Is Hantavirus a Threat to Europe? Climate Change and Habitat Destruction Increase Risk

An outbreak of Andes-virus on the MV Hondius cruise ship sparked pandemic concerns, with 11 confirmed cases and 3 deaths reported by mid-May 2026. The WHO clarified this is not a COVID-scale threat, as Andes virus rarely transmits human-to-human except via close contact. The article examines how climate change and habitat destruction amplify hantavirus risk globally. Climate affects rodent population dynamics and pathogen distribution; Argentina's 2025 surge (101 cases, 32 deaths) followed drought-rainfall cycles. Europe has endemic Puumala hantavirus, historically transmitted via bank voles with low human-to-human spread and mild-to-moderate disease. Experts warn that warming temperatures may shift rodent distributions across Scandinavia and Central Europe, creating new spillover opportunities. Recommendations include integrating epidemiological, ecological, and climate surveillance systems and investing in climate-resilient public health infrastructure.
