An alarming outbreak of hantavirus has emerged from the MV Hondius cruise ship, with authorities confirming cases among both US and French nationals who recently returned home. The World Health Organization (WHO) has reported a total of seven confirmed cases associated with the vessel, raising concerns about the potential for further transmission.
Details of the Outbreak
The situation unfolded after passengers disembarked the MV Hondius in Tenerife, Spain. Reports indicate that both an American and a French citizen have tested positive for the virus, with a second American also displaying mild symptoms upon repatriation. This precautionary measure saw the affected individuals transported in “biocontainment units,” highlighting the seriousness of the health risk involved.
French Health Minister Stéphanie Rist confirmed that a woman in Paris is currently isolating and her condition is worsening, prompting health officials to trace 22 contacts. Tragically, three passengers have succumbed to illness after travelling on the cruise, with two confirmed to have contracted hantavirus. The WHO noted that the initial case, believed to be the source of the outbreak, died before a test could confirm the virus.
Ongoing Monitoring and Safety Measures
As investigations continue, two British nationals diagnosed with hantavirus are receiving treatment in the Netherlands and South Africa. Hantaviruses, which are primarily spread by rodents, can be transmitted to humans, particularly through the Andes strain that appears to have affected passengers during their travels in South America.

Symptoms of this virus include fever, severe fatigue, muscle aches, gastrointestinal distress, and respiratory difficulties. Officials have assured the public that the risk of a widespread outbreak remains low, despite the concerning circumstances.
In total, over 90 passengers from the MV Hondius are being repatriated, with Spanish authorities stating that 54 individuals, including crew members and passengers, remain aboard the ship. Mónica García, Spain’s Health Minister, indicated that six passengers, comprising four Australians, a Briton, and a New Zealander, are still on board. Additional evacuation flights are being organised to ensure the safe return of all affected individuals.
International Response and Precautions
In the wake of these developments, the US Department of Health and Human Services has announced that all 17 American citizens on a recent flight from the ship will undergo thorough clinical assessments in Nebraska. Meanwhile, a British national residing in the US was also repatriated alongside these individuals. Seven other US passengers have returned to their home states, where they will be closely monitored for any symptoms.
As the situation unfolds, WHO’s Director-General, Tedros Adhanom Ghebreyesus, expressed concerns about the US’s decision not to follow specific guidelines regarding the outbreak, warning that it could pose risks. The WHO has recommended a 42-day isolation period for individuals departing the MV Hondius, a measure that Dr. Jay Bhattacharya, acting head of the US Centers for Disease Control (CDC), has suggested is important, although he cautioned against inciting public panic.
Cruise passengers have been seen donning protective gowns, bouffant caps, and masks as they disembarked at the port of Grandilla de Abona in Tenerife. In the UK, 20 British nationals arrived at Manchester Airport from Tenerife on a chartered flight and were taken to Arrowe Park Hospital in Wirral, where they will isolate for 72 hours. Thus far, none have reported any symptoms.
The Human Cost
The implications of this outbreak extend beyond mere statistics. Among the deceased is an elderly Dutch man who was the first passenger to die on board the MV Hondius on April 11. Despite exhibiting symptoms, he was classified as a probable case as he did not undergo testing. His wife, who left the ship on April 24, tragically passed away shortly thereafter in South Africa. Another confirmed case involved a German woman who died aboard the ship on May 2.

The MV Hondius had embarked on its journey from Ushuaia, Argentina, on April 1 and is currently docked in Tenerife’s Grandilla port. The captain of the vessel, Jan Dobrogowski, conveyed his thoughts to those who have lost their lives, acknowledging the profound challenges faced by the crew and passengers over the past weeks.
Why it Matters
This outbreak serves as a stark reminder of the vulnerabilities associated with global travel and the interconnectedness of health risks. As nations respond to the hantavirus cases linked to the MV Hondius, the situation underscores the critical importance of effective monitoring and rapid response measures to prevent further outbreaks. The collective vigilance of health authorities, coupled with public awareness and preparedness, will be essential in navigating the complexities of emerging infectious diseases in an increasingly globalised world.
