Tracker Hantavirus 2026 — Compteur en direct des cas du MV Hondius | HantaCount

Q: How many hantavirus cases are there in Pays-Bas?

As of 2026-05-08, Pays-Bas has reported 2 confirmed or suspected cases of Andes hantavirus linked to the 2026 MV Hondius outbreak, with 2 deaths. Counts come from WHO Disease Outbreak News, ECDC threat assessments, and Pays-Bas's national health authority.

Q: Is hantavirus endemic in Pays-Bas?

The 2026 cluster in Pays-Bas is import-related: cases trace back to MV Hondius passengers, crew, or their household contacts. Whether hantavirus circulates endemically in local rodent populations of Pays-Bas is a separate epidemiological question — consult the country's public health authority for endemic surveillance.

Q: What should travellers to or from Pays-Bas do about hantavirus?

Travellers who were on MV Hondius or in close contact with a returning passenger should monitor for fever and respiratory symptoms for 42 days post-exposure. Contact the local health line if symptoms develop. In Pays-Bas, public health is coordinated by Rijksinstituut voor Volksgezondheid en Milieu (RIVM). See https://hantacount.com/fr/countries/nl for live counts and the latest official guidance.

Q: How is hantavirus transmitted in Pays-Bas?

Andes virus (ANDV) is the only hantavirus with documented person-to-person transmission, but it requires close, prolonged contact — typically household members or healthcare workers without PPE. Most Pays-Bas cases are returning MV Hondius travellers or their close contacts. Casual transmission (transit, shops, schools) has not been documented for ANDV.

Q: Is there a hantavirus vaccine available in Pays-Bas?

There is no licensed hantavirus vaccine available in any country as of 2026. Treatment is supportive — early intensive care including extracorporeal membrane oxygenation (ECMO) where available significantly improves outcomes. Prevention focuses on rodent control and avoidance of contaminated environments.
