The MV Hondius, a Dutch-flagged cruise ship operated by Oceanwide Expeditions, has been linked to a hantavirus outbreak that has resulted in eight confirmed infections and three deaths, including a Dutch couple and a German national. The ship departed from Ushuaia, Argentina, on April 1, 2026, and symptoms began appearing around April 6. Laboratory tests have confirmed the presence of the Andes strain of hantavirus in several cases. Passengers have been medically evacuated, while the ship is en route to the Canary Islands for disembarkation. Hantaviruses, typically transmitted through contact with infected rodent excretions, can cause severe illness, but health experts assert that the risk for most travelers remains low. They advise travelers to inquire about health protocols, monitor symptoms for up to 45 days after potential exposure, and maintain good hygiene practices. Despite the seriousness of the outbreak for those affected, experts do not recommend widespread travel restrictions, emphasizing that most journeys proceed without incident. Informed caution is advised, particularly in environments where rodent exposure is possible.
