The United States has formally complained to Russia about its handling of a reported death at an anti-plague institute in Siberia, urging greater transparency. The complaint, known as a démarche, was issued shortly before President Donald Trump planned to speak with Russian President Vladimir Putin. Russian authorities have claimed the case involved pneumonia of unknown cause and denied any connection to the deceased lab worker's work at the Irkutsk Anti-Plague Institute, while dismissing media reports as false. The U.S. State Department has expressed concern over these responses and offered assistance.

Story summary
A 28-year-old lab technician named Darya Shipilova died of pneumonic plague in Siberia after breaking a test tube containing live bacteria at the Irkutsk Anti-Plague Institute on September 29, leading to her hospitalization and subsequent death two days later. Around 200 people who had contact with Shipilova were placed under quarantine, and three hospitals in the region implemented strict security measures. Governor Igor Kobzev declared a mask mandate and quarantined several facilities, including local hospitals and an aluminum plant. Russia's Chief State Sanitary Doctor Anna Popova rushed to the area to oversee the situation. The incident has raised international concern, with U.S. officials monitoring developments closely alongside the CDC and other federal agencies. Despite fears of a broader outbreak, Russian authorities maintain that the situation remains stable. Former Rospotrebnadzor head Gennady Onishchenko suggested widespread transmission is unlikely due to seasonal conditions. The incident has drawn comparisons to the initial stages of the COVID-19 pandemic in Wuhan, China, sparking concerns over transparency and information sharing.
