The hantavirus outbreak linked to the cruise ship MV Hondius has grown again.As of May 12, the World Health Organization has confirmed a total of 11 cases connected to the vessel — nine confirmed and two probable — with three deaths. Two new cases were reported in the latest update, continuing a pattern of steady growth since the outbreak was first identified last month.The WHO is not sugarcoating what comes next.“We expect more cases given the dynamics of spread on a ship and the virus’ incubation period,” officials stated — a direct acknowledgment that the numbers are not done climbing. The Andes strain responsible for this outbreak has an incubation period of up to six to eight weeks, meaning passengers who left the ship weeks ago may still be in the window where symptoms could develop.The critical line from the WHO update: “At the moment, there is no sign that we are seeing the start of a larger outbreak.”That distinction matters. All 11 cases remain linked to the ship — passengers or crew. There is currently no confirmed evidence of sustained community spread beyond those direct connections, despite the suspected third-generation case in Italy that authorities are still investigating.Eighteen American passengers are being monitored at medical facilities in Nebraska. Cases have been identified across the Netherlands, France, Spain, Germany, Switzerland, and the United Kingdom. The ship itself is now sailing to Rotterdam, where it will be disinfected after the crew disembarks.The outbreak is not over. The WHO is watching every new case closely.So should the rest of us.
