华盛顿州亚基马县一名居民因禽流感并发症死亡，公共卫生官员证实，这标志着美国出现了一例罕见的禽流感致死人类病例。
A resident of Yakima County, Washington, has died from complications of bird flu, public health officials confirmed, marking a rare fatal human case of the virus in the United States.
该患者有基础疾病，在当地一家奶牛场接触受感染牲畜后感染禽流感，随后因重症住院治疗。出于隐私考虑，当地官员拒绝透露死者姓名、年龄或性别。
The individual, who had underlying medical conditions, was hospitalized with severe illness after contracting avian influenza through exposure to infected livestock at a local dairy facility. Local officials declined to release the person’s name, age or gender, citing privacy concerns.
亚基马卫生区卫生官员戴夫·阿特伯里博士在声明中说：“我们向死者家属和亲友致以深切慰问。”
"Our hearts go out to the individual's family and loved ones during this difficult time," Dr. Dave Atteberry, health officer for the Yakima Health District, said in a statement.
他接着说：“禽流感可导致重症，尤其是有基础健康问题的人群。虽然这是一个严重且令人心碎的结果，但对普通公众的风险仍然较低。”
"Avian influenza can cause severe illness, particularly among people who have underlying health conditions," he went on. "While this is a serious and heartbreaking outcome, the risk to the general public remains low."
卫生官员周一还确认了亚基马县第三例禽流感人类病例。该患者同样在当地农场接触受感染奶牛，未住院且未出现重症。
Health officials on Monday also confirmed a third human case of avian influenza in Yakima County. That individual, who was also exposed to infected dairy cattle at a local farm, has not been hospitalized and has not experienced severe illness.
公共卫生团队正在积极追踪并监测这两名患者的密切接触者是否出现潜在症状。
Public health teams are actively tracing and monitoring close contacts of both individuals for potential symptoms.
卫生区在一份通告中说：“高风险人群包括奶牛场工人以及其他与受感染动物或被病毒污染的环境有密切或长时间接触的人。”
"People at greater risk include dairy workers and others who have close or prolonged contact with infected animals or environments contaminated with the virus," the health district said in an advisory.
“如果您在奶牛场工作，在潜在接触受感染奶牛后出现症状，请联系您的医疗服务提供者或亚基马卫生区。”
"If you work on a dairy farm and develop symptoms after potential exposure to infected cattle, contact your health care provider or the Yakima Health District."
根据美国疾病控制与预防中心的说法，禽流感是由甲型流感病毒引起的疾病，通常在野生水禽和家禽中传播。
Avian influenza, or bird flu, is a disease caused by influenza type A viruses that typically spread among wild aquatic birds and domestic poultry, according to the Centers for Disease Control and Prevention.
近年来，H5N1毒株的疫情已扩散至鸟类以外，感染多种哺乳动物，包括家养奶牛和户外牲畜。联邦和州卫生官员强调，对普通公众的总体风险仍然很低。
In recent years, an outbreak of the H5N1 strain has expanded beyond birds to infect various mammals, including domestic dairy cows and outdoor livestock. Federal and state health officials emphasize that the overall risk to the general public remains low.
根据美国疾控中心（CDC）的说法，禽流感在人与人之间传播极为罕见，且在美国尚未发现此类传播。
Person-to-person spread of bird flu is extremely rare and has not been identified in the U.S., according to the CDC.
上述机构指出，农业工人、兽医以及与受感染动物、生奶或受污染粪便有密切、长时间接触的人员，面临最高的暴露风险。
Agricultural workers, veterinarians and people in close, prolonged contact with infected animals, raw milk or contaminated manure are at the greatest risk of exposure, the above agency states.
商业巴氏杀菌奶和彻底煮熟的禽肉仍然可以安全食用，因为高温能杀灭病毒。
Commercial pasteurized milk and properly cooked poultry remain safe to consume, as heat kills the virus.
人感染禽流感的症状可轻可重。近期与农场相关的病例中报告的最常见症状包括以下内容。卫生部门建议公众避免接触生病或死亡的野生鸟类和家畜。
Bird flu infections in humans can range from mild to severe. The most common symptoms reported in recent farm-related cases include the following. Health authorities advise the public to avoid handling sick or dead wild birds and livestock.
农场人员和奶牛场工人在接触可能受感染的家畜或受污染表面时，应佩戴建议的个人防护装备——如 N95 呼吸器、护目镜和防液体手套。任何人在接触动物后出现呼吸道或眼部症状，应及时就医评估。
Farm personnel and dairy workers should wear recommended personal protective equipment — such as N95 respirators, eye goggles and fluid-resistant gloves — whenever handling potentially infected livestock or contaminated surfaces. Anyone developing respiratory or eye symptoms after animal exposure should seek medical evaluation promptly.
亚基马卫生区每周两次、分别在周一和周四下午 2 点更新当地禽流感病例数字和指导建议。
The Yakima Health District updates its local avian influenza case figures and guidance twice weekly, on Mondays and Thursdays at 2 p.m.
