An oncologist traveling on the cruise ship at the center of a hantavirus outbreak has been cleared to leave a special biocontainment unit in Nebraska. Dr. Stephen Kornfeld of Bend, Oregon, was among more than 120 passengers and crew evacuated from the ship and flown to various countries for quarantine.
Kornfeld helped care for fellow passengers who became sick on board and was brought to the University of Nebraska Medical Center in Omaha with 15 other Americans, but he was the only one taken to an isolated biocontainment unit after a nasal swab he took on the ship produced inconclusive results on whether he had the virus.
