Abstract

As at 18 June 2026, 13 cases (12 confirmed and one probable) of Andes orthohantavirus have been reported (case–fatality: 23%), linked to the Dutch-flagged expedition cruise ship MV Hondius. The event involved individuals from 23 nationalities and required medical evacuation, repatriation, coordinated international contact tracing, isolation, quarantine and clinical and laboratory testing follow-up. To date, all cases have been passengers (10/121; 8%) or crew members (3/61; 5%). Ongoing monitoring and investigations aim to clarify the source of the outbreak, identify risk factors and prevent further spread.
