The World Health Organization (WHO) is investigating a suspected hantavirus outbreak linked to a cruise ship travelling in the Atlantic Ocean, after multiple deaths and infections were reported among passengers.
The agency said one case has been laboratory confirmed, while five additional infections are still classified as suspected. Of the six affected individuals, three have died and one is receiving intensive care in South Africa.
What is hantavirus?
Hantavirus is a virus found worldwide and is typically transmitted to humans through contact with urine, droppings, or saliva from infected rodents such as mice and rats.
According to the US Centers for Disease Control and Prevention, symptoms usually develop after an incubation period of one to eight weeks. Early signs include sudden flu-like illness, high fever, severe muscle aches, fatigue, and headaches.
In some cases, the infection can develop into hantavirus pulmonary syndrome, a severe and potentially fatal lung condition. There is currently no specific cure, but early medical intervention can improve survival chances.
WHO confirms ongoing investigation
The WHO said it is actively supporting public health authorities in managing the situation involving the cruise vessel.
In a statement shared on X (formerly Twitter), the agency confirmed ongoing laboratory testing and monitoring of suspected cases.
Cases linked to cruise voyage
Reports indicate that the outbreak occurred during a cruise journey in the Atlantic, with passengers developing symptoms while travelling between multiple stops, including remote island locations.
A Dutch Foreign Ministry spokesperson confirmed the deaths of two Dutch nationals linked to the incident but did not release further details.
Health authorities monitoring situation
Global health officials continue to investigate the source of the outbreak and how the virus may have spread onboard the vessel.
The situation remains under review as authorities await further confirmation from ongoing laboratory analysis and epidemiological tracing.
