According to US officials, the Trump administration is preparing to send an official diplomatic note to Russia requesting more details about the deaths associated with a pneumonic plague research facility in Siberia, as well as information on various quarantine measures that have been implemented since then. This proposed request comes at a time when the US is increasingly dissatisfied with Russia's lack of details. Earlier, the Russian public health agency reported that a laboratory employee at a research institute in the Irkutsk region that specializes in plague died after being diagnosed with pneumonia of “unknown” cause. Officials said the official message from the US — known in diplomatic jargon as a “diplomatic note” — was intended to remind Russia that it is obligated to share information on disease outbreaks with other governments in a timely manner under international law. The officials requested anonymity in order to discuss sensitive foreign affairs.
