Hantavirus Tracker 2026 — Live MV Hondius Case Count | HantaCount

Q: How many hantavirus cases are there in Türkiye?

As of 2026-05-07, Türkiye has reported 1 confirmed or suspected case of Andes hantavirus linked to the 2026 MV Hondius outbreak, with 0 deaths. Counts come from WHO Disease Outbreak News, ECDC threat assessments, and Türkiye's national health authority.

Q: Is hantavirus endemic in Türkiye?

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

Q: What should travellers to or from Türkiye 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 Türkiye, public health is coordinated by Sağlık Bakanlığı Halk Sağlığı Genel Müdürlüğü (HSGM). See https://hantacount.com/en/countries/tr for live counts and the latest official guidance.

Q: How is hantavirus transmitted in Türkiye?

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 Türkiye 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 Türkiye?

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.
