跟进：全美麻疹病例升至5,412例 一周新增230例、96%与疫情相关

亚特兰大 — 美国疾病控制与预防中心（CDC）11月13日更新全美麻疹病例与疫情数据：截至11月12日，美国2026年已报告5,412例确诊麻疹病例，比上一次更新的5,182例（截至11月5日）一周增加230例。

这5,412例中，5,394例由47个司法辖区报告，包括加利福尼亚州、德州、宾夕法尼亚州与纽约州等地，另有18例为国际访客在美期间报告的病例。CDC 说明，本页数据只计入各辖区正式通报的确诊病例，不含疑似病例，各州卫生部门掌握本地最新情况。

疫情关联方面，2026年以来全美已报告43起新的麻疹疫情（3例或以上关联病例为一起），96%的确诊病例与疫情相关，共5,216例，其中3,831例来自2026年新发生的疫情，1,385例来自2025年开始、延续至今的疫情。

死亡方面，CDC 确认2026年全美麻疹相关死亡共6例，这一数字可能随后续复核调整。CDC 正与州和地区流行病学家理事会（CSTE）合作，制定统一的麻疹死亡病例定义，让各辖区的分类与报告口径一致。

作为对照，2025年全年全美共报告2,289例确诊麻疹病例，2026年至今的病例数已是去年全年的两倍多。美国于2000年宣布消除本土麻疹传播，泛美卫生组织下辖委员会对美国麻疹消除地位的审查决定尚未公布。

Follow-up: U.S. Measles Cases Rise to 5,412, Up 230 in a Week, 96% Outbreak-Associated

Atlanta — The U.S. Centers for Disease Control and Prevention (CDC) updated its national measles case and outbreak data on November 13: as of November 12, 5,412 confirmed measles cases had been reported in the United States in 2026, up 230 from the previous update of 5,182 cases (as of November 5).

Of the 5,412 cases, 5,394 were reported by 47 jurisdictions, including California, Texas, Pennsylvania and New York, and 18 cases were reported among international visitors to the United States. CDC notes that the page counts only confirmed cases notified by jurisdictions, not probable cases, and that state health departments hold the most up-to-date local information.

On outbreaks, 43 new measles outbreaks (three or more related cases) have been reported in 2026, and 96% of confirmed cases, 5,216 in total, are outbreak-associated: 3,831 from outbreaks that started in 2026 and 1,385 from outbreaks that started in 2025.

CDC has confirmed six measles-associated deaths in the United States in 2026, a figure subject to change as reviews are completed. CDC is working with the Council of State and Territorial Epidemiologists (CSTE) to develop a standardized case definition for deaths due to measles, to promote consistent classification and reporting across jurisdictions.

By comparison, 2,289 confirmed measles cases were reported in the United States in all of 2025, so the 2026 total to date is already more than double last year's full-year figure. Measles was declared eliminated in the United States in 2000, and a Pan American Health Organization committee decision on the country's measles elimination status has not yet been announced.
