Hantavirus Outbreak On Cruise Ship 3 Deaths Reported

Health authorities are investigating a suspected hantavirus outbreak aboard a cruise ship in the Atlantic Ocean after three passengers died and several others became seriously ill. The outbreak was reported on the Dutch-operated expedition cruise ship MV Hondius, which was traveling from South America toward the Canary Islands when multiple passengers began showing severe respiratory symptoms. The World Health Organization (WHO) confirmed that at least two hantavirus infections have been laboratory confirmed, while several additional cases remain under investigation.

According to the WHO, seven people aboard the vessel were either confirmed or suspected to have contracted the virus as of this week. Three of those infected later died, while another passenger remains in critical condition in a hospital in South Africa. Several others on the ship have reported fever, breathing difficulties, and gastrointestinal symptoms. Health officials are continuing medical monitoring and testing passengers and crew members onboard.

The first reported victims included a Dutch couple who had boarded the ship after traveling through parts of Argentina and South America. The 70-year-old man became ill during the voyage and later died after being taken off the ship at Saint Helena Island. His wife also became seriously ill and later died after being flown to Johannesburg, South Africa, for emergency treatment. A third passenger, identified as a German national, also died after developing pneumonia-like symptoms aboard the vessel.

Medical experts believe the outbreak may involve the Andes strain of hantavirus, which is extremely rare because it can spread from person to person under close-contact conditions. Most hantavirus infections are usually transmitted through contact with rodent urine, saliva, or droppings. However, WHO officials said limited human-to-human transmission may have occurred among passengers sharing cabins or spending long periods together on the ship.

The MV Hondius was reportedly carrying around 150 passengers and crew members from multiple countries. Authorities in Cape Verde initially prevented passengers from leaving the ship while investigations continued. Medical teams later boarded the vessel wearing protective equipment to examine symptomatic individuals and collect laboratory samples. International health agencies are now coordinating efforts to trace contacts and manage possible exposure risks.

WHO officials stressed that the overall risk to the general public remains low despite concerns surrounding the outbreak. The organization said hantavirus infections are rare and outbreaks involving possible human transmission are uncommon. However, experts warned that cruise ships create challenging conditions for infection control because of close living spaces and shared facilities.

Oceanwide Expeditions, the company operating the ship, said emergency response procedures were immediately activated after passengers became ill. Isolation measures, health monitoring, and deep cleaning operations were introduced onboard as authorities worked to prevent further spread. Reports also said some crew members developed symptoms and remain under observation.

The incident has raised fresh concerns about disease outbreaks aboard cruise ships, years after the global COVID-19 pandemic exposed the difficulties of controlling infections at sea. Public health experts say the situation highlights the importance of rapid international coordination, early testing, and strong onboard medical response systems during health emergencies.

Investigations are continuing to determine exactly how the virus entered the ship and whether passengers were infected before boarding or during the voyage itself. WHO officials said further laboratory testing and virus sequencing are ongoing, while passengers and crew continue to remain under medical supervision as the ship awaits clearance for safe disembarkation.
