世界卫生组织总干事谭德塞2月28日在日内瓦宣布，将新冠肺炎疫情全球风险级别由此前的“高”上调至“非常高”。谭德塞表示，鉴于目前新冠肺炎在全球多个国家蔓延，且有越来越多国家出现疫情，故提高新冠肺炎全球风险级别。

　　The World Health Organization upgraded its coronavirus risk assessment to "very high" on Friday as cases of the novel coronavirus COVID-19 disease continue to increase and in more countries.

　　据世卫组织数据，截止到中部欧洲时间2月28日上午10点（北京时间下午5点），全球共确诊83652例新型冠状病毒病例（新增1358例）。

　　中国以外国家和地区确诊4691例（新增1027例），并有67例死亡（新增10例）。共有67个国家报告有确诊病例（昨日新增5个国家——立陶宛、尼日利亚、新西兰、白罗斯和圣马力诺）。

　　"The continued increase in the number of cases, and the number of affected countries over the last few days, are clearly of concern," said the WHO's Director-General Tedros Adhanom Ghebreyesus.

　　"We have now increased our assessment of the risk of spread and the risk of impact of COVID-19 to very high at a global level," he said.

　　谭德塞强调，控制疫情的关键是阻断病毒传播链条(chains of transmission)。如果采取强有力的行动尽早发现病例、对病人进行隔离和护理、追踪密切接触者，“我们仍有机会控制这种病毒”。

　　"As long as that's the case, we still have a chance of containing this virus, if robust action is taken to detect cases early, isolate and care for patients and trace contacts," Tedros said.
