Geneva: The World Health Organization (WHO) has confirmed five cases of hantavirus infection linked to a cruise ship operating in the Atlantic, while stating that the overall risk to the general public remains “low,” according to an update from global health officials.
The cases were identified during routine medical monitoring after passengers and crew reported flu-like symptoms, including fever, fatigue, and respiratory distress. Laboratory testing later confirmed hantavirus infection in five individuals. All affected persons have been isolated and are receiving medical care.
Health authorities have launched an epidemiological investigation to determine the source of exposure onboard the vessel. Preliminary assessments suggest that the infection may be linked to contact with contaminated areas or rodent activity, though officials have not yet confirmed the exact transmission pathway.
The cruise ship has been placed under enhanced sanitation protocols, with deep cleaning and pest control measures being implemented. Passenger movement has also been restricted in certain sections of the vessel as a precautionary step.
WHO officials clarified that hantavirus does not typically spread from person to person in most strains and is generally transmitted through contact with infected rodents or their droppings. They added that isolated cases in confined environments such as ships can occur but do not usually indicate a wider outbreak risk.
Despite the confirmed cases, the WHO stressed that there is no evidence of broader community transmission and that the situation is being closely monitored in coordination with maritime health authorities and national agencies.
Passengers who were onboard the ship are being advised to monitor their health for symptoms over the coming days, while medical teams are conducting contact tracing and preventive screening where necessary.
Maritime authorities have also stepped up inspections of similar vessels operating in Atlantic routes to ensure compliance with hygiene and pest-control standards.
Public health experts note that while hantavirus infections can be severe, outbreaks remain rare and are generally contained quickly when detected early, especially in controlled environments such as cruise ships.
The WHO said it will continue to provide updates as the investigation progresses, but reiterated that the current assessment indicates a low risk to the wider public.
