Three Dead as Authorities Identify Two Possible Causes of Hantavirus Outbreak on Cruise Ship
A troubling situation is unfolding at sea as the MV Hondius cruise ship faces a suspected hantavirus outbreak that has already claimed three lives. Out of 147 passengers and crew on board, seven individuals have been reported ill, with two of those cases now confirmed as hantavirus. The ship is currently positioned off the coast of Cape Verde, with passengers confined to their cabins while disinfection and public health measures are being carried out. The World Health Organization has assessed the overall risk to the global population as low, but investigators are working urgently to determine how the outbreak began.
Hantavirus is primarily spread through contact with infected rodents, specifically through their urine, saliva, or droppings. When WHO official Dr. Maria Van Kerkhove addressed the situation on May 5, she noted that authorities had been told there were no rats on board the ship. However, she pointed out that the cruise had made stops at several different islands during its voyage, some of which are known to have rodent populations. This led her to suggest that exposure may have occurred during one of those port visits rather than on the vessel itself.
The second possible explanation involves a rarer form of transmission that has health officials paying extra attention. Physician Zaid Fadul highlighted that the specific strain believed to be involved, the Andes virus, is notable for its documented ability to pass from person to person. The ship originally departed from Argentina, a region where this particular strain of hantavirus has previously been found. Fadul stated that this fact is the source of much of the anxiety surrounding the current outbreak, since human-to-human spread makes containment significantly more complicated.
Dr. Van Kerkhove confirmed that investigators do believe some human-to-human transmission may be occurring among individuals who have been in very close contact with one another. The WHO’s working hypothesis is that there are likely a couple of different transmission routes happening at the same time. Van Kerkhove also noted that the first person to fall ill is believed to have contracted the virus before even boarding the ship, adding another layer of complexity to the investigation.
The two confirmed hantavirus cases are a Dutch woman who passed away on April 27 and a 69-year-old British national whose condition is reportedly improving. The Dutch woman’s husband also died on April 11, though his case has not been confirmed as hantavirus. One patient is currently receiving intensive care at a hospital in South Africa and is said to be getting better, while two others still on board are being prepared for medical evacuation to the Netherlands for treatment. Van Kerkhove also shared that at least one other suspected case is currently asymptomatic and doing well overall.
Hantavirus can lead to two serious and potentially life-threatening conditions known as Hantavirus Pulmonary Syndrome and Hemorrhagic Fever with Renal Syndrome, both of which require prompt medical attention. UK Prime Minister Keir Starmer addressed the situation publicly, assuring people that the risk to the wider public remains very low and that protecting British nationals is the government’s top priority. The UK is reportedly putting plans in place to assist British passengers with onward travel once they are safely off the vessel, as there are approximately 19 British nationals listed as passengers alongside four British crew members on board.
As this outbreak continues to develop, global health authorities are watching closely and urging people not to panic. The situation on the MV Hondius is a stark reminder that infectious diseases can emerge in the most unexpected places, and that a swift, coordinated response is absolutely critical. Officials are focused on getting those who need care to safety as quickly as possible while keeping a close eye on everyone still on board.
