Norway confirms first European autochthonous Andes virus case

What happened On 06 April 2026, Norwegian health authorities (FHI) confirmed an Andes-virus infection in a 41-year-old researcher hospitalised in Bergen with bilateral pulmonary edema and thrombocytopenia. Both ELISA and RT-PCR were positive for ANDV at the FHI reference laboratory. The patient denies travel to South America in the previous 12 months — the first reported European autochthonous Andes-virus case on record.

What changed since last update The patient remains in critical condition as of WHO DON #600 (08 May 2026). Investigators have narrowed the exposure pathway to imported research-rodent shipments to a Bergen veterinary facility where the patient worked. Whole-genome sequencing of the viral isolate is pending; preliminary phylogenetic placement is consistent with a Patagonian lineage.

Official source summary - Patient: 41-year-old researcher, Bergen, Norway - Exposure: under investigation; suspected imported rodents - Diagnostics: ELISA + RT-PCR positive at FHI reference lab - Status: critical, hospitalised - ECDC posture: Rapid Risk Assessment issued 11 April 2026; risk to general EU/EEA population assessed as VERY LOW

Market impact - Will a second EU country confirm a domestic Andes virus case by June 15, 2026? — directly affected. The Norway case starts the clock; the question is whether a second EU member state confirms a *resident* infection by June 15. - Will WHO declare a PHEIC for hantavirus by Dec 31, 2026? — modestly bullish if research-rodent exposure is confirmed and triggers wider biosecurity reviews; bearish if the case remains a single-source laboratory exposure.

Open questions 1. Is the suspected research-rodent shipment the actual exposure source, or is there an unrecognised European reservoir? 2. Will WGS confirm a Patagonian lineage match? 3. Does ECDC's enhanced-surveillance programme detect a second case before June 15?

Timeline - 06 Apr 2026 — Hospitalisation in Bergen, ANDV-positive on ELISA. - 08 Apr 2026 — RT-PCR confirmation; FHI publishes initial bulletin. - 11 Apr 2026 — ECDC issues RRA 2026-04-RRA-22. - 08 May 2026 — Patient remains critical; case included in WHO DON #600.
