Newswise — An international consortium including UNIGE and HUG has clarified the origin and mode of transmission of the Andes virus, which spread aboard a cruise ship in spring 2026.[1]
Key Facts

The Threat
An international collaboration involving the University of Geneva (UNIGE) and the Geneva University Hospitals (HUG) has confirmed that the hantavirus outbreak aboard the M/V Hondius in April 2026 stemmed from an initial infection acquired on land, followed by person-to-person transmission on board.[1]
Genetic analyses show that the virus belongs to a natural lineage of the Andes virus circulating in Argentine Patagonia. Published in Science, these findings highlights the vital role of scientific cooperation in responding to global health emergencies.[1]
In April 2026, an outbreak of severe respiratory infections, presenting as hantavirus pulmonary syndrome (HPS), was detected aboard the cruise ship M/V Hondius, which had left Ushuaia, Argentina, on 1 April.[1]
Centers for Disease Control and Prevention | CDC (.gov) says: We demonstrated that pet rats, previously confirmed to be Seoul orthohantavirus–infected and involved in human infections in Germany, were concurrently infected with rat hepatitis E virus. In Germany, pet rats have been linked to 4 detections of cases of human SEOV infection (5,8,9).[2]
Transmission Method
What the reports say about exposure and spread: Two questions remained unanswered: how did the virus spread on board, and where did the infection originate? This far exceeds the maximum known incubation period for initial infection from rodents, estimated at six weeks.[1]
How hantavirus spreads, according to the World Health Organization: Hantaviruses reach people through contact with the urine, droppings or saliva of infected rodents, and less often through rodent bites. Only the Andes virus, in South America, has been documented spreading between people, and only rarely, after close and prolonged contact.[3]
Affected Regions
Places named in the reports: Argentina, Germany.
Holistic & Immune Defense Outlook
There is no herb, supplement or diet that has been shown to prevent or cure hantavirus. There is no licensed antiviral treatment or vaccine for hantavirus. Care is supportive, and early access to intensive care improves survival. If you have symptoms after a possible exposure, the most important step is to see a clinician quickly and tell them where you have been.
The World Health Organization’s protective steps for this disease:
- Keep homes and workplaces clean, and seal openings rodents can get through.
- Dampen areas contaminated by rodents before cleaning them; do not dry-sweep or vacuum droppings.
What a whole-body approach can do is keep your baseline strong, so your body is better able to respond when it meets any infection. The basics have the best evidence behind them: steady sleep, a diet rich in vegetables, fruit, beans and whole grains, enough water, regular movement, and keeping routine vaccinations current.
