Hantavirus outbreak kills 3 aboard Atlantic cruise ship, 1 critical: WHO monitoring
Synopsis
A hantavirus outbreak aboard the MV Hondius in the Atlantic Ocean has claimed three lives, with one patient in intensive care in South Africa. The WHO is coordinating emergency medical evacuations and public health assessments for 150 passengers and crew. With one confirmed case and five suspected, the outbreak highlights the disease's rare human-to-human transmission risk in confined spaces.
Key Takeaways
Three deaths confirmed from a hantavirus outbreak aboard the MV Hondius cruise ship in the Atlantic Ocean .
One laboratory-confirmed case and five suspected infections among approximately 150 passengers and crew.
A 69-year-old British national is currently in intensive care in Johannesburg, South Africa .
The WHO is coordinating medical evacuation of two symptomatic passengers and conducting full public health risk assessments.
Hantavirus typically spreads via contact with infected rodent urine or faeces; human-to-human transmission is rare but possible.
The World Health Organization (WHO) on Monday confirmed a hantavirus outbreak aboard the MV Hondius cruise vessel sailing in the Atlantic Ocean, with three deaths and one patient in intensive care in Johannesburg, South Africa. The polar expedition ship, operated by Oceanwide Expeditions and carrying approximately 150 passengers, has recorded one laboratory-confirmed case and five suspected infections among those aboard.
The vessel and its journey
The MV Hondius, a 107.6-metre expedition cruise vessel designed to carry up to 170 passengers, departed Ushuaia in southern Argentina on 20 March bound for Cape Verde. The ship houses 80 cabins, accommodating passengers, crew, guides, and an onboard doctor. According to its itinerary, the voyage was scheduled to conclude on 4 May.
Clinical status and medical response
Among the affected is a 69-year-old British national currently receiving intensive care in Johannesburg. The WHO is coordinating with member states and ship operators for the medical evacuation of two symptomatic passengers and conducting a comprehensive public health risk assessment for all remaining passengers and crew. Detailed laboratory testing and epidemiological investigations are underway, with viral sequencing ongoing.
Understanding hantavirus transmission
Hantavirus is typically transmitted to humans through contact with infected rodent urine or faeces. The disease can cause severe respiratory illness and, in rare instances, spread between humans. It is considered a serious pathogen requiring close medical monitoring and intensive supportive care. This outbreak aboard a confined cruise vessel presents elevated transmission risk due to close quarters and shared ventilation systems.
WHO coordination and next steps
The WHO has informed national focal points under the International Health Regulations and will issue a Disease Outbreak News report for public dissemination. The organisation commended the rapid coordination and actions of member states and ship operators. Full public health risk assessment and medical support continue for all individuals aboard, with further updates expected as investigations progress.
Point of View
But the presence of one laboratory-confirmed case and five suspected infections underscores the disease's unpredictability in closed environments. The evacuation of symptomatic passengers is critical, as is transparent communication with remaining passengers and crew about exposure risk and monitoring protocols.

A 69-year-old British national is among the affected individuals and is currently receiving intensive care in Johannesburg, South Africa. Authorities are providing medical support and coordinating evacuation as needed.
What is the WHO doing to contain the outbreak?
The WHO is coordinating with member states and ship operators for medical evacuation of symptomatic passengers, conducting full public health risk assessments, and providing medical support. The organisation is also facilitating viral sequencing and epidemiological investigations, with a Disease Outbreak News report forthcoming.
When did the MV Hondius depart and where was it headed?
The MV Hondius departed Ushuaia in southern Argentina on 20 March 2024 and was scheduled to arrive in Cape Verde on 4 May. The ship carried approximately 150 passengers and operates as a polar expedition cruise vessel.
