Passengers evacuated to the United Kingdom following a hantavirus outbreak aboard the cruise ship MV Hondius are expected to begin leaving hospital isolation after completing an initial 72-hour monitoring period, health officials have confirmed.
The passengers and crew have been isolating at Arrowe Park Hospital since arriving in Britain earlier this week after being repatriated from the Canary Islands following the outbreak onboard the Dutch-operated expedition vessel.
Authorities said those leaving the hospital will still be required to continue isolating for a further 42 days at home or at alternative accommodation under ongoing monitoring by UK health officials.
The outbreak has already resulted in three deaths and triggered an international public health response involving multiple countries, quarantine operations and repatriation flights.
Health authorities continue to stress that the risk to the wider public remains low, although surveillance and monitoring efforts remain in place as investigations continue into the spread of the virus.
Passengers Complete Initial Isolation Period
The group isolating at Arrowe Park Hospital includes 20 British nationals, one German citizen who resides in the UK and one Japanese passenger.
The facility previously served as Britain’s first Covid quarantine site during the coronavirus pandemic and has once again been activated for infectious disease containment measures.
Officials said the passengers have spent the past several days in self-contained accommodation units where they received food, healthcare monitoring and welfare support from NHS and UK Health Security Agency teams.
Although 22 people are technically eligible to leave the facility, authorities indicated that not everyone would immediately return home because some living arrangements may not be suitable for continued isolation.
Passengers living in shared homes or apartment buildings could instead be transferred to alternative accommodation to minimise any potential risk of exposure to others.
UK Health Authorities Continue Monitoring
The UK Health Security Agency said the additional isolation period remains precautionary because hantavirus infections can develop over an extended incubation period.
Public health officials stated that passengers will continue receiving daily monitoring and medical support throughout the 42-day home isolation phase.
Professor Robin May, chief scientific officer at the UKHSA, said earlier this week that those isolating at Arrowe Park were healthy and showed no symptoms of infection.
Health specialists will continue assessing whether individuals can safely isolate at home or require additional accommodation arrangements.
Officials also stressed that strong public health safeguards remain in place to manage the situation and protect the wider community.
Additional Passengers Brought to UK From South Atlantic Territories
The UK government also confirmed that 10 additional passengers, crew members and close contacts connected to the outbreak are being transferred to Britain from the South Atlantic territories of Saint Helena and Ascension Island.
Authorities said the decision was taken because NHS services in England are better equipped to respond if any of the individuals later develop symptoms.
The transfer operation reflects the growing international coordination involved in managing the outbreak, which has affected passengers from multiple countries.
The UKHSA said all individuals being moved are undergoing precautionary monitoring rather than treatment for confirmed illness.
Three Deaths Linked to Outbreak
The outbreak aboard the MV Hondius has already claimed three lives.
Those who died include a Dutch couple and a German woman. Two of the deaths were laboratory-confirmed hantavirus cases, while an elderly Dutch man died before testing could be completed.
International health authorities continue investigating the exact spread of the virus onboard the vessel.
The Dutch-operated expedition ship had been carrying around 150 passengers and crew from 28 countries during its Antarctic and South Atlantic voyage.
The vessel began its journey on 1 April from Ushuaia before later docking in Spain’s Canary Islands after concerns emerged over illness among passengers.
The ship operator, Oceanwide Expeditions, confirmed that all passengers remaining onboard after the outbreak was identified have now been repatriated to their home countries.
Global Health Authorities Monitoring Situation Closely
The outbreak has prompted concern among international health agencies because hantavirus infections can, in some cases, cause severe respiratory illness or kidney complications.
World Health Organization Director-General Tedros Adhanom Ghebreyesus said there was currently no evidence of a larger international outbreak but warned that additional cases could still emerge.
Health officials have emphasised that containment efforts remain ongoing.
Several countries have implemented quarantine or monitoring measures for returning passengers.
A British man in his 60s is currently isolating at Sacco Hospital after travelling on a flight near a Dutch passenger who later died from the virus.
Although the man has tested negative and remains symptom-free, Italian authorities said he will continue isolating until early June as a precaution.
British Cases Being Monitored Worldwide
The UKHSA confirmed that two British nationals infected with hantavirus are currently receiving treatment in the Netherlands and South Africa.
Another British man with suspected hantavirus remains in stable condition while isolating on the remote South Atlantic island of Tristan da Cunha.
Meanwhile, two additional Britons who left the ship earlier in Saint Helena before the outbreak was formally confirmed continue voluntarily isolating at home in the UK.
The widespread geographic distribution of passengers has required close cooperation between health authorities across Europe, Africa and the South Atlantic.
What Is Hantavirus?
Hantavirus refers to a group of viruses primarily spread through contact with infected rodents, rodent droppings or contaminated environments.
Some strains can cause severe respiratory disease known as hantavirus pulmonary syndrome, while others affect kidney function.
Human-to-human transmission is considered extremely rare, although the Andes strain identified in parts of South America has shown limited transmission between people in certain cases.
Health officials continue to stress that the risk to the general public remains very low.
Experts say the outbreak differs significantly from highly transmissible respiratory viruses such as Covid-19 because close and prolonged exposure is usually required for transmission.
Cruise Industry Faces Renewed Health Scrutiny
The incident has also renewed attention on infectious disease management aboard international cruise vessels.
Cruise ships have previously faced criticism over disease outbreaks because passengers and crew live in close quarters for extended periods.
Following the Covid pandemic, many operators introduced stricter medical screening and sanitation protocols, but health experts say expedition voyages to remote regions can still pose unique challenges.
The MV Hondius is now travelling toward the Netherlands carrying a reduced crew, medical personnel and the body of one deceased passenger.
Authorities said investigations into the outbreak and onboard transmission will continue in the coming weeks.
