Two Dutch Nationals Die on Cruise Ship: Hantavirus Suspected

Three Dead in Suspected Hantavirus Outbreak on Atlantic Cruise Ship; Dutch Couple Among Victims

Three people have died after a suspected hantavirus outbreak aboard an Atlantic cruise ship, the World Health Organization (WHO) confirmed today. Among the victims were a Dutch couple, a 70-year-old man and a 69-year-old woman, whose deaths were linked to severe respiratory illness while traveling on the MV Hondius, a vessel sailing from Argentina to Cape Verde. The outbreak has raised alarms about the transmission of hantavirus—a rare but potentially fatal disease spread primarily by rodents—and has prompted international health authorities to intervene.

The MV Hondius, operated by Oceanwide Expeditions, departed from Ushuaia, Argentina, on March 20, 2026, with 170 passengers and 57 crew members on board. The ship was en route to Cape Verde when the outbreak was detected. According to the WHO, one case of hantavirus has been confirmed, while five additional cases remain under investigation. A UK national, aged 69, is currently in intensive care in Johannesburg, South Africa, after testing positive for the virus.

Hantavirus is typically transmitted to humans through contact with urine, feces, or saliva of infected rodents. Symptoms often begin with flu-like illness, including fever, headache, and abdominal pain, and can rapidly progress to severe respiratory distress, according to the U.S. Centers for Disease Control and Prevention (CDC). Rarely, the virus can spread between people, though direct transmission is uncommon.

Key Details of the Outbreak

The Dutch couple, aged 70 and 69, were the first confirmed fatalities. The man developed symptoms—fever, headache, abdominal pain, and diarrhea—while on board and died upon arrival at St Helena, a British territory in the South Atlantic. His partner also fell ill and was evacuated to South Africa, where she later died in a Johannesburg hospital. A third fatality, still aboard the ship, was reported by AFP, citing an anonymous source. Two additional passengers remain critically ill and are being considered for medical evacuation to Cape Verde or Spain’s Canary Islands.

South Africa’s health ministry spokesperson, Foster Mohale, told the BBC that the outbreak had affected passengers from multiple countries, with around 150 tourists on board. The WHO is coordinating with member states and the ship’s operators to conduct a full public health risk assessment, support medical evacuations, and ensure the safety of those still onboard.

What Is Hantavirus and How Is It Spread?

Hantavirus is a family of viruses found worldwide, primarily carried by rodents such as rats, mice, and voles. In the Netherlands, three types of hantaviruses are known to circulate: Puumala virus (from bank voles), Seoul virus (from rats), and Tula virus (from field mice), according to the Dutch National Institute for Public Health and the Environment (RIVM). While most infections are mild, some strains—such as those causing hantavirus pulmonary syndrome (HPS)—can be fatal if untreated.

Transmission typically occurs through inhalation of aerosolized virus particles from rodent urine, feces, or saliva. Rarely, person-to-person transmission has been documented, particularly in healthcare settings or among close contacts of infected individuals. The CDC notes that early symptoms—fever, chills, muscle aches, and fatigue—can mimic other respiratory illnesses, making diagnosis challenging without specific testing.

Hantavirus pulmonary syndrome (HPS) is a rare but severe respiratory disease that can lead to life-threatening lung and heart problems. Early symptoms resemble the flu, but the illness can progress rapidly.

International Response and Next Steps

The UK Foreign Office has confirmed This proves monitoring the situation and stands ready to assist British nationals affected by the outbreak. The WHO is working with local health authorities to ensure proper containment measures, including isolation of infected passengers and disinfection protocols aboard the ship. The MV Hondius is expected to continue its journey to Cape Verde, with plans to disembark critically ill passengers in the Canary Islands.

Dutch authorities have not yet confirmed the nationalities of all victims, but the RIVM (Dutch National Institute for Public Health and the Environment) has issued guidance on hantavirus prevention, emphasizing the importance of rodent control and avoiding contact with potentially infected animals. Travelers returning from affected regions are advised to seek medical attention if they develop flu-like symptoms within weeks of exposure.

What Travelers Should Know

For those planning to travel to regions where hantavirus is a risk—particularly areas with high rodent populations—health experts recommend:

• Avoiding contact with rodents and their droppings, urine, or saliva.
• Sealing food in rodent-proof containers and keeping living areas clean.
• Seeking prompt medical attention if flu-like symptoms develop after potential exposure.
• Following local health advisories and cruise ship protocols during outbreaks.

Cruise lines are required to report outbreaks of infectious diseases to health authorities, and passengers are encouraged to cooperate with medical screenings and isolation measures if recommended.

Next Steps and Updates

The WHO will continue to provide updates on the outbreak as more information becomes available. The Dutch Ministry of Foreign Affairs has not yet confirmed the nationalities of all victims, but travelers with concerns are advised to check official advisories from their government’s health or foreign affairs department. The MV Hondius is expected to arrive in Cape Verde on May 4, 2026, with further developments pending medical evaluations and public health assessments.
