# US-Russia diplomatic response to Siberian health concerns > Live situation record from CLSTR: https://clstr.news/situations/us-russia-diplomatic-response-to-siberian-health-concerns > Updated: 2026-10-07T18:25:19.000Z. Sources: 31. Developments: 2. A potential health crisis in Russia’s Irkutsk region has prompted diplomatic engagement between U.S. President Donald Trump and Russian President Vladimir Putin. The situation follows the death of a 28-year-old scientist at the Institute for Fighting Plague Diseases in Siberia. While social media reports suggested the death was caused by pulmonary plague, Russian health authorities, specifically Rospotrebnadzor, stated the cause was “pneumonia of undetermined cause.” The World Health Organization has requested information from Russia to investigate the possibility of a second case in the region. In response to the reports, Governor Igor Kobzev convened an emergency health commission. President Trump has indicated that a telephone conversation with President Putin is expected to discuss the matter. During a White House press conference, Trump stated that the United States does not believe the suspected outbreak is the result of a “biological weapon,” noting, “We don't think so,” though he added that the full truth would be known soon. He also noted that Russian authorities have claimed the situation is under control. A diplomatic disagreement has emerged regarding the timing of this contact. While President Trump announced that a call was organized, noting it coincides with Putin's birthday, Kremlin spokesperson Dmitry Peskow stated that no specific time has been agreed upon and the two leaders have not yet coordinated the conversation. International observers and the WHO continue to call for greater transparency from Russian officials to conduct a proper risk assessment. ## Claims - The Kremlin has not yet agreed on a specific time for a telephone conversation between Vladimir Putin and Donald Trump.
