ハンタウイルスとは?
ハンタウイルスは主に齧歯類が保有する RNA ウイルス科 (Orthohantavirus 属) です。ヒトは齧歯類の糞・尿・唾液からのエアロゾルを吸入することで感染します。ウイルスの種類により、ユーラシアでは腎症候性出血熱 (HFRS)、アメリカ大陸ではハンタウイルス肺症候群 (HPS) のいずれかの臨床像を呈します。
背景
WHO、CDC、ECDC、PAHO と照合した参考概要。
ハンタウイルスは主に齧歯類が保有する RNA ウイルス科 (Orthohantavirus 属) です。ヒトは齧歯類の糞・尿・唾液からのエアロゾルを吸入することで感染します。ウイルスの種類により、ユーラシアでは腎症候性出血熱 (HFRS)、アメリカ大陸ではハンタウイルス肺症候群 (HPS) のいずれかの臨床像を呈します。
MV Hondius に関連した症例は、南アフリカ NICD およびオランダ RIVM により アンデス型 Orthohantavirus (ANDV) として実験室確定されています。アンデスウイルスは ヒトーヒト感染が文書化された唯一のハンタウイルス で、アルゼンチン南部とチリでの流行で初めて観察されました。報告された症例集積では致死率 30〜50% の重症 HPS を引き起こします。
潜伏期は 1〜6 週間 (通常 2〜4 週間) です。初期症状は非特異的で、発熱、倦怠感、強い筋肉痛、頭痛、時に消化器症状を伴います。発症 4〜10 日後に咳・呼吸困難・肺水腫・心原性ショックを伴う心肺期へ急速に進行することがあり、これが HPS の主要な死因となります。
アンデスウイルスに対する特異的な抗ウイルス療法や承認済みワクチンはありません。治療は支持療法が中心で、集中治療室での酸素投与、人工呼吸、循環動態管理を行います。予防は齧歯類の排泄物への曝露を避けることに重点が置かれ、本流行では MV Hondius の同船者・乗組員の接触者追跡が行われています。
本概要は文脈共有のためのものであり、医療助言ではありません。最近 MV Hondius に乗船された方、または曝露が疑われる方は、ご自身の国の保健当局にご相談ください。

よくある質問
ハンタウイルスと本流行に関するよくある質問への簡潔な回答。
MV Hondius はオランダの Oceanwide Expeditions が運航する探検クルーズ船で、定員 108 名です。本流行は、ヒトーヒト感染が文書化された唯一のハンタウイルスである <strong>アンデス型 Orthohantavirus</strong> によるものであり、乗客の移動を介して複数国に拡散したことから重要視されています。
船舶は現在、最新の医療搬送が行われたカーボベルデ近海の大西洋上にあります。リアルタイム位置は MarineTraffic の IMO 9818709 を参照してください。
はい。アンデス型 Orthohantavirus (ANDV) は、ヒトーヒト感染が文書化された唯一のハンタウイルスで、アルゼンチン南部とチリの流行で観察されています。このため、乗船者全員に対して接触者追跡が実施されています。
報告された症例集積では、アンデスウイルス肺症候群の致死率は 30〜50% です。発症から 4〜10 日後に始まる心肺期が、主な死因となります。
はい。南アフリカ NICD、オランダ RIVM、GGD Kennemerland、ドイツ RKI、スイス BAG、シンガポール CDA、英国 UKHSA など各国保健当局が接触者を追跡・観察しています。本サイトの患者登録には判明した個人と接触者グループが掲載されています。
調査は、乗船前のアルゼンチンでの曝露 (当初はウシュアイア、現在ではチュブト・リオネグロ・ネウケン) に焦点を当てています。アンデスウイルスはアルゼンチン南部とチリで地域的に流行しています。具体的な助言は、ご自身の国の保健当局にご相談ください。
診断は、参照ラボで血液または呼吸器検体を RT-PCR で検査することにより行われます。本流行での確認は、南アフリカ NICD、オランダ RIVM、ドイツ RKI Konsiliarlabor、ジュネーブ HUG により実施されました。
