Hantavirus Cruise Ship Outbreak Triggers Global Health Alert

Health authorities around the world are racing to trace passengers who left the cruise ship MV Hondius after a deadly hantavirus outbreak claimed three lives and infected several others. The ship, which became stranded near Cape Verde, has sparked international concern as officials work to contain the rare but dangerous Andean strain of the virus.

According to the World Health Organization (WHO), the outbreak resulted in the deaths of a Dutch couple and a German passenger. Eight additional cases are currently under investigation, including one involving a Swiss citizen. The Andean strain of hantavirus is particularly alarming because, unlike most hantavirus variants, it can spread between humans through close personal contact.

Dutch authorities revealed that approximately 40 passengers disembarked in Saint Helena before the outbreak was officially detected. Officials are now attempting to locate those travelers, whose movements remain largely unknown. One notable case involved the wife of a Dutch victim, who became ill during her journey home and later died before reaching the Netherlands.

Dutch airline KLM confirmed that the woman was removed from a flight in Johannesburg on April 25 after her condition worsened. Meanwhile, global health agencies, including the U.S. Centers for Disease Control and Prevention (CDC), are closely monitoring the situation. The CDC stated that the risk to the American public remains very low.

France confirmed that one French national had contact with an infected individual but currently shows no symptoms. Argentina has also launched rodent testing operations in Ushuaia, the departure point of the expedition cruise.

The MV Hondius, carrying nearly 150 passengers and crew, is expected to arrive in Tenerife, Spain, by Saturday. Spanish authorities plan to quarantine 14 Spanish passengers in a military hospital near Madrid, while foreign nationals will be repatriated if they remain symptom-free.

Three infected passengers were evacuated for medical treatment in Europe, highlighting growing international efforts to prevent further spread of the hantavirus outbreak in 2026.
