These reports stated that Russia's state health regulator had informed the WHO that no plague case had been registered. They also noted that the cause of death remained unknown and that approximately 200 people were quarantined. ### Right - Right-rated reports focused on the World Health Organization's statement that Russia confirmed the death of a lab worker at a plague research facility in Siberia, while also stating that no plague case was registered. These reports included details that the worker died on October 2, approximately 200 people were quarantined, and the cause of death was unknown. The Star Kuala Lumpur, a right-rated outlet, also noted the death occurred in undisclosed circumstances. **Provisional coverage gap:** left.
