MADRID—Health authorities across four continents Thursday were tracking down and monitoring passengers who disembarked a hantavirus-stricken cruise ship before its deadly outbreak was detected, and trying to trace others who may have come into contact with them since then.
In Argentina, a team of investigators has yet to leave for the southern town where they suspect the outbreak originated, officials from the country’s Health Ministry told The Associated Press on Thursday. The Argentine investigators suspect a Dutch couple may have contracted the virus while on a bird-watching trip before they boarded the cruise ship.
