The hantavirus outbreak that has been causing chaos aboard a cruise ship has now made its way to Switzerland. A man infected with this rodent-transmitted illness has arrived in Zurich to receive medical care.
This development follows the refusal by the Canary Islands to allow the luxury cruise ship, MV Hondius, to dock. Authorities there are concerned about a potential outbreak within the community, particularly after the virus led to the deaths of three passengers and left several others seriously ill.
Currently, the ship finds itself stranded in the Atlantic Ocean near Cape Verde, an island nation located off the coast of West Africa. The vessel has been immobilized for several days, as health officials have previously denied docking permission in a bid to safeguard public health.
The MV Hondius was originally scheduled to dock in the Canary Islands. However, the president of the archipelago has also denied entry, leaving the future of nearly 150 passengers uncertain.
In the midst of this crisis, Swiss authorities have confirmed that a man who was a passenger on the MV Hondius has contracted the hantavirus. He is now receiving treatment in Zurich, marking the virus’s first known appearance in Switzerland from this particular outbreak.
His wife is currently not experiencing any symptoms, but has been placed in isolation ‘for safety reasons,’ local media has reported.
The Swiss development echoes the nightmare scenario envisaged by worried Canary Islands officials – that symptomless passengers could disembark, only to prove to be infected.
Authorities are investigating whether the man has had any recent contact with other people, but have assured that the risk to the general public is low.
A 56-year-old British doctor is among three patients who have just been evacuated from the MV Hondius in Cape Verde, to receive treatment at specialist hospitals ‘in Europe’, the Dutch foreign ministry confirmed.

The emergency evacuation comes after a flight scheduled to escort the British doctor – suffering with ‘acute respiratory symptoms’ – to the Canary Islands was cancelled without explanation.
The other two evacuees are a 41-year-old Dutchman and a 65-year-old German.
While the Dutchman is also presenting with ‘acute symptoms’, the German is asymptomatic but is understood to have been a close contact of a person who died on the ship on May 2.
The head of the World Health Organisation (WHO), Director-General Tedros Ghebreyesus, previously said the three patients were being evacuated to the Netherlands.
But according to Bild, the German national will be brought to a hospital in the German city of Duesseldorf for testing.
Two specialist doctors in infectious diseases are heading from the Netherlands to the MV Hondius ship, its operator said on Wednesday.
‘Two infectious disease physicians, currently en route from the Netherlands, will embark m/v Hondius and remain with the vessel after its anticipated departure from Cape Verde,’ said Oceanwide Expeditions in a statement.
These doctors would only board the ship following the successful transfer of the three patients, the operator added.
On Wednesday, the president of the Canaries, Fernando Clavijo, told COPE radio station that he had requested an ‘urgent meeting’ with the Prime Minister of Spain, Pedro Sanchez, saying that the decision to allow the cruise ship to dock on Canarian territory was not based on ‘any technical criteria’.
He added that there is ‘insufficient information to maintain a message of calm and guarantee the safety of the Canary Island population’.
Clavijo also criticised the Spanish government for its ‘institutional disloyalty’ and lack of professionalism for failing to keep him informed.
He also reproached the Minister of Health, Mónica García, for not providing him with explanations about the criteria followed by the WHO.
‘I cannot allow it to enter the Canary Islands,’ he insisted.
Earlier on Wednesday, Spanish state broadcaster TVE reported the cruise ship was set to dock at the Canary Island of Tenerife, citing sources from the country’s health ministry.

Despite the growing spat between the Canaries and the Spanish government, the ship’s operator Oceanwide Expeditions has said the archipelago is still the destination for the Hondius ‘at this stage’.
Spain’s health ministry has previously said the ship was due to arrive at the Islands in ‘three to four days’, adding that upon arrival, ‘crew and passengers will be duly examined, cared for, and transferred to their respective countries.’ It is unclear which port the ship will dock at.
The health ministry said the WHO had explained that the Canary Islands were ‘the closest place with the necessary capabilities’ medically.
Oceanwide Expeditions said its plan was for the ship to sail north ‘to the Canary Islands, either Gran Canaria or Tenerife, which will take three days of sailing’.
But Canary Islands President Clavijo is insistent on not allowing the ship to dock there, claiming neither the citizens or government ‘can rest easy because the risk to the Canarian population is clearly very real’.
‘We do not know the condition of the passengers or how many have been infected,’ he said.
The MV Hondius has been at the centre of an international health scare since Saturday, when the WHO was informed that the rare disease – usually spread from infected rodents, typically through urine, droppings and saliva – was suspected of being behind the deaths of three of its passengers.
As others fell ill, passengers and crew have been in isolation after Cape Verde authorities barred the ship from docking. The ship is anchored just off the island nation’s capital, Praia.
New footage from inside the vessel showed the ship’s decks mostly deserted, with only a few people wearing medical masks moving about.
Common spaces were empty as passengers were isolated in their cabins. At least five people with full protective gear, white overalls, boots and face masks, were seen disembarking from the ship into a small vessel.
Another video shared on social media by Turkish influencer Ruhi Çenet shows the moment the vessel’s crew told passengers someone had died.
Footage shows a crew member saying: ‘One of our passengers sadly passed away last night.’
‘I’m told by the doctor we’re not infectious. The ship is safe when it comes to that.’
But the video then cuts to Çenet telling the camera that ‘the situation was much worse than we were told,’ as he explains that a day after he left the ship, the wife of the person who had died also passed away.
‘After a third person died, it became clear that there was hantavirus on board.’
The Dutch operator Oceanwide Expeditions indicated Tuesday that a solution was in sight, with plans to evacuate the two sick crew members to the Netherlands for ‘urgent medical care’, along with the third person who had been in close contact with a German passenger who died on Saturday.
Once the evacuation takes place, MV Hondius ‘can continue its route’, Ann Lindstrand, the WHO’s representative in Cape Verde, said.

What are hantaviruses?
Hantaviruses are typically spread by rodents (file image)
Hantaviruses are a family of viruses which can cause serious illnesses and death.
They are typically spread by rodents and are not normally spread person-to-person.
The viruses can cause two syndromes – hantavirus pulmonary syndrome (HPS) and haemorrhagic fever with renal syndrome (HFRS).
Early symptoms of HPS include fatigue, fever and muscle aches.
Intensive headaches, back pain, nausea and blurred vision are symptoms of HFRS.
Minimising contact with rodents at home, in the workplace, or in a campsite can help reduce the risk of exposure to hantaviruses.
The cruise set sail from Ushuaia in Argentina on April 1 destined for Cape Verde, and counted 88 passengers and 59 crew members, with 23 nationalities onboard.
The WHO was trying to deduce how hantavirus had appeared on the ship, with the first person who died having developed symptoms on April 6.
The first stricken passenger, a 70-year-old Dutch man, died on April 11 as the ship steamed towards Tristan da Cunha.
His body remained on board until April 24, when it ‘was disembarked on St Helena, with his wife accompanying the repatriation,’ Oceanwide Expeditions said.
The man’s 69-year-old wife later felt sick on a flight from St Helena to South Africa, and she died on April 27 upon arrival at the emergency department of Johannesburg hospital.
Health officials are now trying to trace more than 80 people who were on board her flight.
On that same day, a British passenger on the cruise became ‘seriously ill and was medically evacuated to South Africa,’ the company said.
South African authorities have confirmed that the 69-year-old British patient, who is being treated in a Johannesburg hospital, tested positive for the hantavirus.
On May 2, another passenger of German nationality died on board the ship.
According to the UK Government’s hantavirus advice, symptoms typically appear between two and four weeks after exposure, but can range from two days to eight weeks, meaning illness may develop in other passengers in the coming days or weeks.
Around 40 per cent of cases result in death, according to the US Centres for Disease Control.
Early symptoms can include fatigue, fever, muscle aches and intense headaches.
They are not usually spread person-to-person and are typically only transferred via bodily fluids and close contact.

The risk of contracting the illness can be reduced through minimising contact with rodents.
Meanwhile, the UK Government is putting ‘plans in place’ for the onward travel of Britons stuck aboard the cruise ship, the Prime Minister said.
In a post on X, Sir Keir Starmer said: ‘My thoughts are with those affected by the hantavirus outbreak onboard the MV Hondius.
‘We are working closely with international partners to support British nationals on board, and we’re putting plans in place for their safe onward travel.
‘The risk to the wider public remains very low – protecting the British people is our number one priority.’
