.S. Secretary of State Marco Rubio, during his travels to Iceland, Greece, and Portugal, stated that the government is keenly observing a situation in Russia. Reports surfaced of a lab worker potentially infected with the plague. This follows an incident involving a 28-year-old employee at a Siberian plague research center.
Russian authorities took swift actions, placing a hospital under quarantine and monitoring many individuals after the death of the worker from unexplained pneumonia. Although concerns persist about pneumonic plague, they remain unverified. The worker, Darya Shipilova, was part of the Irkutsk Anti-Plague Research Institute in Siberia.
Testing did not reveal any infection by workplace-related pathogens, leaving the cause of her illness unidentified. Despite this, measures taken suggest significant concern within Russia and abroad. On October 5, Reuters reported that all contacts had been monitored, with no new cases identified among the institute’s employees.
Secretary Rubio emphasized that while the situation needs attention, there is no immediate cause for alarm. His comments align with a recent State Department statement noting that agencies, including the CDC, are tracking events.
“It’s crucial to keep an eye on developments, especially with limited travel between Russia and the U.S. If something spreads, it could do so rapidly,” Rubio commented.
East2West news agency reported over 60 institute employees and nearly 200 others connected to Shipilova remained under observation. However, these figures await official confirmation. Neighboring countries, such as Kyrgyzstan and Uzbekistan, have heightened border health checks.
The Irkutsk region hospital where Shipilova was treated has halted operations temporarily. Irkutsk Governor Igor Kobzev labeled the case a suspected “particularly dangerous infection.” Following these developments, Anna Popova from Russia’s public health body Rospotrebnadzor conducted a meeting in Irkutsk. An aluminum plant in proximity also mandated masks for workers.
Kremlin spokesman Dmitry Peskov advised reliance on official data, dismissing rumors. According to Rospotrebnadzor, Shipilova had pneumonia of unknown origin, with no link to her professional activities identified by tests. No lab incidents with microorganisms were noted.
Pneumonic plague, caused by Yersinia pestis, can spread through droplets between people but is treatable with early antibiotics. Russian officials claim stability in the epidemiological scenario, with no evidence of a plague outbreak. Despite extensive containment actions, the cause of Shipilova’s pneumonia remains unclear.
