Mapping the hantavirus outbreak as cruise ship passengers return to US
Source: USA Today
A hantavirus outbreak linked to the cruise ship MV Hondius has prompted a large-scale medical evacuation. Eighteen American passengers were flown to a military base in Omaha, Nebraska, on May 11 aboard a U.S. government medical repatriation flight. Sixteen were sequestered at the National Quarantine Center at the University of Nebraska, while two others were taken to Emory University Hospital in Atlanta. One of the Atlanta patients showed hantavirus symptoms but subsequently tested negative for the virus.
The outbreak involves the Andes variant of hantavirus, a strain associated with serious illness. In total, 94 passengers of 19 nationalities were evacuated from the vessel on May 10, the first day of evacuations. The ship had been anchored near Tenerife in Spain's Canary Islands. Passengers were transported to the island's airport via military buses and small boats, deliberately kept away from the general public to minimize any risk of wider transmission.
As of May 13, the World Health Organization reported 11 cases in total, including three deaths. Eight were laboratory-confirmed Andes virus infections, two were classified as probable, and one remained inconclusive pending further testing. A case reported by France involved a passenger who had disembarked a day before the main evacuations, highlighting concerns that new infections could continue to emerge as passengers returned to their home countries across the globe.
U.S. health officials sought to reassure the public that the situation was under control. Dr. Mehmet Oz, head of the Centers for Medicare and Medicaid Services, stated at a press briefing that the CDC was focused on treating the problem, not merely preventing future outbreaks. Health and Human Services Secretary Robert F. Kennedy Jr. echoed this sentiment, saying the government was not worried. The MV Hondius itself set sail for the Netherlands on the night of May 11.
Public health experts have used the outbreak as an opportunity to warn about the growing threat of zoonotic diseases — illnesses that spread from animals to humans. Dr. Peter Hotez of Baylor College of Medicine cautioned that while this outbreak was unlikely to escalate into a pandemic, given the limited transmission pathways of hantavirus, it serves as a significant warning sign. He stressed that zoonotic spillover epidemics are increasing in both frequency and severity, demanding greater global preparedness.
Japanese translation
クルーズ船MVホンディウスに関連したハンタウイルスの集団感染を受け、大規模な医療避難が実施された。米国人乗客18人は5月11日、米政府の医療帰国便でネブラスカ州オマハの軍事基地に搬送された。16人はネブラスカ大学の国家検疫センターに隔離され、残る2人はアトランタのエモリー大学病院へ移送された。アトランタの患者の1人はハンタウイルスの症状を示したが、検査結果は陰性だった。
今回の集団感染はハンタウイルスのアンデス変異株によるもので、重篤な症状を引き起こすことで知られる。最初の避難が行われた5月10日には、19カ国からの乗客計94人が船を降りた。船はスペイン領カナリア諸島のテネリフェ沖に停泊しており、乗客は一般市民との接触を避けるため、軍のバスや小型ボートで空港へと移送された。
世界保健機関(WHO)は5月13日時点で、死者3人を含む計11件の感染を確認したと発表した。そのうち8件は検査で確定、2件は「疑い例」、1件は追加検査中で結論が出ていない。フランスが報告した事例は、主要避難の1日前に下船した乗客に関するもので、各国帰国後も新たな感染者が出る恐れが浮き彫りとなった。
米国の保健当局者らは事態が制御下にあると国民に訴えた。メフメット・オズ博士は記者会見で、CDCが治療に重点を置いていると述べ、RFKジュニア厚生長官も懸念はないと強調した。一方、MVホンディウスは約20カ国以上の乗客を下船させた後、5月11日夜にオランダへ向けて出港した。
公衆衛生の専門家たちは今回の感染拡大を、動物から人間へ伝播する人獣共通感染症の脅威が高まっていることへの警鐘として捉えている。ベイラー医科大学のピーター・ホテズ博士は、ハンタウイルスの感染経路の限定性からパンデミックには発展しにくいとしながらも、人獣共通感染症のスピルオーバーが頻度・深刻度ともに増していると警告し、世界的な備えの必要性を訴えた。
