Argentina is the historical heartland of Andes virus, the only hantavirus species with documented person-to-person transmission. Cases concentrate along the Andean spine and Patagonian forest belt, with three endemic clusters and a marked uptick through 2025–2026.

Three endemic clusters

Andean Patagonia (Río Negro, Chubut, Neuquén) — forest-edge exposure, highest CFR. Northwest (Salta, Jujuy) — agricultural exposure during sugarcane harvest. Central / Pampean (Buenos Aires, Santa Fe, Entre Ríos) — mixed rural and peri-urban exposure.

The 2026 cruise outbreak

On 8 May 2026 the WHO confirmed six suspected Andes-virus cases on a transatlantic cruise that had departed Buenos Aires three weeks earlier. Three passengers died. Genomic sequencing tied the cluster to a clade circulating in Río Negro — the largest documented Andes-virus person-to-person event in twenty years.

Risk for travellers

Most travellers face negligible hantavirus risk. The handful of historical traveller-acquired cases involved overnight stays in rustic cabins or refugios in Andean Patagonia between October and April, where rodent waste in poorly ventilated buildings creates aerosolisable exposure.
