A suspected hantavirus outbreak aboard the Dutch cruise ship MV Hondius has killed three people and sickened dozens of others [1, 2].
The incident highlights the risks of rodent-borne pathogens in confined environments and the challenges of managing medical emergencies in remote maritime locations.
The ship was positioned off the coast of Cape Verde, West Africa, when the outbreak was reported on Monday, June 10, 2024 [1, 5]. There were approximately 150 people on board, including 17 Americans and four Canadians [1, 3, 4].
Health officials believe the illness was caused by hantavirus, which is typically transmitted to humans via rodents [1, 6]. The exact source of the infection on the vessel remains under investigation.
"We have confirmed three deaths among passengers, all of whom tested positive for hantavirus," said Dr. James O'Leary of the World Health Organization's regional office [7].
Emergency measures were implemented to stabilize the remaining passengers and crew. Some individuals required urgent transport to land-based facilities for specialized care.
"Two patients are being evacuated to a hospital on the mainland for treatment," said a health ministry spokesperson in a statement to Radio-Canada [8].
Local authorities in Cape Verde are coordinating with the ship's operators to manage the crisis and prevent further spread of the virus. The effort involves both medical triage, and environmental assessments of the ship's interior.
"We are working closely with Cape Verde health authorities to determine the source of the infection and to provide medical care to those affected," said Dr. Maria Silva, a spokesperson for the Cape Verde Ministry of Health [9].

Hantaviruses are rare but severe respiratory diseases typically linked to exposure to rodent droppings or urine. An outbreak on a cruise ship is highly unusual and suggests a significant breach in pest control or a localized environmental contamination. Because the virus is not known to spread from person to person, the focus of the investigation will likely center on the ship's sanitation and food storage areas.
