Background

MV Hondius is a Dutch-flagged expedition cruise ship operated by Oceanwide Expeditions, named after the Dutch cartographer Jodocus Hondius. Built in 2019, she has a passenger capacity of approximately 170 and specialises in Antarctic and Arctic expedition cruises departing primarily from Ushuaia, Argentina, for the Southern Ocean, and from Longyearbyen, Norway, for the Arctic. The vessel is rated for Polar Code operation and carries a scientific expedition programme alongside tourism. Berth prices typically range from €6,000 to €15,000 per passenger. MV Hondius is registered in the Netherlands; Oceanwide Expeditions is headquartered in Middelburg, Netherlands.

MV Hondius was the site of an Andes hantavirus cluster that surfaced in early 2026 after departing Ushuaia, Argentine Tierra del Fuego. By 7 May 2026 the cluster stood at 8 cases, 3 deaths, 1 critically ill across passengers and crew from 23 nationalities. A Swiss passenger who disembarked later tested positive for Andes virus, the only hantavirus capable of person-to-person transmission, triggering active European contact tracing. The departure date recorded by WHO DON 599 (1 April) and Africa CDC (20 March) conflict; the discrepancy determines whether HCPS incubation points to pre-boarding exposure in Ushuaia or at-sea transmission. The vessel was moored off Cabo Verde when WHO published DON 599 on 2 May.
