WHO asks Russia for details on plague institute worker's death

The World Health Organization has asked Russia for more details about the death of a plague institute worker in Siberia, stressing that transparency is essential for assessing potential health risks. The 28-year-old laboratory worker, Darya Shipilova, died Friday from pneumonia of unknown origin, prompting international concern and the quarantine of around 200 people. Russia reports no plague cases among her contacts, with 60% of quarantined individuals released. WHO Director General Tedros Adhanom Ghebreyesus cited conflicting reports, including media claims of a second employee with pneumonia, which Reuters could not verify. His request echoes US Secretary of State Marco Rubio's call for more information from Moscow.
