The first reported death from Hantavirus on the cruise ship MV Hondius involved a Dutch couple, Leo Schilperoord and Mirijam, who boarded in Ushuaia, Argentina. Leo developed symptoms on April 6 and died on April 11, while Mirijam, who was a close contact, died on April 26 after worsening symptoms. The WHO is investigating the outbreak, with hypotheses suggesting the infection may have occurred at a landfill site visited by the couple. Local authorities deny this claim, and the risk to the general population remains low.
