WHO: No further infections reported at Russian plague lab in Siberia

The World Health Organization reported Monday no further infections at a Russian plague lab in Siberia, following a researcher's reported death from pneumonic plague, with public health risk to the general population assessed as low. Russian authorities confirmed no disease cases in Irkutsk, and all patient contacts are monitored with none showing symptoms, though early test results are negative but unclear for which pathogens. The WHO has not received formal notification under International Health Regulations, as Russia may still be determining if the event is notifiable. Secretary of State Marco Rubio said Tuesday it is incumbent on Russia to share more information, while the Trump administration monitors the case with the CDC. The researcher's cause of death remains unconfirmed, and plague occurs naturally in wild animals in the region.
