跟进：华盛顿州居民接触感染禽流感奶牛后死亡：全美2026年首例
华盛顿州亚基马县一名在奶牛场接触感染禽流感奶牛的居民在重病后死亡，成为美国2026年首例禽流感死亡病例。据美国有线电视新闻网11月2日报道，亚基马县卫生区10月31日通报，一名接触过感染牛只的人员因重症禽流感住院，该人员有基础健康问题；11月1日，县卫生区通报该人员已经死亡。卫生区正在密切监测死者的密切接触者。
这是自2024年2月病毒首次传入奶牛以来，美国第三例禽流感死亡病例，此前已有路易斯安那州与华盛顿州的病例死亡。亚基马县卫生区今年已发现3例病例，全部自10月中旬以来出现，均因接触感染奶牛所致：其中10月15日一名奶牛场工人检测出轻症，这是近一年来的首例人类病例；第三例在刚刚过去的周末通报，症状轻微、没有住院。自10月8日以来，华盛顿州已有33个奶牛群报告感染H5N1禽流感病毒。
州卫生官员表示，已向美国疾病控制与预防中心报告全部3例病例。迄今美国没有记录到人与人之间的传播，卫生官员表示公共风险仍然较低。州政府同时敦促奶牛场工作人员穿戴个人防护装备，出现症状要及时报告。

Follow-up: Yakima County Resident Dies After Bird Flu Exposure From Infected Dairy Cows: First U.S. Death of 2026
A Yakima County, Washington, resident who caught bird flu after being exposed to infected dairy cows has died following a severe illness, becoming the first person in the United States known to die from avian influenza in 2026. According to CNN's November 2 report, the Yakima County Health District reported on October 31 that a person who had contact with infected cattle was hospitalized with a severe case of bird flu; the person had underlying health conditions. On November 1, the county reported that the person had died. Health officials are closely monitoring the person's contacts.
This is the third U.S. bird flu death since February 2024, when the virus first jumped into dairy cattle; the earlier deaths were in Louisiana and Washington. Three cases have been identified in the Yakima County Health District this year, all since mid-October and all from exposure to infected cows: a dairy worker who tested positive with a mild case on October 15, the first human case in nearly a year, and a third case reported over the weekend with mild symptoms and no hospitalization. Since October 8, 33 dairy herds infected with the H5N1 virus have been reported in Washington.
State health officials said they have reported all three cases to the U.S. Centers for Disease Control and Prevention. No human-to-human transmission has been documented in the United States, and officials say the risk to the public remains low. The state is urging dairy workers to wear personal protective equipment and report symptoms.
