A single Andes virus (ANDV) lineage persisted locally in northern Patagonia from 2018–2025, linked to hantavirus pulmonary syndrome (HPS) cases without evidence of widespread community transmission.
- Why it matters: The outbreak on a cruise ship in 2026 raised questions about how ANDV spread across regions and whether earlier Argentine cases shared a lineage or transmission route.
- What they did: Investigators retrospectively analyzed HPS outbreaks from 2018–2025, reconstructed likely exposure routes for 2026 cruise ship index cases, and compared timing against the expected ANDV incubation period.
- The result: The lineage continuity across 2018–2025 in a defined northern Patagonia area supports a local circulation pattern, but the cruise ship outbreak source remains unresolved, motivating expanded surveillance in endemic regions.
