90-Second Read: American Doctor Identified as Hantavirus-Positive Cruise Passenger Explains How He Got His 'Mild Positive' Test Result

Doctor Stephen Kornfield revealed that he is the Hantavirus-positive American passenger from the MV Hondius cruise ship who is currently in isolation. Stephen Kornfeld has revealed that he is the American passenger formerly on board the MV Hondius cruise ship who tested positive for Hantavirus. The doctor was on board the cruise for vacation, but after the ship's doctor got sick, Kornfeld stepped in to assist with passengers who were ill.

The oncologist was vacationing when several of the boat's crew came down with the illness, and stepped in for the boat's doctor once he became too sick. Kornfeld has since been transported to the University of Nebraska's biocontainment unit in Omaha, Neb., where he is quarantining as he awaits more test results. At the time, it felt like this is just some virus and now, in retrospect, there was a question, could it have been Hantavirus?

According to the World Health Organization (WHO), in some cases, symptoms can take up to eight weeks to appear. A French woman who also contracted Hantavirus while onboard the ship is now critically ill, and relying on an artificial lung, a doctor treating her has said. On Tuesday, May 12, Kornfeld appeared on CNN's Erin Burnett OutFront to discuss his condition and the precautions being taken with his quarantine.
