Newly released footage shows the captain on board m/v Hondius announce the death "by natural causes" of a Dutch national passenger, 25 days before the first known case. The announcement was made on 12 April 2026, and no evidence of a virus or contagion was present on the vessel. It was not until 6 May that FOPH confirmed that a passenger who travelled on the first leg of the voyage had tested positive for hantavirus and is currently being treated at the University Hospital Zurich. #hantavirus #cruise #outbreak #atlantic #news
