WHO Confirms 7 Hantavirus Cases on Cruise Ship as Death Toll Rises to 3
Reflecto News | Breaking News | Global Health
GENEVA — The World Health Organization announced on Thursday that there are now seven confirmed cases of hantavirus linked to the MV Hondius cruise ship outbreak, as international health authorities race to contain the rare and potentially deadly virus .
Three of the seven confirmed cases have died, and an additional person remains hospitalized in critical condition. Three other individuals with symptoms are being treated aboard the vessel .
“Last Saturday, the United Kingdom notified WHO of a cluster of passengers with severe respiratory illness on a Dutch-flagged cruise ship, the MV Hondius. So far, eight cases have been reported, including three deaths. Five of the eight cases have been confirmed as hantavirus, and the other three are suspected.”
— Dr. Tedros Adhanom Ghebreyesus, WHO Director-General
The WHO had previously reported the outbreak as consisting of a mix of confirmed and suspected cases. The latest update specifies that five of the eight total illnesses are now laboratory-confirmed as hantavirus, while three remain suspected pending test results .
🚢 Global Spread: Cases Reach Switzerland, South Africa, and the U.S.
The outbreak has now spread across multiple continents as passengers disembarked before the ship was quarantined.
- Switzerland: A Swiss citizen who traveled aboard the MV Hondius tested positive after returning home and is receiving hospital care in Zurich
- South Africa: A critically ill patient remains in an intensive care unit in Johannesburg after being medically evacuated from the ship
- United Kingdom: British nationals are among those affected
- United States: Officials from three U.S. states have confirmed that residents who were aboard the vessel are now undergoing health monitoring for potential hantavirus exposure
More than 40 passengers disembarked at the island of St. Helena before the ship reached Cabo Verde, including a Swiss citizen who later developed symptoms and tested positive for hantavirus. The WHO and Public Health England are working to trace the contacts of those who left the ship at that port .
🧬 Virus Type: Andes Strain Capable of Human-to-Human Transmission
Laboratory testing has confirmed that the Andes virus (ANDV) strain of hantavirus is responsible for the outbreak .
This is significant because the Andes strain is one of the few hantaviruses capable of limited human-to-human transmission. Unlike other hantavirus variants — which require exposure to infected rodent droppings or urine — the Andes virus can spread through close, prolonged contact between people, typically within families or between caregivers and patients .
The WHO has confirmed that multiple cases occurred among passengers who shared cabins, consistent with this pattern of transmission . However, the agency emphasized that human-to-human transmission is rare and requires extended close contact, such as sleeping in the same bed or providing direct care without proper protection .
The incubation period for hantavirus ranges from one week to six weeks, with symptoms typically appearing two to four weeks after exposure . Given this timeline, the WHO warned that additional cases may still emerge as passengers and crew complete the incubation window .
🏥 Global Response: Ship Quarantined, Evacuations Underway
The MV Hondius remains anchored off the coast of Cabo Verde with 147 individuals on board — 88 passengers and 59 crew members from 23 nationalities .
Evacuation and treatment efforts:
- Three suspected cases have been evacuated from the ship and are being transported to the Netherlands for medical care
- Two infectious disease specialists are traveling from the Netherlands to board the vessel to provide medical support
- The seriously ill doctor from the ship is being transferred to the Canary Islands by medical aircraft
Spain has formally agreed to receive the vessel in the Canary Islands, following a request from the WHO and the European Union . Cabo Verde lacks the capacity to conduct the necessary medical operations, making the Canary Islands the nearest suitable location .
Upon arrival, passengers and crew will undergo medical examinations and be processed through specially arranged facilities to avoid contact with the local population .
⚠️ What Is Hantavirus? Symptoms, Transmission, and Risk
Key facts about hantavirus pulmonary syndrome (HPS):
| Aspect | Information |
|---|---|
| Incubation period | 1–6 weeks (typically 2–4 weeks) |
| Early symptoms | Fever, muscle aches, fatigue, nausea, vomiting, diarrhea, abdominal pain |
| Late symptoms | Coughing, shortness of breath, rapid progression to respiratory failure |
| Fatality rate | Up to 50% for HPS (Americas) |
| Primary transmission | Inhalation of aerosolized rodent urine, droppings, or saliva |
| Human-to-human transmission | Rare; documented only for Andes virus, requiring close prolonged contact |
The WHO currently assesses the global public health risk from this outbreak as low, as the virus does not spread easily through casual contact and transmission typically requires direct exposure to infected rodents or sustained close contact with an infected person .
