Virus from Argentina Spreads Globally: Cruise Victims Recorded Across Three Continents
World
Argentine authorities and the World Health Organization (WHO) are conducting an emergency investigation into the causes of a hantavirus outbreak (Andes virus strain) aboard the cruise ship MV Hondius. The vessel, which departed from the port of Ushuaia on April 1, became the epicenter of an infection that has already claimed victims among Dutch and German citizens.
Chronicle of Tragedy and Virus Geography
The first victim was a 70-year-old Dutchman who died on board on April 11. Later, the disease took the life of his wife in Johannesburg and another passenger from Germany. It is currently confirmed that the virus has crossed oceans: infected individuals have been identified in Switzerland, while dozens of passengers under observation have returned to the US (Georgia, California, Arizona) and European countries. Argentina has already begun sending genetic material of the virus to laboratories in the UK, the Netherlands, and Spain for rapid diagnosis.
The Argentine Connection
Argentina is officially recognized by the WHO as the country with the highest incidence of hantavirus in the region. Since June 2025, the number of infections in the country has doubled, reaching 101 cases. Investigators are trying to determine whether the infection occurred in Ushuaia before boarding or on the ship itself. The Andes virus is particularly dangerous because, unlike other hantaviruses, it can be transmitted from person to person through close contact. The mortality rate of the disease is nearly 30%, causing severe pulmonary syndrome.
The Climate Factor
Infectious disease experts, such as Hugo Pizzi, are sounding the alarm: climate change is turning Argentina into a tropical zone, facilitating the uncontrolled breeding of rodents—the virus carriers. Warming temperatures are expanding the rodents' habitat, making human encounters with the infection in the wild and in ports increasingly common.
Currently, the MV Hondius is heading toward the Canary Islands. Although the WHO assesses the overall public health risk as low, a scandal is growing over the liner's docking in Tenerife: local authorities fear the introduction of "Argentine fever." This situation has become a stark reminder of how ecological shifts can turn a tourist route into a biological hazard zone.
