Suspected Hantavirus Infections Linked to Cruise Ship

Three individuals aboard a cruise ship in the Atlantic Ocean are believed to have succumbed to suspected hantavirus infections, according to a statement from the World Health Organization. This virus family is typically associated with rodents.

As of now, one case has been confirmed in a laboratory setting, with five other suspected cases also identified. Among the six affected individuals, three have died, and one is currently in intensive care in South Africa.

Foster Mohale, a spokesperson for South Africa’s National Department of Health, indicated that passengers from the MV Hondius, an international cruise vessel, are receiving treatment for “serious health complications” stemming from an undiagnosed acute respiratory illness.

Details on the Voyage

The MV Hondius, which had around 150 passengers from various nations, set sail from Ushuaia, Argentina, about three weeks ago. Its itinerary included stops at the Canary Islands, Antarctica, the Falkland Islands, and several other locations, Mohale noted.

In a statement, the ship’s operator, Oceanwide Expeditions, mentioned that they are closely observing the situation and ensuring that all necessary medical support is provided to both passengers and crew. Currently, the vessel is positioned off the coast of Cape Verde.

“Regrettably, three passengers have passed away during this trip,” the statement indicated. “Two deaths occurred on board, and one after disembarkation. Additionally, one passenger is being treated in Johannesburg’s intensive care unit, and two others require urgent medical assistance.”

Oceanwide has clarified that the precise cause of the infections is still under investigation. It also stated that it remains unclear whether hantavirus is directly connected to the three deaths associated with the voyage. No confirmation of hantavirus has been made for the two symptomatic individuals still on board.

Patient Details

Among the sick, a 70-year-old male passenger reported fever, headache, and other concerning symptoms. He passed away upon arrival in St. Helena Island, and authorities are awaiting arrangements for his remains to be sent back to the Netherlands.

Additionally, his 69-year-old wife fell ill during the voyage and sadly collapsed at the O.R. Tambo International Airport while trying to fly back home, where she later died after being admitted to a medical facility.

A British passenger also fell ill while traveling between St. Helena and Ascension Island and was subsequently transferred to a private medical center in Johannesburg, where he tested positive for hantavirus.

The health department is collaborating with the National Institute for Communicable Diseases and local health authorities to track contacts related to these cases.

Public Response and Expert Insights

Mr. Mohale reassured the public that there is no need for alarm, noting that only two patients from this cruise ship have entered South Africa. He mentioned that the World Health Organization is coordinating efforts with other affected nations to prevent any further spread of the disease.

Hantavirus, generally transmitted through contact with rodent droppings or urine, is not often associated with cruise ships, which are more commonly linked to illnesses like norovirus. Dr. Emily Abdoler, an expert in the field, expressed surprise at this situation, noting a lack of prior reports of hantavirus on cruise vessels.

She also speculated that the infection could have originated from rodent droppings either onboard or at a docking location, with potential transmission among passengers being a possibility.

“While hantavirus isn’t common, the idea of human-to-human transmission raises a few eyebrows,” she added, reflecting on the oddity of six infections presenting in this context.

Initial hantavirus symptoms can resemble those of the flu, which then develop into more severe respiratory issues. The disease had gained attention recently following the death of Betsy Arakawa, the wife of actor Gene Hackman.

As of the end of 2023, the Centers for Disease Control and Prevention reported 890 hantavirus cases detected since monitoring began in 1993.
