WHO says human hantavirus spread 'possible' after cruise ship cases

scienceMay 13, 202625548

WHO's Disease Outbreak News on May 13, 2026 linked a multi-country hantavirus cluster to cruise-ship travel after infections were detected among passengers, and at least three people have died. Several passengers developed Hantavirus Pulmonary Syndrome requiring isolation and critical care as cases surfaced across Europe and North America when travelers disembarked. The Illinois Department of Public Health is separately investigating a hantavirus case tied to cleaning a home with rodent droppings, indicating at least one infection unrelated to the cruise. This matters because hantavirus can cause rapid respiratory failure and cruise travel can move infections across borders, so public health teams are tracing contacts and emphasizing rodent control and early medical evaluation for exposed people.
