The reference archive for the MV Hondius hantavirus outbreak.

Hantavirus Cruise (hantaviruscruise.com) is an independent, single-topic publication. We exist to do one thing well: maintain the most accurate, best-sourced, continuously updated record of the Andes hantavirus outbreak aboard the MV Hondius — from the ship's departure from Ushuaia on 1 April 2026 through the resolution of the cluster and its public-health follow-up.

What we cover

The voyage itself, day by day. The ship and its operator. The pathogen — Andes virus (ANDV) — its biology, transmission, clinical course, and treatment. The official response from WHO, ECDC, and national health authorities. The passengers and crew, including the disembarked contacts being traced across multiple countries. And the wider context: how cruise-ship outbreaks are managed, why this one is unprecedented, and what it changes for expedition cruising.

How we work

Every claim links back to a primary source — a WHO Disease Outbreak News bulletin, an ECDC threat assessment, a national health-ministry statement, an operator press release, or a peer-reviewed reference for the underlying virology. Where reporting conflicts, we publish the discrepancy and let the sources speak. Updates are timestamped in UTC. A change log is kept for every page.

What we are not

We are not a medical authority and we do not provide medical advice. If you were a passenger or crew member on the MV Hondius — or in close contact with one — contact your national public-health authority directly. Useful starting points are linked from the Health Advisory section.
