UK and US Monitor Hantavirus Cases Linked to Cruise Ship Outbreak
The BBC reported Wednesday that health authorities in the United Kingdom and the United States have launched disease monitoring measures following a hantavirus outbreak aboard the cruise ship MV Hondius. Passengers had already disembarked before officials raised the alarm.
Confirmed Cases and Where Patients Stand Now
Three people have tested positive for hantavirus linked to the vessel. A Dutch woman has died. A British passenger remains in intensive care in South Africa. A Swiss national is receiving treatment in Zurich. Five additional suspected cases have been identified, including a British man, a Dutch crew member, and a German national. Two of those suspects arrived in the Netherlands for treatment. A third remains on a delayed evacuation flight in a stable condition. Two British passengers who left the ship earlier are isolating at home after potential exposure, though neither has shown symptoms.
US States Step In as Disembarked Passengers Return Home
Authorities in Arizona and Georgia confirmed to the BBC they are tracking three American passengers who left the MV Hondius before it reached Cape Verde. None of those individuals is currently displaying symptoms. The UK’s Health Security Agency separately confirmed the two British passengers isolating at home departed the ship earlier in its voyage from Argentina across the Atlantic.
Background: What Makes the Andes Strain Unusual
Hantaviruses take their name from a river in South Korea and describe a broad family of pathogens, not a single disease. The World Health Organisation lists more than 20 viral species in the family. Nearly all are linked to exposure to rodent droppings, urine, or saliva, usually through inhalation. One strain stands apart. The Andes virus, dominant in Argentina and Chile, is the only known hantavirus variant capable of spreading between humans, though transmission remains rare and requires prolonged, close contact. It is not transmitted like influenza through casual airborne droplets. South Africa’s health minister confirmed the Andes strain in the British patient in Johannesburg and the Dutch woman who died.
What Happens as the Ship Heads to the Canary Islands
The MV Hondius is carrying 146 passengers from 23 countries and is expected to reach the Canary Islands by the weekend. Passengers are confined to their cabins to limit exposure. Authorities plan full medical assessments on arrival before anyone travels home. The WHO has been operating on the assumption of both rodent contact and human-to-human spread aboard the vessel. Genetic analysis of the virus may eventually clarify how the outbreak began. A Dutch couple, since deceased, had traveled through South America before boarding in early April. The ship also visited remote wildlife areas during its voyage, leaving open the question of exactly where and how the first infection occurred. Experts say the broader global risk remains very low, with no evidence the outbreak has moved beyond the ship.
