Argentine and United States health authorities are conducting a joint epidemiological investigation to identify the origin of an Andes hantavirus outbreak that occurred aboard the cruise ship MV Hondius.

阿根廷與美國衛生部門正進行聯合流行病學調查，以確定在 MV Hondius 郵輪上爆發的安第斯漢坦病毒之源頭。

The outbreak involved 13 confirmed cases and three fatalities, beginning after the vessel's departure from Ushuaia in April. The pathogen identified is the Andes hantavirus strain, which is endemic to Argentina and Chile. Notably, this specific strain is distinguished by its capacity for human-to-human transmission in enclosed environments, a characteristic absent in most other hantavirus strains. The primary index cases are believed to be a Dutch couple; investigators hypothesize that the initial contagion resulted from exposure to infected rodent excreta during their transit through Argentina and Chile.

此次爆發涉及 13 例確診個案與 3 宗死亡個案，始於該船 4 月離開烏舒愛亞之後。鑑定出的病原體為安第斯漢坦病毒株，該病毒在阿根廷與智利為地方性流行。值得注意的是，此特定病毒株在封閉環境中具有人傳人的能力，而大多數其他漢坦病毒株則不具此特性。初步 index 個案被認為是一對荷蘭夫婦；調查人員假設最初的感染是由於他們在通過阿根廷與智利期間，接觸到受感染的齧齒類動物排泄物所致。

Institutional efforts to localize the source have led to a divergence in stakeholder positioning. While the Argentine Health Ministry initially identified Ushuaia as a potential origin, local authorities in Tierra del Fuego have contested this assertion, citing a thirty-year absence of recorded hantavirus cases in the region. Consequently, the investigation has expanded to the province of Mendoza. From June 8 to 12, specialists from the Malbran Institute and the U.S. Centers for Disease Control and Prevention (CDC) will execute field studies in Malargüe, where the Dutch couple had previously traveled. This operation involves the collection of blood samples from deceased rodents for laboratory analysis in Buenos Aires.

機構在定位源頭的努力導致利益相關者的立場出現分歧。雖然阿根廷衛生部最初將烏舒愛亞列為潛在源頭，但火地島當地政府對此主張提出異議，理由是該地區 30 年來未有漢坦病毒個案紀錄。因此，調查範圍已擴大至門多薩省。6 月 8 日至 12 日，來自 Malbran 研究所與美國疾病管制與預防中心（CDC）的專家將在馬拉格韋進行實地研究，該地為該對荷蘭夫婦先前造訪之處。此行動包括收集死後齧齒類動物的血液樣本，以便在布宜諾斯艾利斯的實驗室進行分析。

Despite a mortality rate reaching 30% and the absence of approved vaccines or therapeutic interventions, the World Health Organization (WHO) has maintained that the event does not constitute a pandemic threat. The WHO continues to coordinate with national governments regarding the monitoring of repatriated passengers from over 20 countries currently in specialized quarantine.

儘管死亡率高達 30%，且缺乏核准的疫苗或治療干預措施，但世界衛生組織（WHO）維持原見，認為此次事件不構成大流行威脅。WHO 繼續與各國政府協調，監控目前在專門隔離區中、來自 20 多個國家的遣返乘客。

The investigation remains ongoing, with laboratory results from rodent samples in both Ushuaia and Mendoza pending.

調查仍在進行中，目前正等待烏舒愛亞與門多薩齧齒類動物樣本的實驗室結果。
