世界卫生组织已向俄罗斯要求提供更多信息，涉及一名西伯利亚鼠疫研究实验室工作人员的死亡事件1。俄罗斯官方正在调查死因，并表示与该研究员有过接触的人员肺鼠疫检测结果均为阴性1。美国总统特朗普表示华盛顿正在"非常认真地"关注此案1。
肺鼠疫是一种严重传染病，全球每年感染病例约为1000至3000例1。该疾病的潜伏期极短，有时仅为24小时1。如未及时诊断和治疗，肺鼠疫几乎总是致命的1，但对抗生素反应良好，早期开始治疗效果最佳1。
针对此事件对美国和英国的风险评估，美国疾病控制中心表示"没有迹象表明对美国构成更广泛的威胁"1，英国卫生安全局则称对英国民众的风险"非常低"1。
The World Health Organization has requested additional information from Russia regarding the death of a researcher at a Siberian plague research laboratory 1. Russian authorities are continuing their investigation into the cause of death and have stated that all individuals who came into contact with the deceased tested negative for pneumonic plague 1.
Pneumonic plague is a severe form of infection caused by the plague bacterium. Globally, between 1,000 and 3,000 cases of pneumonic plague are reported annually 1. The disease has an extremely short incubation period, sometimes lasting only 24 hours 1. Without prompt diagnosis and treatment, pneumonic plague is almost invariably fatal 1. However, the infection responds well to antibiotics, with early treatment initiation providing the best outcomes 1.
International health authorities have assessed the broader implications of this incident. U.S. President Trump stated that Washington is monitoring the case "very seriously" 1. The U.S. Centers for Disease Control and Prevention indicated there are "no signs that this poses a broader threat to the United States" 1. Britain's Health Security Agency assessed the risk to the British public as "very low" 1.
