World Health Agency Asks Russia About Second Sick Irkutsk Lab Worker

WHO, the U.N. health agency, asked Russia for details about media reports of a second Irkutsk lab worker with pneumonia, a lung illness. It follows the death of Darya Shipilova, 28, of the Irkutsk Anti-Plague Research Institute. Russian officials said she died of pneumonia from unknown cause and say they properly informed WHO. Clear test results will shape outside trust.
