跟进：CDC确认2026年第三例麻疹相关死亡 全美确诊病例维持4,410例

美国疾病控制与预防中心（CDC）在其「麻疹病例与疫情」数据页上确认，2026年全美麻疹相关死亡已升至3例。本站今晨依据CDC数据发布报道时，联邦口径为2例，此次更新增加1例。CDC在数据页的脚注中说明，这一数字仍可能变动，中心将在获得更多信息、相关复核完成后更新报告。据路透社报道，CDC没有公布3例死亡分别发生在哪个州，主管CDC的卫生与公众服务部（HHS）未即时回应置评请求。

病例总数没有变化：CDC数据显示，截至10月15日，全美2026年累计确诊麻疹病例4,410例，分布在47个辖区，另有18例为到访美国的国际访客；今年以来共报告42起疫情，96%的确诊病例与疫情相关。CDC同时表示，正与州及领地流行病学家理事会（CSTE）合作制定统一的麻疹死亡病例定义，以统一各辖区的分类与报告口径。

联邦与州的口径差异仍在：宾夕法尼亚州卫生部门报告该州今年已有5例麻疹相关死亡，高于CDC的全国确认数。本站此前报道，宾州是今年疫情最重的州，CDC本月已应宾州请求增派人员赴当地协助调查。CDC数据还显示，美国幼儿园儿童的MMR（麻疹、腮腺炎和风疹）疫苗接种率在2025至2026学年降至92.4%，低于95%的群体防护目标，约28万名幼儿园儿童面临感染风险。

Follow-Up: CDC Confirms Third Measles-Related Death in 2026, U.S. Cases Hold at 4,410

The U.S. Centers for Disease Control and Prevention (CDC) has confirmed on its measles cases and outbreaks data page that measles-related deaths in the United States in 2026 have risen to three. The federal count stood at two in GSM's report earlier today based on CDC data; the updated page adds one death. In a footnote, the CDC says the number is subject to change and that it will update its reporting as additional information becomes available and relevant reviews are completed. According to Reuters, the CDC did not specify in which states the deaths occurred, and the Department of Health and Human Services (HHS), which oversees the CDC, did not immediately respond to a request for comment.

The case total is unchanged: as of October 15, the CDC counts 4,410 confirmed measles cases in the United States in 2026, reported by 47 jurisdictions, plus 18 cases among international visitors. There have been 42 outbreaks reported in 2026, and 96 percent of confirmed cases are outbreak-associated. The CDC also says it 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.

The gap between federal and state counts remains: Pennsylvania's health department reports five measles-related deaths in that state this year, above the CDC's confirmed national figure. Pennsylvania is the hardest-hit state in this year's outbreak, and GSM previously reported that the CDC has sent additional personnel to the state at its request to help with the investigation. CDC data also show that MMR (measles, mumps and rubella) vaccination coverage among U.S. kindergartners fell to 92.4 percent in the 2025-2026 school year, below the 95 percent community-protection target, leaving approximately 280,000 kindergartners at risk.
