International Coordination Underway to Contain Andes Hantavirus Outbreak on Atlantic Cruise Ship

A deadly Andes hantavirus outbreak was detected aboard the luxury cruise ship MV Hondius in early May 2026, with nine probable cases and three confirmed deaths. The vessel departed Argentina on 1 April, visiting remote Atlantic locations before reaching the Canary Islands. Initial cases included a 70-year-old Dutch passenger who died onboard, his 69-year-old wife (deceased in South Africa), and a German woman. Additional cases emerged among crew and passengers, with three British nationals confirmed infected. By 6 May, the ship anchored off Tenerife; remaining 149 passengers underwent controlled evacuation. The outbreak's likely origin traces to one or two individuals infected in South America pre-embarkation with limited onboard transmission. WHO-coordinated international response involves Dutch, Spanish, and other affected nations. Expert assessment indicates manageable containment risk given the virus requires sustained close contact for human-to-human transmission, contrasting favorably with pathogens like COVID-19.
