Hospital on alert after hantavirus blood mishandling forces 12 staffers into quarantine | 13 May 2026 | A Dutch hospital has quarantined a dozen staff members after reports of a protocol breach involving a patient infected with hantavirus, hospital officials said Monday. The breach occurred last week at Radboud University Medical Center in Nijmegen, Netherlands, after the facility admitted a patient tied to a rare and deadly hantavirus outbreak aboard the MV Hondius luxury cruise ship. The hospital said the patient’s blood and urine were not processed and were not disposed of using the strictest international protocols required for handling the specific hantavirus strain. “Because of these circumstances, 12 employees will go in preventive quarantine for six weeks as a precaution despite the fact that the chance of infection is small,” the hospital said.
