Deadly Cruise Ship Virus: UK Scrambles to Find Passengers

Health authorities in the UK are engaged in a race against time to trace passengers who left the MV Hondius cruise ship approximately two weeks before a hantavirus outbreak was detected. Seven Britons were among the dozens of passengers who disembarked at St. Helena on April 24, 2026, nearly two weeks after the first reported fatality.

Two of these passengers have since returned to the UK, flying from South Africa. They are currently isolating at home but show no symptoms. UK health officials are actively searching for the remaining five Britons, as well as their family members and close contacts, to mitigate any potential spread of the virus.

The luxury cruise ship, which has recorded three deaths and five confirmed cases of hantavirus, is en route to the Canary Islands. The World Health Organization has warned that more cases could emerge due to the virus's incubation period of up to six weeks. However, the WHO currently assesses the public health risk as low.

Hantavirus is primarily spread through contact with infected rodents, but the Andean strain suspected in this outbreak can rarely transmit between humans. Authorities are focusing on close contacts, such as those sitting next to passengers on long-haul flights, rather than transient encounters. Individuals identified as close contacts may need to isolate for up to six weeks.

Symptoms of hantavirus can initially mimic the flu, including fever and muscle aches, but can progress to severe respiratory issues. The incubation period for symptoms typically ranges from one to eight weeks after exposure. It is possible for individuals to carry the virus asymptomatically, making ongoing monitoring crucial even after negative tests.
