跟进：威斯康星州麻疹病例突破300例：居全美第四，疫苗覆盖率下滑被指主因
威斯康星州卫生服务部10月23日更新的数据显示，该州2026年麻疹确诊病例已达308例，分布在8个县的持续暴发中：拉法叶县（Lafayette）103例、格兰特县（Grant）77例、爱荷华县（Iowa）74例、奇珀瓦县（Chippewa）28例、弗农县（Vernon）14例、马拉松县（Marathon）6例、罗克县（Rock）5例疑似、里奇兰县（Richland）1例，疫情自7月初开始。其中奇珀瓦县增幅最大，病例数较上周翻了一倍多。本站10月11日曾报道该州病例升至263例。
据《密尔沃基哨兵报》报道，截至10月22日，全美今年已报告近4600例麻疹病例，威斯康星州病例数居全美第四，仅次于宾夕法尼亚州、南卡罗来纳州和犹他州。医疗专家指出，根本原因是麻疹疫苗接种覆盖率下滑。
美国于2000年获得麻疹消除认证（即疾病不再持续传播），但今年可能失去这一地位；世界卫生组织相关委员会预计11月在华盛顿开会投票决定。

Follow-Up: Wisconsin Measles Cases Pass 300, Still Fourth in Nation as Vaccination Coverage Slips
Wisconsin has surpassed 300 measles cases in 2026 tied to outbreaks in eight counties, according to the latest data from the Wisconsin Department of Health Services reported on October 23. The 308 cases are distributed as follows: 103 in Lafayette County, 77 in Grant County, 74 in Iowa County, 28 in Chippewa County, 14 in Vernon County, 6 in Marathon County, 5 probable cases in Rock County and 1 in Richland County, in outbreaks that began in early July. The largest increase came from Chippewa County, where the count more than doubled since last week. GSM reported on October 11 that the state's cases had risen to 263.
As of October 22, close to 4,600 measles cases have been reported in the United States this year, according to the CDC, and Wisconsin remains the state with the fourth-most cases, behind Pennsylvania, South Carolina and Utah, the Milwaukee Journal Sentinel reported. Experts say the basic reason is slipping measles vaccination coverage.
The country could likely lose its measles elimination status, granted in 2000, meaning the disease does not circulate continuously; a World Health Organization commission is expected to vote on the decision at a meeting in Washington, D.C., in November.
