An oncologist traveling on the cruise ship at the center of a hantavirus outbreak says he's the lone American isolated at a special biocontainment unit in Nebraska.
Dr. Stephen Kornfeld of Bend, Oregon, says he volunteered to help care for fellow passengers who began getting sick aboard the MV Hondius in April. He was among more than 120 passengers and crew evacuated from the ship, and flown to different countries to enter quarantine.
