The World Health Organization (WHO) has confirmed six laboratory-verified cases of hantavirus, specifically the Andes virus strain, associated with the MV Hondius cruise ship, which docked in Tenerife, Spain on May 10, 2026. The outbreak has resulted in three deaths, with four individuals currently hospitalized in South Africa, the Netherlands, and Switzerland. Health authorities are closely monitoring the situation, and additional suspected cases have emerged in Spain and on Tristan da Cunha, linked to passengers who disembarked earlier. The WHO has assessed the risk to the general public as low, but noted a moderate risk among close contacts aboard the ship due to the confined environment. Passengers are being evacuated and screened to minimize contact with the local population. The Andes strain is notable for its potential to spread from person to person, albeit rarely. Symptoms of hantavirus infection can resemble severe flu and may progress to serious respiratory issues, with a fatality rate of up to 50% in severe cases. Medical experts advise anyone experiencing flu-like symptoms after potential exposure to seek immediate medical attention.
