Hantavirus Outbreak on Atlantic Cruise Ship Leaves Three Dead, WHO Monitoring Situation

Geneva — The World Health Organization (WHO) has confirmed it is closely monitoring a serious public health incident aboard a cruise ship in the Atlantic Ocean, where a hantavirus outbreak has resulted in three deaths and multiple suspected infections.

According to WHO, one case has been laboratory confirmed, while five others are currently under investigation. Of the six individuals affected, three have died and one is in critical condition, receiving intensive care in Johannesburg.

The outbreak has occurred on the MV Hondius, an expedition cruise vessel operated by Oceanwide Expeditions. The ship began its journey from Ushuaia on March 20 and was scheduled to conclude its voyage in Cape Verde on May 4.

WHO stated that detailed epidemiological investigations and laboratory testing are ongoing, including genetic sequencing of the virus. Medical teams are providing care and support to both passengers and crew onboard.

Hantavirus is a rare but potentially life-threatening disease, typically transmitted to humans through contact with rodent urine, droppings, or saliva. It can lead to severe respiratory complications and requires close medical supervision. Human-to-human transmission is uncommon but not impossible in certain strains.

Among the affected is a 69-year-old British national currently being treated in South Africa. WHO is coordinating with relevant countries and the ship’s operators to arrange medical evacuation for symptomatic passengers and to conduct a comprehensive risk assessment for those still onboard.

The agency has activated international coordination mechanisms under global health regulations and plans to release a detailed outbreak report for public awareness.

Officials have acknowledged swift cooperation between authorities and the cruise operator, which has been crucial in managing the evolving situation and limiting further risk.
