世界卫生组织（世卫组织）周三表示确实如此西伯利亚一名鼠疫实验室工作人员死亡后，俄罗斯当局目前没有足够的信息进行全面的风险评估。
世卫组织总干事Tedros Adhanom Ghebreyesus博士在新闻发布会上说，在媒体报道该工人死亡后，世卫组织根据《国际卫生条例》（ IHR）于周六要求俄罗斯联邦提供更多信息。
俄罗斯联邦周二回应称，西伯利亚东南部的伊尔库茨克州最近没有报告鼠疫病例，约200名接触者已被隔离。
谭德塞在开场白中说：“由于我们还不了解这一事件的全貌，我们无法进行全面的风险评估。”。“根据《国际卫生条例》，及时、完整和透明的信息共享对于澄清相互矛盾的报告和准确评估潜在的公共卫生风险至关重要。”
最初的媒体报道称，伊尔库茨克安蒂普拉格研究所的一名实验室工作人员死于鼠疫，但俄罗斯官员后来否认了这一说法，称该工作人员死于肺炎和肺炎这种疾病与实验室工作无关。
谭德塞说，世卫组织已经要求提供更多有关实验室工作人员死亡的信息，对死亡人员进行的测试，与该工作人员密切接触的其他人的追踪，以及其他信息。
“我们不知道这个人到底是怎么死的，”世卫组织卫生应急计划流行病和疫情管理部主任Maria Van Kerkhove博士周三告诉记者。“我们知道她患了肺炎。我们知道这是一个致命的案例。我们知道已经做了一些实验室测试。据我们所知，他们还没有找到病原体，所以这就是为什么我们需要更多的信息。”
看来世卫组织可能严重依赖当地媒体的报道，以更好地了解可能发生了什么。
在回答记者关于实验室潜在事件的问题时，克霍夫指出，“我知道你从媒体那里知道的。”
Van Kerkhove说，世卫组织正在等待俄罗斯官员提供关于该事件的更多信息。
“我们期待俄罗斯的进一步答复。在IHR提出核查要求后，我们确实从他们那里得到了一些报告，但还没有全部提供给我们。 谭德塞补充说，世卫组织提供了与鼠疫和实验室生物安全和生物安保有关的技术支持。
周二，疾病控制和预防中心在一份报告中说声明在某种程度上，“目前，没有迹象表明美国面临更广泛的威胁，但疾病预防控制中心和我们的跨部门合作伙伴已经做好准备，并将继续密切监控局势。”
鼠疫是由鼠疫杆菌引起的疾病，根据疾病控制中心的说法。鼠疫有三种类型：淋巴腺鼠疫、肺鼠疫和败血症鼠疫。症状通常包括发烧、发冷和虚弱。瘟疫可以用抗生素治疗。越早接受抗生素治疗，完全康复的机会就越大。
根据美国疾病预防控制中心的数据，美国平均每年约有七起鼠疫病例，主要是在西部各州，该中心指出，美国已经有一个多世纪没有出现有记录的鼠疫人际传播病例了。
WHO officials say unclear how Russia plague lab worker died， call for more information
The World Health Organization （WHO） said on Wednesday it doesnot currently have enough information from Russian authorities to conduct a full risk assessment after the death of a plague laboratory worker in Siberia．
Dr． Tedros Adhanom Ghebreyesus， WHO director-general， said during a press conference that following media reports of the worker＇s death， the WHO asked the Russian Federation on Saturday for more information， in accordance with the International Health Regulations （IHR）．
The Russian Federation replied on Tuesday， saying no case of plague had recently been reported in the Irkutsk oblast， in southeastern Siberia， and that about 200 contacts had been placed in quarantine．
＂As we don＇t yet have the full picture of this event， we are not able to conduct a full risk assessment，＂ Tedros said in his opening remarks． ＂Timely， complete and transparent information sharing under the International Health Regulations is essential to clarify conflicting reports and enable an accurate assessment of potential public health risks．＂
Initial media reports suggested a lab worker at Irkutsk Antiplague Research Institute died of the plague， but Russian officials later disputed this， saying the worker died of pneumonia andthat the illness was not linked to work in the lab．
Tedros said the WHO has requested more information surrounding the death of the lab worker， the tests being conducted on the individual who died， contact tracing of other individuals close to the worker， and other information．
＂We don＇t know exactly how this person died，＂ Dr． Maria Van Kerkhove， director of the department of epidemic and pandemic management of the WHO Health Emergencies Program， told reporters on Wednesday． ＂We know that she had pneumonia． We know it was a fatal case． We understand that some laboratory tests have been done． They haven＇t found the causative agent， that we know， and so this is why we need more information．＂
It appears that the WHO may have leaned heavily on local media reports to better understand what may have occurred．
In response to a reporter＇s question about a potential incident in the lab， Kerkhove noted， ＂I know what you know from the media．＂
The WHO is awaiting more information from Russian officials regarding the incident， Van Kerkhove said．
＂We expect further answers from Russia． We did get some reports back from them following the IHR verification request， but not yet everything has been provided to us，＂ Van Kerkhove said．
Tedros added that the WHO has offered technical support related to plague and lab biosafety and biosecurity．
On Tuesday， the Centers for Disease Control and Prevention said in astatement， in part， that ＂at this time， there is no indication of a broader threat to the United States， but CDC and our interagency partners are prepared and will continue to monitor the situation closely．＂
Plague is a disease caused by the bacterium Yersinia pestis，according to the CDC． There are three types of plague： bubonic， pneumonic and septicemic． Symptoms often include fever， chills and weakness． Plague can be treated with antibiotics． The earlier antibiotics are received， the higher the chances of a full recovery．
The U．S． averages about seven cases of plague each year， mostly in Western states， according to the CDC， which notes it has been more than a century since the U．S． has seen a documented case of person-to-person spread of plague．
