Summary
- World Health Organization investigating outbreak linked to cruise ship and flight
- Rare hantavirus has killed at least three passengers
- Experts say virus is mainly spread through rodents, not people
NAIROBI, Kenya- A rare but potentially deadly virus is back in the spotlight after a cruise ship outbreak killed three passengers and triggered global health alerts, with the World Health Organization now tracing travellers exposed during a flight to Johannesburg.
The virus, known as hantavirus, has sparked concern due to its severity and the unusual circumstances surrounding the outbreak aboard the MV Hondius.
What is hantavirus and how does it spread?
Hantaviruses are a group of viruses primarily carried by rodents such as rats and mice.
Humans typically get infected through contact with contaminated urine, droppings, or saliva, often by inhaling particles in enclosed spaces.
Experts say transmission between people is extremely rare.
That is why the WHO is closely investigating whether exposure occurred on the cruise ship itself or earlier during travel.
Why the cruise ship outbreak has raised alarm
The outbreak on the MV Hondius has already claimed three lives, including a Dutch couple, with several other cases confirmed or suspected.
One infected passenger died after travelling from Saint Helena to Johannesburg, prompting authorities to trace all passengers on that flight.
The ship remains under scrutiny near Cape Verde as investigations continue.
Experts say three scenarios are possible: rodent contamination onboard, exposure during land excursions, or—least likely—limited human-to-human spread.
Symptoms, risks and why early detection matters
Hantavirus infections can take between one and eight weeks to show symptoms.
Early signs often resemble flu, including fever, fatigue, and muscle aches, making diagnosis difficult.
In severe cases, the virus can lead to lung failure or kidney complications.
Fatality rates vary widely—ranging from about 1 pc to 15 pc for some strains, and up to 40 pc for more severe forms found in the Americas.
There is currently no specific cure.
Treatment focuses on supportive care such as oxygen therapy and intensive monitoring, making early medical attention critical.
What happens next as WHO tracks global exposure
The WHO has launched contact tracing for passengers who may have been exposed during travel, particularly on the Saint Helena–Johannesburg flight.
Health authorities are urging anyone affected to report symptoms immediately.
The incident highlights how quickly rare diseases can trigger international concern—especially when travel is involved.
Investigations are ongoing to determine the exact source of the outbreak and prevent further spread.
