Hantavirus Tracker: MV Hondius Current Status
Hantavirus Tracker is an independent tracker for the multi-country Andes hantavirus cluster linked to the MV Hondius cruise ship. Verified case counts, route map, passenger status and timeline, updated manually from WHO, ECDC and CDC briefings.
Latest official update
2026-05-28: WHO's fourth Disease Outbreak News reports 13 total cases as of 27 May (11 confirmed Andes virus, 2 probable) and 3 deaths (case fatality ratio 23%). Three new confirmed cases since 13 May — one each from Canada, the Netherlands, and Spain — were found through contact follow-up and routine testing; a previously inconclusive U.S. case tested negative and was removed. Over 600 contacts are monitored across 32 countries, and the effective reproduction number was 0.7 as of 22 May, indicating declining transmission.

What We Know So Far
Current count. The latest official update (WHO Disease Outbreak News (DON604), 28 May 2026) reports 13 total cases: 11 confirmed Andes virus infections, 2 probable, 0 inconclusive, 0 suspected, and 3 deaths.
Why Andes virus matters. Andes virus is the only hantavirus with documented limited person-to-person transmission, typically in cases of close and prolonged contact.
Why monitoring lasts 42 days. CDC lists the Andes virus incubation period as 4 to 42 days after exposure. WHO recommends a 42-day monitoring window from last possible exposure. The window for this cluster ends on 2026-06-21.
Risk to the general public. WHO, ECDC and CDC say the public-health risk to the general population remains low. Identified contacts are being monitored and isolated where appropriate.
