The grim-faced captain had bad news for the people gathered in the lounge of the MV Hondius. One of their fellow passengers had died.<\/p>\n
\u201cTragic as it is, it was due to natural causes, we believe,\u201d the captain, Jan Dobrogowski, told them on April 12. He added that the ship\u2019s doctor had said the man was \u201cnot infectious, so the ship is safe.\u201d<\/p>\n
Less than two weeks earlier, the captain had convened the same group for a celebratory toast, as the Hondius left Argentina to sail the south Atlantic for bird watching and wildlife spotting on some of the world\u2019s most remote islands.<\/p>\n
Now, passengers consoled the dead man\u2019s widow, Mirjam Schilperoord\u2011Huisman, 69, of the Netherlands. She and her husband, Leo Schilperoord, also 69, had crossed South America in pursuit of rare birds. Some asked if she would prefer that the trip be cut short.<\/p>\n
\u201cEveryone is here for a purpose,\u201d she responded, according to \u200b\u200bRuhi Cenet, a Turkish documentary filmmaker who was on the ship. She urged her fellow bird watchers to push on because her husband \u201cwould have wanted me to do the same.\u201d<\/p>\n
Within weeks, two more passengers, including Ms. Schilperoord\u2011Huisman, would be dead. The cause, health officials say, was almost certainly the Andes<\/a> species of the hantavirus, a family of viruses carried by rodents that can spread between humans.<\/p>\n
