俄罗斯西伯利亚实验室工作人员死于鼠疫，美国密切监测

俄罗斯西伯利亚一处实验室的工作人员因鼠疫相关疾病身亡，引发国际关注。123根据报道，死者是西伯利亚防疫研究所的一名实验室技术员，名叫达莎，20多岁。3俄罗斯官方初步诊断为不明原因肺炎，3但美国和国际社会担忧该病例可能涉及肺鼠疫，且病原体有可能从该实验室泄露。12约200人因与死者有接触而被纳入医学观察范围。13

美国政府已对此事件作出反应。美国疾病控制与预防中心(CDC)正在监测俄罗斯可能发生的鼠疫风险，并表示已做好应对任何威胁的准备。2美国国务卿鲁比奥表示美方正密切监测此事，称这是值得关注的事情。3特朗普宣布计划与普京通电话讨论这一可能的鼠疫死亡事件。2

俄罗斯方面对疫情泄露的担忧提出异议。伊尔库茨克州长Igor Kobzev称生物安全小组检查后未发现应急情况，3俄罗斯官方也表示未在死者样本中发现相关微生物。3不过，死者最近曾访问过与蒙古接壤的布里亚特地区。3

A laboratory technician at a research facility in Siberia has died from suspected plague, prompting urgent international scrutiny of biosafety protocols and disease containment measures.3 The deceased, identified as Daria, was in her twenties and worked at a facility in Irkutsk.3 Russian authorities initially attributed the death to pneumonia of unknown origin,3 while international observers have expressed concern about possible pulmonary plague and potential laboratory containment failures.12

Approximately 200 people who had contact with the deceased are currently under medical observation.13 The U.S. State Department has intensified pressure on Russia regarding the incident, with Secretary of State Marco Rubio stating that American officials are "watching closely" and characterizing the situation as concerning.3 The U.S. Centers for Disease Control and Prevention is actively monitoring the situation and has indicated preparedness to respond to any emerging threat.2 Former President Trump announced plans to discuss the potential plague fatality with Russian President Putin.2

Russian officials have asserted that biosafety investigations uncovered no emergency conditions at the facility.3 Local authorities reported that the deceased had recently traveled to the Buryatia region, which borders Mongolia.3 Pulmonary plague is nearly always fatal without treatment, though it can be managed with antibiotics.3
