WHO and U.S. officials seek answers about Russian lab worker’s death
The cause of the lab worker’s death remains unconfirmed, and WHO assessed the risk as low for Russia and very low for Europe.

The World Health Organization has asked Russia for more information about the death of a 28-year-old worker at a plague research institute in Irkutsk. U.S. officials have also pressed Moscow for details. The cause of her illness has not been confirmed. Russian authorities said she died of pneumonia of unknown cause and that tests found no microorganisms linked to her work.
WHO spokesman Christian Lindmeier said Russian authorities had identified the worker’s contacts and none had symptoms associated with plague. WHO assessed the risk as moderate to low in Irkutsk, low for Russia overall and very low for the WHO European region. Reports of a second employee with pneumonia of undetermined cause were among the issues WHO said it wanted clarified.
U.S. Secretary of State Marco Rubio called on Russia to share more information. The State Department said it had officially requested additional information from the Russian government.
