Frequently Asked Questions

How many hantavirus cases are there in 2026?
As of May 11, 2026, there are 12 cases (7 confirmed, 2 probable) linked to the MV Hondius Andes virus cruise ship outbreak, with 3 deaths (CFR 38%). Globally, 229 cases and 59 deaths were reported in the Americas in 2025.
How many people have died from hantavirus in 2026?
3 people have died in the 2026 MV Hondius outbreak: a Dutch couple and a German national. Globally, 59 hantavirus deaths were recorded in the Americas in 2025 (CFR 25.7%).
Is there a hantavirus case in France?
Yes. As of May 11, 2026, France has 1 confirmed hantavirus case: a French female passenger from the MV Hondius. 5 French nationals are isolated at Hôpital Bichat in Paris, and 22 contacts are being monitored under a government quarantine decree (15–42 days isolation).
Can hantavirus spread from person to person?
The Andes virus (ANDV) is the only known hantavirus capable of limited human-to-human transmission, requiring close and prolonged contact. All other hantavirus strains (Sin Nombre, Puumala, etc.) spread only through contact with infected rodent urine, feces, or saliva — not between people.
What is the hantavirus death rate (CFR)?
Case fatality ratio ranges from <1–5% in Europe (HFRS/Puumala) to 25–50% in the Americas (HPS/Andes). The 2026 MV Hondius cluster has a CFR of 38% per WHO DON600 (8 May 2026). This high rate is partly explained by the passengers' average age of 65.
Where did the 2026 hantavirus outbreak start?
The outbreak was traced to the Dutch cruise ship MV Hondius, which departed Ushuaia, Argentina on April 1, 2026. Patient zero (Case 1, a Dutch male) likely acquired the Andes virus through contact with infected rodents during birdwatching activities in Argentina before boarding.
