WHO report on Russian lab worker death highlights "key uncertainty"

What happened

Over the weekend, the World Health Organization released a disease outbreak report on the events surrounding the death of a Russian infectious disease researcher earlier this month, highlighting that Russia has yet to report a confirmed cause of death. Without a cause of death, it's unclear if Russia's precautions were the right ones. With that "key uncertainty," the United Nations health agency said it remains impossible to assess the risk of the event or whether the public health measures Russia took were adequate to prevent spread of the unknown disease.
