Hantavirus outbreak linked to cruise ship travel, Multi-locations was recorded by Global Incident Tracker on Thursday, 28 May 2026 at 14:43 UTC. The event is classified as a epidemic incident with a severity rating of Severe, and was detected through the World Health Organization (WHO).
This is the fourth Disease Outbreak News report on the Andes hantavirus outbreak linked to cruise ship travel, following the notification to the World Health Organization (WHO) on 2 May 2026 of severe respiratory illness cases aboard M/V Hondius, a cruise ship. Since the last DON was published on 13 May, three additional confirmed cases were reported, from Canada, the Netherlands, and Spain. The previously reported inconclusive case from the United States of America was subsequently determined to be negative following further laboratory testing and has been removed from the total case count. All cases to date have been passengers or crew members on the ship. As of 27 May, a total of 13 cases, including three deaths, have been reported (case fatality ratio 23%). Eleven cases have been laboratory-confirmed for Andes virus (ANDV) infection, and two are probable cases. Given the long incubat

Understanding epidemic events
Disease outbreaks including cholera, dengue, measles, Ebola and influenza. Outbreak trajectories depend on transmission route, population immunity and the speed of detection. Early case-finding, clean water and vaccination coverage change outcomes far more than late-stage restrictions.
How severity is rated
Global Incident Tracker rates every event on a four-step scale — Minor, Moderate, Severe and Extreme — derived from the source signal: earthquake magnitude, official GDACS alert colour, or the volume of independent media reporting for news-derived incidents. This event is currently rated Severe. Ratings can change as more information becomes available, and a rating is a monitoring signal rather than an official government assessment.
Safety guidance for epidemic situations
- Follow official case definitions and testing guidance rather than social-media claims.
- Prioritise clean water, hand hygiene and safe food handling during any outbreak.
- Keep routine vaccinations up to date; they carry most of the protective effect.
- Seek care early if you belong to a high-risk group.
- Follow only official instructions from local authorities and emergency services — this page is a monitoring record, not an emergency alert.
Data and verification
This record was generated automatically from the World Health Organization (WHO) and de-duplicated against our archive. Early reports for any incident can be revised: locations get refined, magnitudes are recalculated and impact figures change as assessments arrive. We deliberately do not publish casualty numbers unless an official source states them. The original source report is linked at the top of this page.
