Hantavirus cases in Royaume-Uni
Royaume-Uni 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
Three Hondius passengers confirmed PCR-positive by UK Health Security Agency; all under hospital monitoring. Third case announced 11 May after repatriation flight from Tenerife.
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. Royaume-Uni 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.
The 42-day window, ring tiers, and what investigators actually do.
