Active Outbreak — 2026
A cluster of Andes hantavirus cases was detected aboard the Dutch-flagged expedition cruise ship MV Hondius. The first two victims had visited Chile, Argentina, and Uruguay on a birdwatching trip before boarding. Andes virus is the only known hantavirus capable of limited human-to-human transmission. WHO assessed the global public health risk as low.
HPS vs HFRS
Hantavirus causes two distinct syndromes. HPS (Hantavirus Pulmonary Syndrome) dominates in the Americas with ~36% fatality. HFRS (Hemorrhagic Fever with Renal Syndrome) is more prevalent in Europe and Asia with 1–12% fatality depending on strain.
Seasonal patterns
Northern hemisphere HFRS peaks in spring and autumn. HPS in the Americas peaks in spring and summer. Activity correlates with rodent population cycles — particularly bank voles in Europe and deer mice in North America.
