Hantavirus cases in アメリカ合衆国
アメリカ合衆国 is one of 14 countries with confirmed cases linked to the 2026 MV Hondius hantavirus outbreak. This page tracks the local count, lists the attributable events, and updates every time the underlying dataset is revised.
Country note
One of 18 repatriated American passengers confirmed PCR-positive for Andes hantavirus (asymptomatic at testing); transported in a biocontainment unit to the Nebraska Biocontainment Unit at UNMC. As of 12 May: 16 Americans at Nebraska facility (1 in biocontainment/confirmed, 15 under 42-day monitoring); 2 at Emory University Hospital Atlanta ASPR RESPTC (1 symptomatic, PCR pending; 1 monitoring).

Context
The 2026 outbreak is caused by Andes virus (ANDV), the only hantavirus with documented person-to-person transmission. The index event is a cluster aboard the Dutch-flagged cruise ship MV Hondius. アメリカ合衆国 cases are either:
- Returning passengers or crew of the MV Hondius
- Household or close-contact cases of returning travellers
- Suspected pre-cruise exposures (rare, currently under investigation)
The country's national focal point reports cases up to WHO and ECDC; we update from those publications.
What to watch for if you were on the Hondius or in close contact with a returning traveller.
