Patient zero of the hantavirus epidemic on a cruise ship has been identified as ornithologist (researcher who studies birds) Leo Schilperoord, whose passion cost him his life.

The 70-year-old man and his wife, Mirjam Schilperoord, 69, had been traveling in South America for five months.

Il Messaggero writes that they arrived in Argentina on November 27 and continued their journey to Chile and Uruguay, then returned to Argentina at the end of March, where they undertook a fateful birdwatching excursion.

The couple, originally from Haulerwijk, a small village of 3,000 inhabitants in the Netherlands, were identified in obituaries published in the town's monthly newsletter.

The Ushuaia landfill is where Argentine authorities suspect the Dutch couple inhaled particles from the feces of long-tailed rice rats, carriers of the dangerous "Andean" variant of hantavirus, the only known form that can be transmitted from human to human.

On April 1, the couple boarded the MV Hondius from Ushuaia, along with 112 other people, many of whom were also birdwatchers or scientists.

On April 6, Leo developed a fever, headache, stomach ache and diarrhea. He died on board the ship five days later.

Mirjam disembarked from the ship, along with Leo's body, on April 24, during a planned stopover on the Atlantic island of Saint Helena. She took a plane to Johannesburg, South Africa, and then another KLM plane to the Netherlands, but never arrived at her destination.

The crew found her too ill to fly and were forced to remove her from the plane at that point. Mirjam collapsed at the airport and died the next day.
