跟进：威斯康星州一名婴儿死于麻疹：1990年以来首例死亡，全州确诊431例

位于美国中西部的威斯康星州卫生服务部（DHS）11月5日发布消息，该州一名婴儿因麻疹死亡，验尸官将麻疹列为其直接死因。这是威斯康星州自1990年以来报告的第一例麻疹死亡。卫生服务部表示，为保护家属与孩子的隐私，不会公布更多与死者有关的信息。

威斯康星州卫生服务部部长 Kirsten Johnson 在发布中表示，沉痛报告这名与该州麻疹疫情有关的婴儿死亡，她的心与这个家庭同在；每一例死亡都令人心碎，当死亡与一种可用疫苗预防的疾病有关时，更是如此。

据卫生服务部数据，截至11月5日，该州2026年已确认麻疹病例431例、9人住院、1人死亡，是该州35年多来病例数最多的一年。卫生服务部在疫情说明中提醒，已报告的病例数可能并未反映麻疹传播的全部情况，因为并非所有患者都会就医或接受检测。

这轮疫情集中在该州西南部：截至11月3日，Grant、Iowa、Lafayette 与 Vernon 四县共报告362例确诊与6例疑似病例，病毒正在当地传播；该州其他县另有散发病例，其中 Chippewa 县确认44例。州流行病学家 Ryan Westergaard 表示，这是威斯康星州35年多来见过的最大麻疹病例数，已识别的431例几乎可以肯定是低估。

卫生服务部称，截至目前通报的431例病例中，除3例之外均为未接种麻疹疫苗者。自8月1日以来，该部已向出现确诊病例社区的地方卫生部门运送2,000剂麻疹、腮腺炎与风疹联合疫苗（MMR）。该部本周更新建议：6至11个月大、暴露风险较高的婴儿可提前接种一剂 MMR 疫苗。据卫生服务部说明，两剂 MMR 疫苗预防麻疹的有效率约为97%。

Follow-Up: Wisconsin Infant Dies of Measles, the State's First Such Death Since 1990, as Cases Reach 431

The Wisconsin Department of Health Services (DHS) announced on November 5 that an infant in the state has died of measles, with the coroner listing measles as the immediate cause of death. It is the first measles death reported in Wisconsin since 1990. DHS said it would not release additional information about the child in order to protect the privacy of the family and the child.

DHS Secretary Kirsten Johnson said in the release that the department was saddened to report the death of an infant connected with the measles outbreak and that her heart was broken for the family, noting that every death is heartbreaking, and more so when it is related to a vaccine-preventable disease.

As of November 5, DHS had confirmed 431 measles cases in Wisconsin in 2026, with nine hospitalizations and one death — the highest number of cases seen in the state in more than 35 years. DHS cautioned that reported case counts may not reflect the full extent of measles spread, because not everyone who gets sick seeks care or gets tested.

The outbreak is concentrated in southwestern Wisconsin: as of November 3, Grant, Iowa, Lafayette and Vernon Counties had reported 362 confirmed and six probable cases, with measles spreading locally. Other counties have reported scattered cases, including 44 confirmed cases in Chippewa County. State epidemiologist Ryan Westergaard said this is the largest number of measles cases Wisconsin has seen in more than 35 years, and that the 431 identified cases are almost certainly an underestimate.

Of the 431 cases reported, all but three were in people who were unvaccinated, DHS said. Since August 1, DHS has delivered 2,000 doses of measles, mumps and rubella (MMR) vaccine to local health departments in communities with confirmed cases. The department this week updated its guidance to recommend an early MMR dose for certain infants aged 6 to 11 months at increased risk of exposure. Two doses of MMR vaccine are about 97 percent effective at preventing measles, according to DHS.

This story follows this site's October 30 report that Wisconsin measles cases were nearing 400, at 392; cases have since risen to 431, with the state's first measles death since 1990.
