Twelve workers at a Dutch hospital (Radboudumc) were placed in quarantine for six weeks after safety protocols were violated while treating a patient infected with hantavirus from a cruise ship. The breach exposed staff to a virus that can be fatal, and the hospital took precautionary measures to monitor for infection. This is part of a broader hantavirus outbreak linked to the MV Hondius cruise ship that has affected passengers across multiple countries including the Netherlands, Germany, and the United States.
