Cruise Ship Hantavirus Outbreak Leaves Three Dead Aboard MV Hondius in the Atlantic

A serious cruise ship hantavirus outbreak has shocked the travel and health world after three people lost their lives aboard the MV Hondius, a polar cruise ship sailing across the Atlantic Ocean. The World Health Organization has confirmed the alarming development to the BBC, raising fresh concerns about the spread of the rare and potentially deadly virus among passengers and crew.

WHO Confirms Cases on Board

According to the WHO, the MV Hondius has reported one confirmed case and five suspected cases of hantavirus. The vessel was on a long journey from Argentina to Cape Verde when the outbreak began affecting people aboard. Health officials are now closely monitoring the situation as more details continue to emerge.

A 69-year-old UK national is among those affected and is currently being treated in intensive care in Johannesburg, South Africa. Local authorities have confirmed to the BBC that he tested positive for the virus. The UK Foreign Office has stated that it is keeping a close watch on the situation and is prepared to assist any British nationals who may need help.

What Is Hantavirus?

Hantavirus is a rare but serious illness that is most commonly passed to humans through contact with rodents. Infection usually happens when people come into contact with rodent droppings, saliva, or urine. In some cases, breathing in dust contaminated with these substances can also lead to infection.

The virus can cause severe respiratory illness, and although it is rarely passed from person to person, it has been known to spread in unusual situations. The current outbreak on a cruise ship has raised questions about how the virus may have entered such a controlled environment in the first place.

The MV Hondius Journey

The MV Hondius is operated by the tour company Oceanwide Expeditions. According to the company’s website, the ship left Ushuaia in southern Argentina on 20 March and completed its long journey on 4 May in Cape Verde, where it is currently anchored outside the capital city of Praia.

The vessel is a 107.6 meter polar cruise ship designed to carry up to 170 passengers in 80 cabins. It is also crewed by 57 staff members, 13 guides, and one onboard doctor. Foster Mohale, a spokesperson for South Africa’s health ministry, told the BBC that there were around 150 tourists on board, coming from various countries.

The Tragic Loss of Lives

Before the WHO officially confirmed the three deaths, Mohale had earlier told the BBC that at least two people had passed away. He revealed that one of those who died was a 70-year-old Dutch man, while the second was a 69-year-old Dutch woman. The two were reportedly a married couple.

The man fell ill suddenly during the voyage, experiencing severe symptoms that included fever, headache, abdominal pain, and diarrhoea. He died upon arriving at St Helena, a British territory located in the South Atlantic. His wife also became sick during the trip and was evacuated to South Africa, where she later died in a hospital in Johannesburg.

The third confirmed victim was also Dutch. Efforts are now underway to repatriate the body, along with a fellow guest who was closely connected to the deceased. Oceanwide Expeditions has expressed its condolences and is working closely with health authorities to manage the situation responsibly.

Crew Members Also Affected

In addition to the three deaths, two crew members on board have reportedly been in urgent need of medical care. However, authorities in Cape Verde have not yet authorized their disembarkation, meaning they remain on the ship until officials grant permission for them to access proper hospital treatment.

Oceanwide Expeditions has stated that the disembarkation and medical screening of all guests must be carefully coordinated with local health authorities. The company is currently in close consultation with the relevant officials to determine the best path forward for both passengers and crew.

Concerns About Further Spread

Microbiologist Siouxsie Wiles, who spoke with the BBC, raised important concerns about the possibility of more cases appearing in the coming days or weeks. She explained that the incubation period for hantavirus can range anywhere from one to eight weeks, meaning some passengers and crew members may not yet show symptoms even if they have been exposed.

This long incubation period creates a unique challenge for health authorities trying to contain the outbreak. As people who were on the ship return to their home countries, the risk of new cases emerging in different parts of the world remains a serious concern.

Hantavirus Returns to the Spotlight

The current outbreak has brought hantavirus back into the public eye, especially after a tragic case last year captured global attention. In March 2025, the wife of Oscar-winning actor Gene Hackman passed away from a respiratory illness linked to hantavirus. That incident raised public awareness about how dangerous and unpredictable the virus can be, even in environments where exposure may seem unlikely.

What Cruise Passengers Should Know

While cruise ship hantavirus outbreaks are extremely rare, this incident highlights the importance of strict hygiene and health protocols on board long-distance voyages. Travelers planning future cruises are encouraged to follow basic safety steps such as keeping personal cabins clean, washing hands regularly, and reporting any unusual symptoms to onboard medical staff immediately.

For those who have recently traveled aboard the MV Hondius or other ships in the same region, health experts recommend monitoring their health closely for at least eight weeks. Symptoms to watch for include fever, fatigue, body aches, headaches, abdominal pain, and breathing difficulties. Anyone experiencing these signs should seek medical care as soon as possible and inform doctors about their recent travel history.

Final Thoughts

The cruise ship hantavirus outbreak aboard the MV Hondius has shaken the travel community and reminded the world how easily serious illnesses can spread, even in unexpected environments. With three confirmed deaths, multiple suspected cases, and ongoing investigations by health authorities, the coming weeks will be critical in determining how widespread the outbreak truly is. Passengers, crew members, and global health officials are now working closely to manage the situation, while travelers everywhere are reminded of the importance of preparedness, awareness, and caution during international voyages.
