WHO alert: The World Health Organization (WHO) has issued a global alert following a fatal Hantavirus outbreak aboard the cruise vessel MV Hondius. Currently, 11 cases have been identified—nine confirmed and two probable—resulting in three deaths. The fatalities include a Dutch couple and a German national. While the ship was en route from Argentina to Cape Verde, health authorities in France and the United States have confirmed infections among evacuated passengers.
WHO Director-General Tedros Adhanom Ghebreyesus warned that while there is no evidence of a wider community outbreak yet, the virus’s long incubation period means more cases may surface. Experts are particularly concerned as the “Andes” variant involved is one of the few strains capable of rare human-to-human transmission.

The MV Hondius Outbreak
The cruise ship MV Hondius, a vessel known for polar expeditions, became the center of international concern after several passengers exhibited severe respiratory distress. Following the deaths of three passengers, French health authorities reported that one infected woman is currently on a ventilator in Paris, fighting the most severe form of the disease. A U.S. national has also tested positive after being evacuated.
While Hantaviruses are typically localized to specific geographic regions where certain rodent populations thrive, the contained environment of a cruise ship presents unique challenges for containment. The WHO is currently working with maritime authorities to trace all passengers who disembarked during the voyage to prevent further spread.
Understanding the Andes Variant
What sets this situation apart from typical Hantavirus scares is the identification of the Andes variant. Most Hantaviruses are “dead-end” infections, meaning they do not spread between people. However, the Andes strain, native to South America, has a documented history of person-to-person transmission through close contact. This characteristic is why the WHO is urging countries to remain vigilant as passengers return to their home nations.
Recognizing the Symptoms
Hantavirus Pulmonary Syndrome (HPS) can be difficult to diagnose initially because early symptoms often mimic the flu. The incubation period can last anywhere from one to eight weeks after exposure.
-
Early Symptoms: Fever, severe muscle aches (especially in the thighs, hips, and back), fatigue, headaches, and dizziness. Some patients also experience abdominal pain, nausea, and vomiting.
-
Late Symptoms: About four to ten days after the initial phase, the “cardiopulmonary stage” begins. This involves coughing and shortness of breath as the lungs fill with fluid. This stage is life-threatening and requires immediate hospitalization.
Essential Precautions and Safety
Because the virus is primarily shed in the saliva, urine, and feces of infected rodents, hygiene and environmental control are the first lines of defense.
-
Rodent Control: Eliminate nesting sites near living quarters and seal gaps in buildings or vessels where rodents might enter.
-
Safe Cleaning: Do not vacuum or sweep rodent droppings, as this can aerosolize the virus. Instead, spray the area with a disinfectant or bleach solution before wiping it up with paper towels.
-
Personal Hygiene: Frequent handwashing and the use of PPE (masks and gloves) are recommended when cleaning potentially infested areas.
-
Close Contact Monitoring: Given the Andes variant’s nature, individuals who have been in close proximity to confirmed cases should monitor their temperature daily and report any respiratory changes to health professionals immediately.
The WHO continues to monitor the situation, emphasizing that while the risk to the general public remains low, the severity of the disease necessitates a high level of preparedness.
