Deadly Hantavirus Outbreak Strikes Atlantic Cruise: Three Dead, Others Critically Ill
Three deaths and several suspected cases of hantavirus reported on the MV Hondius cruise ship. Experts warn of a long incubation period as the vessel anchors.
Fatalities and Suspected Cases on MV Hondius
The World Health Organization (WHO) has confirmed a deadly outbreak of hantavirus aboard the MV Hondius, a polar expedition cruise ship currently anchored off the coast of Cape Verde. Three passengers have died, and several others remain in critical condition following a journey that began in southern Argentina. The vessel, operated by Oceanwide Expeditions, completed its scheduled voyage on May 4, but remains in a state of medical uncertainty as local authorities coordinate screening and disembarkation protocols.
The Victims and International Response
Among the deceased are a Dutch couple; a 70-year-old man who died upon arrival at the British territory of St Helena, and a 69-year-old woman who passed away in a Johannesburg hospital after being medically evacuated. A third Dutch national has also been confirmed dead. Currently, a 69-year-old British national is fighting for his life in intensive care in South Africa. The WHO reports one confirmed case and five suspected cases among the approximately 150 tourists and crew members on board. The UK Foreign Office has stated it is monitoring the situation closely and stands ready to support its nationals.
Understanding the Hantavirus Threat
Hantavirus is primarily a zoonotic disease, typically transmitted to humans through contact with the saliva, urine, or droppings of infected rodents. While it is known for causing severe respiratory distress and high fever, human-to-human transmission is considered exceptionally rare. The appearance of the virus on a cruise ship—an environment more commonly associated with norovirus—has raised significant concerns. Microbiologist Siouxsie Wiles noted that the long incubation period, ranging from one to eight weeks, creates a difficult monitoring window to see if more cases emerge among those who have been sharing the vessel since it departed Ushuaia on March 20.
Current Status and Quarantine Measures
The MV Hondius is currently anchored outside the capital city of Praia. Despite reports that two crew members require urgent medical care, Cape Verdean authorities have yet to grant authorization for their disembarkation to local hospitals. Oceanwide Expeditions stated they are in “close consultation” with health officials to ensure safe screening and repatriation. This incident follows a high-profile hantavirus death in 2025 involving the wife of actor Gene Hackman, which previously brought renewed global attention to the dangers of the respiratory illness.
