Three people from a cruise ship at the center of a deadly hantavirus outbreak, including the ship’s doctor, are being flown to the Netherlands for medical care. Three people have died, and the World Health Organization says eight cases have been recorded in all. Some 150 passengers on the Dutch ship, the MV Hondius, are isolating in their cabins. The rare virus usually spreads when people inhale contaminated residue of rodent droppings. It can spread person-to-person, although the World Health Organization says that is rare. The ship remained near the Cape Verde islands off West Africa on Wednesday, and is preparing to head to Spain’s Canary Islands.
