Transcript for US cruise passengers unable to return home
Good evening and it's great to have you with us here on this Wednesday night. And we begin tonight with a very rare look right here in the U.S. Tonight, inside a highly secured bio-containment unit, this one in Nebraska. The first patient to be treated there, an American husband. He and his wife finally allowed off that ship off Japan, but then on the plane home, he came down with a fever. The man's fever spiking during the flight. Whisked off the plane to that special hospital unit, and tonight, he shows us inside the room. The nurse in protective gear, the doors sealed. And tonight, hundreds of others are now being allowed off that ship. Many of them Americans. But could they now face another quarantine before being allowed to go home here in the U.S.? ABC's Clayton Sandell outside that hospital in Nebraska tonight. This is our greeting team. Reporter: When Carl Goldman's evacuation flight from Japan landed in Omaha, he was spiking a fever. My wife touched me and she knew I was burning up. Reporter: Goldman and his wife, Jeri, were fine when they left the diamond princess cruise then Goldman tested positive for coronavirus, becoming the first patient in a bio-containment unit at the university of Nebraska medical center. The doors are specially sealed, so I kind of feel like I'm a fish inside a bowl. Reporter: Tonight, he's giving us the first look inside. I've got Gatorade in every single flavor. Reporter: A pre-existing health issue landed Goldman in the specialized unit, the largest in the country, able to house ten patients. The air circulates 15 times every hour, filtering out hazardous infections. It was last used to treat ebola patients in 2014. There's my nurse in the hazmat outfit. That's the monitor. There's a camera on me. And then double glass everywhere. Reporter: In Japan, Goldman's fellow passengers are finally leaving the diamond princess. Amid new questions about a quarantine that failed to stop the virus from spreading, instead turning the ship into a floating incubator, infecting nearly 700 people. I was so scared of getting covid-19. Reporter: A Japanese doctor, who says he talked his way onboard, says proper procedures and protections were inadequate or ignored. There was no way to tell where the virus is. No green zone, no red zone. Wherever could have virus and everybody was not careful about it. Reporter: A Japanese health official insisting while they didn't have 100% separation, they believe the quarantine functioned effectively. With dozens of Americans still coming off the ship, the CDC is now banning those passengers from entering the U.S., unable to return home until they are symptom-free for another two weeks. All right, let's get back to Clayton Sandell, again with us tonight from Omaha, where that patient is being watched around the clock, and Clayton, do we have any late word on his Reporter: Yeah, David, Goldman tells us he is being checked every three hours. So far, the good news is, he is not showing any signs of a fever, but he and the other 12 patients here are going to have to be totally symptom-free for the next 14 days before they're allowed to leave. Goldman says he is eager to catch another flight, this time home to Los Angeles. David? All right, Clayton Sandell leading us off tonight. Clayton, thank you.
