邮轮安第斯病毒疫情致3人死亡：疾控中心公布调查，美国88名接触者完成42天监测无续发
美国疾病控制与预防中心（CDC）11月5日在《发病率与死亡率周报》（MMWR）发布调查报告：2026年5月4日，CDC 接到通报，一艘航行于大西洋的邮轮上出现 7 例重症急性呼吸道疾病、其中 3 人死亡，后经确认由安第斯病毒（Andes virus）引起；与这艘邮轮相关的 88 名美国居民接触者全部完成 42 天监测，未发现续发感染。
这艘邮轮从阿根廷出发，船上共有 147 人，包括 88 名乘客与 59 名船员，人员国籍涵盖 23 个国家。指示病例 4 月 3 日发病，最初的患者出现发热与胃肠道症状，其中 4 人迅速进展为呼吸衰竭与休克。1 名危重乘客 4 月 27 日被医疗转运至南非，5 月 5 日检测确认为安第斯病毒感染。船上乘客被建议留在舱房内并尽量保持距离；邮轮 5 月 10 日停靠西班牙加那利群岛的 Tenerife，余下乘客下船接受医疗与公共卫生协助。
美国接触者共 88 人，分布在 27 个辖区。28 人是邮轮乘客，其中 10 人在确认船上感染之前已经下船，余下 18 人 5 月 10 日离开 Tenerife、5 月 11 日乘美国国务院包机回国，送往位于 Omaha 的内布拉斯加大学医学中心国家隔离单元接受评估与监测；另外 60 人与一名有症状的确诊乘客同乘 4 月 25 日的两段航班，航线为 Saint Helena 至 Johannesburg、Johannesburg 至 Amsterdam。全部 88 人完成了 42 天监测，127 份 PCR 检测结果全部为阴性。在全球范围，33 个国家的地方卫生部门共评估、监测了约 653 名可能暴露者。
CDC 介绍，安第斯病毒流行于南美部分地区，是已知唯一可以人传人的汉坦病毒，通过与有症状感染者的密切长时间接触或体液暴露传播，潜伏期 4 至 42 天，可引发汉坦病毒肺综合征，报告病死率约 40%，目前没有特效治疗方法与疫苗。美国此前仅在 2018 年报告过 1 例输入性安第斯病毒病例。CDC 表示，医务人员对有安第斯病毒流行地区旅行史、或接触过疑似或确诊感染者之后出现相符症状的患者，应考虑安第斯病毒感染，并及时通知公共卫生部门。
Andes Virus Outbreak on Cruise Ship Killed 3: CDC Reports 88 U.S. Contacts Monitored With No Secondary Cases
The U.S. Centers for Disease Control and Prevention (CDC) published an investigation report in its Morbidity and Mortality Weekly Report (MMWR) on November 5: on May 4, 2026, CDC was notified of seven cases of severe acute respiratory illness, including three deaths, aboard a cruise ship in the Atlantic Ocean, later confirmed to be caused by Andes virus (ANDV). All 88 U.S. resident contacts linked to the ship completed 42 days of monitoring, and no secondary infections were identified.
The ship had departed from Argentina with 147 people on board, 88 passengers and 59 crew members of 23 nationalities. The index patient developed symptoms on April 3; the first patients had fever and gastrointestinal symptoms, and four rapidly progressed to respiratory failure and shock. One critically ill passenger was medically evacuated to South Africa on April 27, and testing there confirmed ANDV infection on May 5. Passengers were advised to remain in their cabins and maximize distancing; the vessel docked at Tenerife in Spain's Canary Islands on May 10, where the remaining passengers disembarked for medical and public health assistance.
The 88 U.S. contacts lived in 27 jurisdictions. Twenty-eight were cruise passengers: 10 had disembarked before ANDV infection was confirmed on board, and the other 18 left Tenerife on May 10 and arrived in the United States on May 11 aboard a U.S. Department of State chartered flight, and were taken to the National Quarantine Unit at the University of Nebraska Medical Center in Omaha, Nebraska, for assessment and monitoring. The other 60 contacts had shared two April 25 flights, from Saint Helena to Johannesburg, South Africa, and from Johannesburg to Amsterdam, Netherlands, with a symptomatic passenger later confirmed to have ANDV infection. All 88 contacts completed 42 days of monitoring, the upper end of the known ANDV incubation period, and all 127 PCR tests were negative. Worldwide, local health authorities assessed and monitored about 653 potentially exposed people from 33 countries.
CDC says Andes virus is endemic to parts of South America and is the only hantavirus known to spread person to person, through close prolonged contact with a symptomatic person or exposure to their body fluids. Its incubation period is 4 to 42 days, and infection can cause hantavirus pulmonary syndrome, which has a reported case-fatality rate of about 40 percent; there is no specific treatment or vaccine. The United States had previously reported one documented imported ANDV case, in 2018. CDC says clinicians should consider ANDV infection in patients with compatible illness after travel to areas where the virus is endemic or exposure to a person with suspected or confirmed infection, and promptly notify public health authorities.
