美国疾病控制与预防中心（CDC）报告称，美国已出现第三例因麻疹死亡的病例，该国正面临数十年来最大规模的麻疹疫情。
The Centers for Disease Control (CDC) has reported that a third person has died due to measles in the United States, as the country grapples with its largest measles outbreak in decades.
CDC周二未说明死亡病例发生在哪个州。该机构的全国统计数字仍低于州官员报告的麻疹相关死亡数，特别是受疫情冲击最严重的宾夕法尼亚州。截至周一，宾夕法尼亚州已报告1,286例病例和五例死亡。
The CDC did not specify on Tuesday in which state the death occurred. The agency’s national tally remains lower than the number of measles-related deaths reported by state officials, particularly in Pennsylvania, the state hardest hit by the outbreak. Pennsylvania had reported 1,286 cases and five deaths as of Monday.
CDC周二确认了一例死亡，此前国家卫生统计中心核实，死亡证明上将麻疹列为根本死因。
The CDC confirmed a death on Tuesday after the National Center for Health Statistics verified that measles was listed as the underlying cause of death on a death certificate.
截至10月15日，CDC报告全国麻疹病例达4,410例。该机构表示，随着进一步审查完成，其死亡统计数字可能会发生变化。宾夕法尼亚州的疫情已蔓延至最初的兰开斯特县疫情中心之外，目前已有42个县报告病例。
The CDC reported 4,410 measles cases nationwide as of October 15. The agency has said its death count could change as further reviews are completed. The outbreak in Pennsylvania has spread well beyond its initial epicentre in Lancaster County, with 42 counties now reporting cases.
联邦政府统计麻疹死亡的方法引发关注，此前CDC改为依赖国家卫生统计中心（NCHS）的死亡率数据，而非州卫生部门的报告。
The federal government’s approach to counting measles deaths has drawn scrutiny after the CDC shifted to relying on mortality data from the National Center for Health Statistics (NCHS) rather than state health departments’ reports.
CDC此前曾告诉半岛电视台，正与州和地方流行病学家委员会合作，建立麻疹死亡的标准化定义。在此期间，他们将使用NCHS死亡率数据作为衡量标准。
The CDC has previously told Al Jazeera that it is working with the Council of State and Territorial Epidemiologists to establish a standardised definition for measles deaths. In the meantime, they will use NCHS mortality data as their measure.
