Suspected Hantavirus Outbreak on Atlantic Cruise Ship

A suspected outbreak of hantavirus on a cruise ship in the Atlantic has resulted in three fatalities and several ill passengers, according to the World Health Organization (WHO).

The WHO reported one confirmed case of hantavirus and five additional suspected cases. Among the six affected individuals, three have died, while one remains in intensive care in South Africa.

As part of its response, the WHO is working with government officials and the cruise operators to facilitate the medical evacuation of two passengers exhibiting symptoms, and they are also assessing the overall public health risk for those still onboard.

“Comprehensive investigations are underway, including further clinical testing and epidemiological studies,” the WHO stated. “Passengers and crew are receiving necessary medical care, and the virus is currently being sequenced.”

The outbreak is tied to the M/V Hondius, a Dutch-flagged cruise ship operating off the coast of West Africa.

Oceanwide Expeditions, which runs the vessel, confirmed the unfortunate deaths of three passengers during the journey and noted that one passenger requires intensive care in Johannesburg. Additionally, two crew members received emergency treatment.

As of late Sunday, Cape Verde authorities had not permitted symptomatic passengers to disembark for further medical evaluation, which has raised concerns. Local health officials have boarded the ship to evaluate the situation, but the transfer of symptomatic individuals to shore facilities is still pending approval.

Oceanwide Expeditions emphasized that ensuring timely medical care for the two symptomatic passengers onboard is a top priority.

Meanwhile, the Dutch authorities are coordinating efforts for the repatriation of those affected, though this is contingent on local approvals. Hantavirus infections typically arise from contact with the urine or feces of infected rodents and can lead to severe respiratory issues.

While such infections are rare, the WHO noted that there’s potential for person-to-person transmission, which necessitates vigilant monitoring and support. Although no specific treatment exists for this virus, initiating early care can enhance survival rates.

The WHO has communicated with global health entities according to international regulations and will continue to offer support in response to the outbreak. Oceanwide Expeditions stated that they are in the process of establishing the complete situation and determining the subsequent steps for medical and testing needs.
