Jake Rosmarin, who is among the 15 hantavirus-negative passengers quarantining at the University of Nebraska Medical Center after disembarking the MV Hondius cruise ship, shared a video tour of his room on Instagram on Tuesday.

Rosmarin showed off his stationary bike, TV, bed, recliner and desk, saying, “The room is very spacious and comfortable.”

“I’m hoping to give more updates while I’m here. I’m feeling well,” he said.

Rosmarin told ABC News earlier on Tuesday that he is not experiencing any symptoms and plans on remaining in quarantine for the next 42 days.

"I think that is the best decision that's for me and for my family, and I know that here, I'm in the best care possible," Rosmarin said.

Fifteen passengers remain in the quarantine unit and one person remains in the biocontainment unit at Nebraska Medicine, hospital officials said.

The passengers are undergoing in-depth interviews to trace their contacts as well as regular symptom monitoring, officials said.

Two residents of King County, Washington, are being monitored at home after potentially being exposed to hantavirus, the Seattle and King County Public Health Department said.

The two residents sat on a plane near an ill passenger from the cruise ship; that passenger was removed from the plane and later tested positive, officials said.

The two residents don’t have symptoms and are being monitored, officials said.

"Currently, no one in King County has symptoms of hantavirus and there are no cases of the virus in King County," the health department said. "The risk to the public remains low."

A resident of King County is also among the cruise ship passengers now being monitored at the quarantine center in Nebraska, the officials added.

Twenty-five crew members and two medical staffers remain on the MV Hondius cruise ship, which is en route to the Netherlands, Oceanwide Expedition said.

No one on board has hantavirus symptoms but the “medical staff will continue to monitor throughout the remainder of the voyage,” Oceanwide Expedition said.

The ship is expected to arrive on Sunday or Monday. The crew members will follow quarantine procedures when they disembark, Oceanwide Expedition said.

The MV Hondius cruise ship has set sail from Spain after evacuating passengers and crew from 23 countries, Spanish health minister Monica Garcia said.

"Mission accomplished. Thank you to everyone who made this possible. We continue working to protect public health,” Garcia said.

The ship still has "around 30 people, the crew and two health workers, and they will need our support throughout their journey until they reach Rotterdam,” said Dr. Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization. “... We will continue to monitor and support them in any way possible.”
