An American oncologist who traveled on a cruise ship at the center of a hantavirus outbreak has been cleared to leave a special biocontainment isolation unit in Nebraska. Multiple outlets report that Dr. Stephen Kornfeld, from Bend, Oregon, was among more than 120 passengers and crew evacuated from the ship and taken for quarantine-related monitoring in different countries. Kornfeld was brought to the University of Nebraska Medical Center in Omaha with 15 other Americans. Because a nasal swab Kornfeld took on the ship produced inconclusive results for hantavirus, hospital officials moved him to an isolated biocontainment unit while he was the only American in that higher-containment setting. The University of Nebraska Medical Center later announced that Kornfeld will leave the biocontainment unit and instead join the other 15 Americans who are monitored through the National Quarantine Unit. Sources also describe Kornfeld’s role in caring for fellow passengers who became sick aboard the ship and note that the hospital spokesperson Kayla Thomas said the change reflects updated clearance.
