The World Health Organization (WHO) reported a total of 13 cases, including three deaths, linked to an Andes hantavirus outbreak on the MV Hondius cruise ship as of May 27, 2026. Eleven cases were laboratory-confirmed for Andes virus infection, and two are probable cases. The outbreak was first notified on May 2, 2026, and cases continue to be reported due to the virus's long incubation period of up to six weeks.

Argentina has seen a significant increase in hantavirus cases, with 101 infections and 32 deaths recorded since July 2025, nearly double the previous year's figures. The country is under scrutiny as the MV Hondius cruise ship, linked to a recent hantavirus outbreak, departed from Ushuaia. Argentine health authorities plan to capture rodents for analysis along the travel routes of a Dutch couple who first showed symptoms, who had visited Argentina, Chile, and Uruguay before boarding the ship. The Andes strain, capable of human-to-human transmission, is prevalent in parts of Argentina and Chile.

WHO Report on Hantavirus Cases on a Cruise Ship: Assessment of the Situation for Germany | German Center for Infection Research

The German Center for Infection Research (DZIF) has assessed the implications of the MV Hondius cruise ship hantavirus outbreak for Germany. The cases were caused by the South American Andes virus, known for its rare human-to-human transmission. However, the DZIF states that the risk from indigenous German hantaviruses, such as Puumala, Dobrava-Belgrade, Tula, and Seoul viruses (carried by bank voles and other rodents), remains unchanged, as human-to-human transmission has not been observed for these European strains. The Andes virus does not naturally occur in Europe.
