An alert has been sounded to health authorities after the deaths of three passengers on an Atlantic cruise ship following a suspected outbreak of Hantavirus, a rare but dangerous virus.
The case has put the World Health Organization and relevant agencies in South Africa on alert, with authorities trying to map the spread and reduce the risk of new outbreaks.
The journey and the first cases
The incident unfolded on the MV Hondius cruise ship, which had set sail from Argentina about three weeks ago. The itinerary included stops in Antarctica and the Falkland Islands, with a final destination in the Canary Islands.
The first death involves a 70-year-old man who died at sea, with his body being taken to St Helena. Shortly afterwards, his 69-year-old wife collapsed at a South African airport and ended up in a Johannesburg hospital.
A third death was subsequently recorded, with at least three other passengers showing symptoms of the disease.
Critical situation and immediate actions
A 69-year-old British man is fighting for his life in an intensive care unit in Johannesburg. At the same time, an operation is underway to transport two other passengers with symptoms off the ship.
The vessel is anchored in Praia, Cape Verde, with around 150 tourists and dozens of crew members still on board during the crisis.
Features and transmission of the virus
Hantavirus is transmitted mainly through contact with excretions of infected rodents, such as urine or feces of mice and rats, and in rare cases there may be transmission between humans.
The infection can develop into a severe respiratory disease known as Hantavirus Pulmonary Syndrome. Symptoms start with fever and muscle aches and pains and can quickly worsen to shortness of breath and severe coughing.
The virus was again of concern to the international community in 2025, following the death of Betsy Arakawa, wife of Gene Hackman.
International mobilization and investigations
According to the World Health Organization, at least one case has been laboratory confirmed, while epidemiological investigations and genetic analysis of the virus continue.
At the same time, the National Institute of Communicable Diseases is conducting extensive contact tracing, mainly in the Johannesburg area, to identify possible new cases.
The importance of early response
There is currently no specific treatment or vaccine for chantavirus. However, immediate medical intervention is considered crucial for patient survival.
The incident once again highlights the dangers of health crises in confined environments such as cruise ships, particularly during a period of increased global tourist mobility.
