U.S., WHO seek details from Russia after Siberian lab worker’s death

The United States has sent a formal diplomatic complaint to Russia demanding more information about the death of a 28-year-old technician at an anti-plague research institute in Siberia, amid conflicting reports about her illness and quarantine measures imposed afterward.

Darya Shipilova, who worked at the Irkutsk Anti-Plague Research Institute of Siberia and the Far East, died Oct. 2 after becoming ill. Unconfirmed reports linked her death to pneumonic plague and a possible laboratory accident, but Russian health authorities said she died from pneumonia of undetermined cause and denied that her illness was connected to her workplace.

Russian officials temporarily restricted access to the institute and several hospitals while monitoring about 200 close contacts. Russia’s health watchdog said no additional cases had been identified. Irkutsk Governor Igor Kobzev said Thursday that quarantine measures and monitoring had ended, describing Shipilova’s illness as community-acquired pneumonia.

The World Health Organization said it lacked enough information to conduct a full risk assessment. Director-General Tedros Adhanom Ghebreyesus called for timely and transparent reporting and said the agency had asked Russia to clarify reports of another employee with pneumonia of unknown cause. The WHO has assessed the international risk as very low.

The U.S. Embassy in Moscow issued a health alert advising Americans in the area to follow local guidance and avoid affected facilities. The State Department’s existing Level 4 “Do Not Travel” advisory for Russia remains in effect. President Donald Trump said he planned to raise the case with Russian President Vladimir Putin and offered U.S. assistance, while the Kremlin said no call had yet been arranged.

WHAT THE EDITOR DID

The second model checked the writer's draft against the same sources and changed it before publication. Struck words were in the draft; underlined words are its corrections.

WHAT IT FLAGGED editor revise: Two details should be tightened to match the sourced wording. - "The United States has formally requested more information from Russia": The Hill reports the U.S. sent a formal diplomatic complaint demanding more information; the phrasing as a formal request is imprecise and should be corrected to match the source. - "The World Health Organization said it lacked enough information to complete a risk assessment.": The source says WHO was not able to conduct a full risk assessment, not that it could not complete one.
