A cluster of hantavirus infections was identified among passengers and crew of the MV Hondius cruise ship, resulting in several fatalities and triggering an international public health response.

在 MV Hondius 郵輪的乘客與船員中發現了一簇漢坦病毒感染個案，導致數人死亡並觸發了國際公共衛生響應。

The outbreak was clinically confirmed following the hospitalization of a British national in Johannesburg, where specialists from South Africa’s National Institute for Communicable Diseases utilized a differential diagnosis process to rule out Legionella and avian influenza. Subsequent serological testing identified the Andes strain of hantavirus. The World Health Organization (WHO) reported 11 confirmed cases and three deaths as of May 13. While hantaviruses are typically zoonotic and not transmissible between humans, the Andes strain is a documented exception, capable of person-to-person transmission via close contact.

在一名英國國民於約翰內斯堡入院後，此次爆發得到臨床證實。南非國家傳染病研究所的專家透過鑑別診斷程序，排除了軍團菌與禽流感。隨後的血清學測試確認為漢坦病毒的安地斯株。世界衛生組織 (WHO) 報告截至 5 月 13 日，共有 11 例確診病例與 3 例死亡病例。雖然漢坦病毒通常為人畜共患病且不在人與人之間傳播，但安地斯株是一個已記載的例外，能透過密切接觸在人與人之間傳播。

Historical and environmental antecedents suggest a correlation between climatic volatility and pathogen prevalence. In Argentina, a documented increase in hantavirus cases—rising from 64 in the 2024-2025 period to 101 since July of the previous year—is attributed to a sequence of severe drought followed by increased precipitation. This cycle enhanced vegetation cover, thereby augmenting the population density of rodent reservoir hosts. Similarly, in Europe, the Puumala strain's epidemiology is influenced by temperature fluctuations affecting bank vole populations, although this specific strain lacks the human-to-human transmission capability of the Andes virus.

歷史與環境前因表明，氣候波動與病原體流行率之間存在相關性。在阿根廷，漢坦病毒病例記錄到增加——從 2024-2025 年期間的 64 例增加到去年 7 月以來的 101 例——這被歸因於一連串嚴重乾旱後隨之而來的降雨量增加。此循環增加了植被覆蓋，從而提升了齧齒類儲蓄宿主的種群密度。同樣在歐洲，Puumala 株的流行病學受影響 bank vole（銀行鼴鼠）種群溫度波動的影響，儘管此特定株缺乏安地斯病毒的人傳人能力。

Institutional perspectives emphasize the necessity of a multidisciplinary approach to surveillance. Experts advocate for the integration of epidemiological data with ecological and climatic variables, such as precipitation and land-use changes. Furthermore, the International Union for Conservation of Nature (IUCN) posits that the restoration of degraded ecosystems serves as a viable public health intervention by regulating the populations of reservoir species and reducing the probability of zoonotic spillover.

機構觀點強調，監測必須採取多學科方法。專家主張將流行病學數據與生態及氣候變數（例如降雨量與土地利用變化）相整合。此外，國際自然保護聯盟 (IUCN) 認為，修復退化的生態系統可以透過調節儲蓄物種的數量並降低人畜共患溢出的可能性，作為一種可行的公共衛生干預措施。

The MV Hondius has since docked in Rotterdam for disinfection, and the WHO continues to monitor the situation while dismissing comparisons to the SARS-CoV-2 pandemic.

MV Hondius 隨後已在鹿特丹停泊進行消毒，WHO 繼續監控情況，同時否認將其與 SARS-CoV-2 大流行進行比較。
