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.

To determine the source of contamination, Argentina's health ministry plans to capture rodents for analysis along the route taken by a Dutch couple who first developed symptoms, as they had traveled extensively in Argentina, Chile, and Uruguay before boarding the ship. Since July last year, Argentina has recorded 101 hantavirus cases, with 32 deaths, significantly higher than previous epidemiological seasons. The ministry has reiterated that it is not confirmed

A recent hantavirus outbreak aboard the MV Hondius, an expedition vessel that departed Ushuaia, Argentina, in March 2026, has raised significant concerns. As of current reports, three passengers have died, and one remains in intensive care in Johannesburg, with several additional suspected cases under investigation among passengers and crew. This outbreak is considered unusual due to its occurrence at sea, as hantavirus infections are typically associated with land-based exposure in endemic regions. However, the timing coincides with Argentina's seasonal peak for hantavirus, where recent data

Argentina has seen a significant increase in hantavirus infections, with 101 cases reported since June 2025, double the previous year, and the mortality rate nearly tripling to about one-third of cases. This surge is attributed to warming temperatures and extreme weather patterns, which are expanding the virus's range and allowing infected rodents to move into new regions.
