I saw another article - can't find it now - with statements to the effect that transmission of Andes strain hantavirus is typically only between very close contacts, like amongst partners. But already the original couple who traveled in the endemic area of the Andes virus prior to boarding the ship have apparently spread it to another couple on the ship, the ship's doctor, 2 crew members and additionally the person who has tested as positive in Switzerland.
