Hantavirus Outbreak on Cruise Ship: 3 Dead, WHO Confirms Suspected Cases
May 4, 2026 — A suspected hantavirus outbreak aboard the cruise ship MV Hondius, sailing from Argentina to Cape Verde, has resulted in three deaths and multiple illnesses, according to the World Health Organization (WHO) and health officials. The ship, operated by Oceanwide Expeditions, has been anchored off Praia, Cape Verde, since May 4, as local authorities coordinate medical evacuations and screenings.
Key Developments: Confirmed Cases, Evacuations and Ongoing Investigations
The WHO reported one confirmed case and five suspected cases of hantavirus infection aboard the ship. Three passengers have died, including a Dutch couple and one additional Dutch national. A British national, aged 69, remains in intensive care in Johannesburg, South Africa, after being evacuated with symptoms consistent with hantavirus infection.
South Africa’s health ministry spokesperson, Foster Mohale, confirmed that two of the deceased were a Dutch couple, aged 70 and 69. The man died after developing fever, headache, abdominal pain, and diarrhoea
while the ship was en route to St Helena, a British territory in the South Atlantic. The woman was evacuated to South Africa and died in a Johannesburg hospital. The third fatality was also Dutch, and efforts are underway to repatriate their body along with another passenger closely associated
with them, according to Oceanwide Expeditions.
The cruise ship, which departed from Ushuaia, Argentina, on March 20, has a capacity for 170 passengers and 57 crew members. Oceanwide Expeditions stated that two crew members also required urgent medical care, though Cape Verde authorities have not yet authorized their disembarkation for treatment.
What Is Hantavirus?
Hantaviruses are a family of viruses primarily spread by rodents through their urine, feces, or saliva. Human infections can lead to severe respiratory illnesses, including hantavirus pulmonary syndrome (HPS), which can be fatal if untreated. The incubation period ranges from one to eight weeks, meaning symptoms may not appear immediately after exposure.
According to the Centers for Disease Control and Prevention (CDC), early symptoms of HPS include fever, fatigue, muscle aches, headaches, and gastrointestinal issues
. The disease can rapidly progress to respiratory failure, requiring intensive care and mechanical ventilation.
Transmission and Prevention
Hantavirus is not typically spread from person to person, though rare cases of human-to-human transmission have been documented, particularly with the Andes virus strain. The primary risk factors include:
- Exposure to rodent droppings, urine, or nesting materials
- Inhaling airborne particles from contaminated environments
- Close contact with infected rodents or their secretions
The CDC recommends sealing up
homes to prevent rodent entry, trapping up
rodents safely, and cleaning up
potential contamination sites with disinfectants. Preventative measures include:
- Using gloves and masks when cleaning areas with rodent droppings
- Avoiding vacuuming or disturbing rodent nests, which can aerosolize the virus
- Keeping food stored in sealed containers to deter rodents
Treatment and Prognosis
There is no specific antiviral treatment for hantavirus infections. Treatment focuses on supportive care
, including hospitalization, intravenous fluids, and respiratory support for severe cases. Early recognition and immediate medical intervention improve survival rates, according to the Mayo Clinic.
Patients with severe symptoms require intensive care, including mechanical ventilation. The prognosis depends on the speed of diagnosis and the availability of critical care resources.
Ongoing Response and Next Steps
The cruise ship remains anchored in Cape Verde as local health authorities conduct medical screenings and coordinate evacuations. Oceanwide Expeditions has stated that disembarkation and medical screening of all guests require coordination with local health authorities
, and they are working closely with officials to ensure a safe resolution.
The UK Foreign Office has confirmed it is monitoring the situation and stands ready to support British nationals affected by the outbreak. The WHO continues to monitor the situation and provide updates as more information becomes available.
Key Takeaways
